Kistler's Lorch Production Site
Commissions New Calibration Unit for Torque Sensors and Torque Systems |
| |
 Kistler
has commissioned an additional calibration unit for torque sensors on
its Lorch production site. Acceptance and accreditation by the DAkkS
(formerly DKD) in December 2009 means Kistler's Center of Excellence for
Torque Sensors now has two high-precision calibration units approved by
this German accreditation body. The new system for sensors with a torque
rating of up to 5 000 N•m is a machine with a sliding weight, automated
calibration sequence and automatic disturbance variable compensation.
New software now allows automated adjustment and calibration of torque
sensors. The very low best measurement capability of 100 ppm is a sound
basis for extremely accurate development and calibration of torque
sensors. Outside the "Physikalisch-Technische Bundesanstalt" in
Brunswick there are only two other calibration units in Germany with
similar characteristics and best measurement capabilities for this type
of measurement. As the new unit likewise determines the best measurement
capability of the calibrated sensors, in future Kistler can also issue
its customers calibration certificates that are more detailed in this
respect. These best measurement capabilities ... |

Sensor Technology provides the key to
learning |
| |
|
Sensor Technology Ltd: The electrical machines laboratory at the
Dublin Institute of Technology (DIT) has greatly increased in its
effectiveness as a teaching resource since TorqSense non-contact torque
sensors from Sensor Technology have been fitted to five machine sets.
The new sensors replace an existing system of machine monitoring that
had proved inaccurate. To provide maximum flexibility, the demonstration
equipment in the DIT machines laboratory employs modular construction.
This means, for example, that experiments with both AC and DC machines
can be carried out on the same test bed, as whichever machine is needed
is simply clamped into place. Whatever the configuration of the
equipment, however, the experiments and demonstrations performed in the
laboratory require the monitoring and collection of a number of key
operating parameters, including torque, speed and ... |

Manner's torque measuring flange now with
Ethernet connection |
| |
 Manner
Sensortelemetrie has now widened its range of torque measuring
flanges, developed specifically for test bench technology. The focus is
now on expanding network connectivity. Ethernet connection (TCP/IP) is
now available alongside existing USB and CAN network links. This means
that the torque sensor can be smoothly integrated into existing TCP/IP
networks. Ethernet technology offers huge advantages, particularly with
larger test benches. The fibre optic cables generally available for
Ethernet use permit transmission paths up to several kilometres long, as
well as transmission of measurements that is completely free of
interference. The rotary speed data collected using the integrated speed
measurement system is also transmitted. The classic data recording
interface is no longer needed, which cuts costs greatly. The measuring
flange, together with a PC, represents a practically "Plug and Play"
data acquisition system. ... |

Talking Sense about Technology Transfer |

 Sensor
Technology Ltd: Technology transfer may prove one of the cornerstone
engines for growth as the UK emerges from recession over the coming
months. Sensor Technology in Oxon are virtually addicted to the habit,
so we asked their Tony Ingham how it has shaped the company’s
development and what the future holds. Wireless became one of the
buzzwords of the late Noughties, and ‘wireless’ got our grandparents’
generation excited too in the 1940s. But between those periods the word
was not much used – except at Sensor Technology around the turn of the
Millennium. “We’d identified a way to measure the torque in a rotating
shaft without maintaining physical contact – well, the theory of how to
do it!” says Tony Ingham. “Doing away with the traditional slip rings
would be a big advantage in many potential applications, and we kept
thinking of more and more reasons to develop the concept.” Sensor

systems. The ultimate fields of precision manufacture, such as
electronics, biophysics and thin film deposition where tolerances are
measured in atoms, are often conducted in hard vacuum to remove airborne
contaminants and avoid the performance reducing effects of tiny air
movements. However the vast majority of vacuum chamber designs require
seals for rotary drive shafts (called rotary feedthroughs) and
‘feedthroughs’ for the passage of materials, components, tools and

Sensor hones in on sharp operators |

Sensor
Technology Ltd: Risk is being driven out of the use of heavy duty
diamond cutting tools thanks to a Euro 800,000 EU-backed research
programme at Greenwich University in London, to determine the true
operating characteristics of such equipment. At the heart of this vital
work is a high tech torque sensor from Sensor Technology in Banbury,
which proved to be the only effective way of measuring the true toque in
the rotating saw blades and drill bits. Previous research has simply
estimated the torque by calculation from the drive motors’ current
requirements and consumption. This was known to be highly inaccurate,
because every motor has its own unique signature of characteristics,
which can have a significant effect on actual performance in highly
demanding applications, such as drilling 1000mm bore holes through
reinforced concrete, or sawing through the barnacle encrusted steel of
sub-sea structures. In order to accurately profile the performance of
each tool, it is necessary to measure the torque of the blade or cutting
tip as it rotates; and for this a non-contact sensor is required. The
Greenwich team considered several options around which to build their
test rig, and the clear winner was the TorqSense unit from Sensor
Technology. This is a transducer that requires no physical contact
between the sensor mounted on the high speed tool and its adjacent
static pick-up, instead using Rayleigh Waves or surface acoustic waves

The all-rounder for measuring torque at
an optimal price – the T40 torque flange with increased measurement
ranges |
| |
|
The
all-rounder for measuring torque – at an optimal price – the T40 torque
flange from HBM is now available with two new nominal (rated)
torques of 5 kN•m and 10 kN•m. The T40 measurement flange series
therefore now covers the nominal torque ranges from 500 N•m to 10 kN•m
and can be used for practically all test bench applications. The compact
design of the T40 simplifies integration in a test bench. The torque
flange is extremely robust and copes with very large impact and
vibration loads. As per EN 60068-2-6, the vibrational stress was tested
in all three spatial directions. The T40 had to withstand accelerations
of up to 20 g for two and a half hours in the frequency range 10 Hz to 2
kHz. Data transmission between rotor and stator is digital in the T40,
so that secure, error-free measured value acquisition and transmission
is possible even under difficult ambient conditions, for example
electromagnetic interference or fluctuating temperatures. In addition,
the measurement flange does not use slip rings or bearings and is
therefore totally maintenance and wear-free. This results overall in
very high reliability that leads to significantly reduced test bench
down times. The measured torque can be output either via a voltage
output or a frequency output. The interface module TIM 40 can be used to
supplement the torque flange with even more interfaces. This provides

Non-contact torque sensor now mounts in
moments |
| |
|
Sensor
Technology Ltd: The latest model of TorqSense, the non-contact
digital torque measuring system, incorporates an integral sprocket or
pulley, allowing easy fit-and-forget mounting in a vast range of plant
and machinery such as drum mixers, generators, pump, dynamometers and
conveyor drives. Earlier models of TorqSense provided an in-line shaft
for connection to the equipment under test. While these are suitable for
many situations, sometimes mean a degree of engineering was necessary to
mount the unit. This prompted torque system manufacturers Sensor
Technology, of Banbury, to develop this new user-friendly series of
models. The new RWT 350/360 TorqSense is suitable for virtually any
plant driven by a belt or chain drive, particularly those where space is
limited or access restricted. The ease of fitting is also likely to be
of interest for jobs where it is essential to minimise downtime, such as
in continuous process plant. “Belt and chain drives naturally have a
high radial load, which has to be accounted for when mounting a standard
TorqSense,” explains Tony Ingham of Sensor Technology. ... |

New torque sensor will revolutionise
machine control |
| |
|
Machine
designers have been presented with a significant new technology for
measuring power in drive shafts and other rotating machine elements,
following the launch of the RWT310/320 series of TorqSense Rotary Torque
Sensors by developers Sensor Technology Ltd. Unlike traditional
slip ring transducers, the RWT units make use of a simple non-contact
measurement technique of a radio frequency (RF) couple for power and
signal communication. This means that the units are mechanically
straightforward and as such they stand to completely redefine the
expectations of machine builders and control engineers, who to date have
had to put considerable time and expense into obtaining the accurate
torque readings essential for accurate machine control and production
monitoring. They feature integral electronics with outputs for torque,
speed, power and angle. The RWT310 provides analog outputs and the
RWT320 both analog and digital outputs, which are directly compatible
with PC Interfaces such as serial and USB, being user programmable for
signal levels. Other innovative features include built-in peak torque
sampling, storage and torque averaging, and a self-diagnostics test
package. Both the RWT310 and RWT320 can operate from a wide range of ... |

Reducing Engine Friction |
| |
|
Sensor
Technology Ltd: An innovative torque sensor is helping to reduce
engine emissions and improve economy as part of a project to develop an
intelligent lubrication system. With engine efficiency under the
spotlight like never before, automotive companies are exploring all
avenues for improving performance. And because engines have a rotating
power output, torque is the key measurement. Car engines are the bett
noir of the environmental lobby. There is no doubt that they are major
contributors to carbon build up. But equally they are fundamental to
modern life. A true replacement is decades away, so we have to make them
as efficient as possible. Engine lubrication systems are essentially
dumb. They have a simple mechanical pump which has been sized to ensure
an adequate supply of oil in the worst operating condition. This is
typically a hot engine at idle. The pump is thus hugely oversized for
most of the rest of the speed range and, as a consequence, nearly 60% of
its output is dumped straight back into the sump via the relief valve.
It will also deliver the same amount of oil to every part of the engine
regardless of what that system might actually need. The pump is also
insensitive to engine load and thus the bearings will receive the same
oil supply at a given speed regardless of the load. ... |

Torque about Improving Handling Accuracy |
| |
|
Sensor
Technology Ltd: Dry bulk handling is following many other industrial
processes that have been redeveloped from a ‘black art’ to a highly
accurate and controlled procedure. A generation ago much of industry was
in the hands of time-served artisans who relied on their many years
experience to tweak and tease operations to ensure a good result.
Usually they were unable to explain why they made the decisions they
did, but the results generally turned out OK! While the idea of horny
handed sons of toil is all very romantic, it is hardly the stuff of
modern industry where precision has to be the watchword – where margins
and timetables are so tight that every thing must be controlled to
within very demanding tolerances. Computers have of course been crucial
to this advancement, and it is developing the ability for them to ‘see’
what is actually going on and constantly retune the process that is the
heart of the matter. “Technically we call this real time data
collection,” says Tony Ingham of Sensor Technology Ltd, one of the ... |

PCB Piezotronics In-Line Rotary Torque Sensor System Series |
| |
|
PCB Automotive Sensors Division introduces Series 5300D TORKDISC®
In-line Rotary Torque Sensor Systems designed for test applications
requiring a robust rotary torque transducer where axial space is at a
premium. Onboard, the transducer is a field proven electronic module
that converts the torque signals into a high-speed digital
representation. Once in digital form, this data is transmitted to a
non-contacting pick-up loop, with no risk of noise or data corruption. A
remote receiver unit converts the digital data to a high-level analog
output voltage, and a serial digital output. Series 5300D incorporates
dual high level analog outputs, AC and DC coupled, providing both static
and dynamic torque measurement capability that can be recorded
separately and independently scaled; which is particularly beneficial
when high DC levels are present or when low levels of AC content is of
particular interest. Series 5300D also features industry leading DC
bandwidth to 8500 Hz, resulting in increased dynamic response
characteristics. The DC coupled output features an 8-pole low pass
elliptical filter with user selectable frequencies for minimal roll off
at each filter selection. A 2-pole Butterworth high pass filter with a
wide range of user selectable cut off frequencies is included with the
AC coupled output. Series 5300D TORKDISC® units are ideal for
applications such as automotive engine, powertrain & chassis dynamometer

Sensor
Technology Ltd: A company that designs and build custom test
equipment for the manufacturing and research industries has developed a
cost saving sub-system that allows eight dynamometer test rigs to share
a single calibration unit based on a Digital TorqSense transducer from
Sensor Technology Ltd. The company, 1st Pass of Westbury in Wiltshire,
started out as a regional systems integrator for National Instruments’
LabView software packages. However, it quickly realised that there was a
considerable need for a wider service encompassing all aspects of test
rig design and build. Founder and Managing Director, Chris Turner,
explains: “Engineers involved in either research or quality control need
test rigs, but designing them is not their forte. They tend to focus
only on the immediate requirements so tend towards inflexible,
mono-functional designs. Six months later when new requirements emerge,
they have to build another rig”. ... |

Servo research points the way to improved
dynamics |
| |
|
Sensor
Technology Ltd: Research at the University of Manchester has
demonstrated servo systems with vastly improved dynamics with the most
challenging of loads. The key to the increased performance is a torque
transducer from Sensor Technology employing Surface Acoustic Wave (SAW)
techniques to deliver high-bandwidth, non-contact solution. The ease of
set-up of modern servo drive systems, combined with steadily reducing
costs, has made servo control an attractive proposition across the
spread of motion control applications in a wide range of industries.
Despite the developments in inverter technology which promise near-servo
performance, in the most demanding applications requiring the fastest
response and the most precise control of position, velocity and torque
only true servo systems can cut the mustard. The ease of access to servo
technology, and the steadily increasing capabilities of servo
controllers, has seen machine designs pushing the boundaries ever
further, with faster system response becoming an increasingly common
industrial requirement. With a perfect load, this would not represent a
problem. But no load is perfect. Practical mechanical drive systems can
be complex, incorporating several non-still interconnecting shafts and
elastic couplings, all characterised by ... |

UAV takes fast track to altitude |
| |
|
Sensor Technology Ltd: Development of a vertical take-off and
landing unmanned aerial vehicle is nearing completion, thanks in part to
a non-contact digital torque sensor, TorqSense, which proved the only
viable option for use on the test rig. The low-cost, flexible search and
surveillance unmanned aerial vehicle (UAV) is intended for military,
homeland security, policing and environmental monitoring. It is rugged,
immediately deployable and can be launched from the ground, ship or even
moving vehicles. The vectored-thrust UAV platform is suitable for any
situation requiring safe aerial viewing or sensor measurement. It is
being developed by SELEX Sensors and Airborne Systems (S&AS), a
Finmeccanica company. “The TorqSense technology has been one of the key
enablers for the development and implementation of the novel propulsion
system on the Damselfy UAV” said Mark Agnew, Selex’s Chief Engineer for
UAV Systems. Leading the project is Ashley Bryant, who started out
wanting to build a flyable scale-model replica of the vertical take off
Harrier jump jet, but quickly saw the potential for a professional UAV.
Using a jet engine was out of the question, a ‘cold fan’ solution the
only practical option. “A jet engine combusts fuel to turn its turbine
and create thrust,” he explains. “Our cold fan is driven, via a drive
shaft, by a miniscule but powerful two-stroke engine. Developing this
technology required us to build a unique test rig, with an in-line
torque sensor ... |
