diagnostic information to the Engine Control Unit (ECU) for regeneration
of the DPF. Kavlico’s proprietary ASIC architecture, calibration, and
compensation methods, along with the ceramic capacitive sense element
make these sensors an ideal fit for operation in the exhaust environment
where there is severe vibration and caustic soot and acids. The sensors
feature stainless steel housings and operate on 5 Vdc power supply,
providing a linear amplified analog output of 0.5 to 4.5Vdc proportional
to pressure. The available pressure ranges are (0 - 5.80 and 0 - 7.975
PSIG or 0 - 400 mBar and 0 - 500 mBar). The low power consumption,
humidity tolerant sensors are also EMI/EMC protected, exhibit low

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
(SAWs) ... |

New Texense Strain Gauge Amplifier XN2.1
allows programmable functions without computer |
| |
 Texense International Company, specialist of robust sensors for
embedded measurement introduces a new product. The Texense XN2 is a PCB
analog strain gauge amplifier, with high resolution and high speed, with
offset and gain adjusted by microcontroller. Because of its small size,
the Texense XN2 may be bonded close to the gauges, which will reduce
noise on the signal. When the amplifier is wired to the
strain gauge
bridge, the customer may, with a single VPROG signal (no use of a
computer): * adjust the offset, * adjust the gain by applying an effort
on the part, * start a self training cycle for temperature compensation,
* adjust temperature gain compensation depending on part and gauge
materials, * check the gauge bridge state. The Texense XN2 simplifies
strain gauging because it doesn’t need zeroing, nor temperature
compensation for offset or sensitivity. Just bond 1, 2 or 4 gauges on
the part, wire them to the amplifier and it will do the job ! ... |

Interference-resistant pressure
transmitters |
| |
 Keller
AG für Druckmesstechnik, has implemented a new concept for
temperature compensation and for protection from electromagnetic fields
(EMC) in the recently approved Series 21 Y
pressure transmitters. With
measuring ranges between 2 bar and 1000 bar, the Series 21 Y
transmitters can be used at temperatures ranging from -20 °C to +100 °C
in any industrial application, even in the immediate proximity of
frequency converters. Particular attention has been paid to providing
low-cost calibration that guarantees a maximum Total Error Band of ±1.5
%FS over the entire standard temperature range of -10 °C to +80 °C.
Extensive data collection, such as that required by polynomial
correction schemes, is replaced by a much simpler, costeffective method.
The temperature range is divided into as many as 120 subdivisions, of
1.5 Kelvin each, by an integrated temperature sensor and an additional
digital circuit. The compensation values for TK zero point and TK
amplification for each of these subdivisions are calculated individually
in accordance with a mathematical model and stored in the transmitter.
These values are fed into the analogue signal path during operation
depending on the temperature, without having to reduce the 2 kHz
bandwidth. Series 21 Y transmitters are ... |
