Optical Measurement of gear teeth |
| |
 Profile
scanners (model scanCONTROL 2800-25) from Ortenburg-based sensor
specialist Micro-Epsilon are able to generate digital 3D images
of gear teeth and so can be used to measure the run-out characteristics
of gear shafts with plug-in toothing, bevel gears with hypoid toothing
and similar axial components. As gear wheels can warp during
manufacture, the run-out requires inspection. The extent of the
“ovality” and the direction in which it should be adjusted must be
determined for any adjustment of the workpiece. Special measuring
instruments use high-precision laser scanners that enable automatic
adjustment of the workpiece, quickly and precisely. The scanCONTROL
2800-25 laser line scanner with a 25mm measuring range digitises the 3D
structure of the tooth area and so is used for these types of
application. The scanners achieve a measuring rate of up to 256,000
points per second. The sensor can be configured quickly and easily using
the new Configuration Tools ... |

The changeable light spot, ELTROTEC
precise laser proximity with background suppression |
| |
 The
PS1 from ELTROTEC is a laser proximity that due to its adjustable
optic allows for setting an either round or elliptical light spot in
various sizes. Even in fast processes and short cycle times the sensor
is not missing out on a single part: due to the switching frequency of 5
kHz the sensor can be used in assembly and supply systems running at
high speed. PS1 is mainly used for controlling assemblies and presence
of small parts as well as electronic components on printed boards making
high resolution an important feature and allowing detection of parts
from 0.1 mm and up. Compact and easy to install these sensors are
similarly suited for breakage control in machine tools and through the
elliptical light spot adjustment reliably detect structured surfaces
which otherwise might cause problems to small light spots. Easy
adjustment and control as the red light shows a wave-length of 675 nm,
meaning it is visible. The precise detection on point 0.1 mm will be
done by mechanical potentiometer. Sensing range varies from ... |

New low cost laser sensors |
| |
 The
new low cost optoNCDT1302 laser sensor from Micro-Epsilon
replaces the optoNCDT 1300 in the product range. The new sensor will be
on show for the first time at the SPS|IPC|DRIVES exhibition in Nürnberg.
Compared to its predecessor, this model provides a measuring rate of
750Hz and is available for the first time with an RS422 port in addition
to the analogue current / voltage output. The sensor has a trigger and a
teach-in input, which enables the user to individually adjust the
measuring range. Another special feature of the sensor is the integrated
peak evaluation for selection of the first, last or highest peak
measurement. Also new is the Threshold Function for adjustment of the
threshold setting in three stages. The optoNCDT 1302 provides
flexibility via a swivelling cable connector so that the direction of
the cable output can be selected depending on the individual
application. As before, the new series comprises four sensors, which
offer measuring ranges between 5mm and 200mm. Together with the
integrated controller, the very compact design facilitates rapid
mounting and installation in tight spaces. The optoNCDT 1302 is suitable
for all common measurement tasks. Despite its compact dimensions, the
1302 series provides precise measurement results and is therefore ideal
for machine building and system integration. ... |

Measuring laser sensor for distances up
to 4 m |
| |
 Baumer
has recently added the laser distance sensor OADM 250 to its portfolio.
The sensor is based on time of flight technology and covers an operating
distance of 4 m – even on black objects. The OADM 250 complements
Baumer’s broad range of laser distance sensors. Sensors of the same size
working with the triangulation principle reach their limit at distances
of 1 m. This is where the OADM 250 comes in. It is suitable for
applications in which distances between 0.2 m and 4 m have to be
measured. Thanks to a special calibration, the measurement is
independent of the object color and surface properties. The repeat
accuracy (+/- 5 mm), linearity (+/ 20 mm) and short measuring repetition
rate of 10 ms allow precise measurements also on moving objects. The
compact design of the sensor facilitates its integration into the
application, and especially any retro fitting. The integrated standard
alarm output improves the process safety. This output reports if the
sensor cannot interpret the received signal due to too heavy soiling. ... |

2m |
| |
 Measurement
technology company Micro-Epsilon has launched a new laser sensor
with a 1m measuring range. The optoNCDT 1710-1000 sensor has a measuring
range that starts from a distance of one meter from the sensor, so
displacement can be measured at a distance of 2m from the sensor. The
sensor comes with an integrated controller in a compact 200mm x 83mm x
48mm housing. The diameter of the light spot is constant across the
complete beam path. With a measuring rate of 2.5kHz, the sensor is
technically superior to existing alternative sensors on the market,
providing 100µm resolution without averaging. 4 … 20 mA, 0 … 10V, RS422
or USB outputs are available. The optoNCDT 1710-1000 is used for
measurement objects that have a high degree of freedom or movement.
Other potential applications are in harsh ambient conditions, where the
sensor has to measure onto the object from a safe distance or if the
target is in a vacuum. The sensor also ... |

interface |
| |
|
Baumer:
The Series 12 family of laser distance sensors are now also available
with the serial interfaces RS232 and RS485. The laser distance sensors
OADM 13 have a convincingly compact housing (13.4 x 40 x 48.2 mm) and a
measuring distance of up to 550 mm. The triangulation method combined
with the precise optics and an intelligent signal evaluation allows
resolutions of up to 10 µm at a measuring rate of 900 µs. The sensors
are available with measuring ranges of 300 and 500 mm. Depending on the
application, the sensors are offered with dot shaped or linear laser
beams. Using the interface, the current data cannot only be recalled and
transmitted continuously, but it can also be e.g. gauged or archived in
a hold register where it can be accessed later. In case operational
reasons call for a temporary shut down of the laser, the correspondent
order can be transmitted through the interface. Thanks to the compact
housing, the sensor can ... |

Compact profile sensor for defined
measurement tasks |
| |
|
Micro-Epsilon’s
range of compact profile scanners has been expanded with the new
scanCONTROL 2710 sensor. This sensor series has an extremely compact
housing with integrated controller. The scanCONTROL 2710 provides a
complete solution for simple measurement tasks. Angles, steps and
positions can be recognised and tracked. The same is also possible for
profiles, including adhesive beads, weld seams, grooves and gaps. After
the sensor has been configured using the set-up software supplied as
standard, the system runs in standalone mode and can be connected
directly to a controller. Using the integrated controller, the sensor
can perform data acquisition, profile calculations and measured value
generation for the complete measurement field and at full resolution at
100Hz. The compact design of the sensor makes it particularly flexible,
either as a stationary measurement unit or in moving mode on, for
example, a robot. A small output module for DIN rail mounting is
available enabling the conversion of data into common fieldbus systems.
Using this, measurement results can be output using digital or analogue
modules for evaluation or further processing. The profile information is
obtained by using a static laser line, which is projected onto the
target surface. The diffusely reflected light is replicated on a sensor
matrix by a high quality optical system. The sensor calculates profile
data directly from the camera image and the relevant ... |

optoNCDT1402 laser sensor from Micro-Epsilon |
| |
|
The
new optoNCDT1402 laser sensor from Micro-Epsilon replaces the
company’s previous optoNCDT 1401 product. The new sensor provides
improved performance and extreme flexibility. This flexibility comes
from a brand new Teach-In function, which can be used to limit or change
the measuring range for each application. In this way, both the
resolution and the linearity of the sensor in the pre-set measuring
range can be significantly improved. This is of particular benefit in
applications where only a small measuring range but high performance is
required. The flexibility of the optoNCDT 1402 is further enhanced by an
integrated swivelling cable connector, which can be used to change the
direction of the cable output to suit the individual application. By
utilising a CMOS sensor, the optoNCDT 1402 has an increased measuring
rate of 1.5kHz making it suitable for rapid processes. An RS422 digital
interface is provided, as well as analogue current / voltage output. As
before, the new series comprises seven sensors, which have measuring
ranges between 5mm and 250mm. Together with the integrated controller,
the very compact design makes mounting faster and easier and
installation is possible in restricted spaces. Due to its very
effective, real time compensation process for the changing reflection
characteristics of different target surfaces, the optoNCDT 1402 sensor
is universally ... |

|
Micro-Epsilon
has launched a brand new system for the geometrical inspection of ingots
called “dimensionCONTROL 8260 for Ingots”. In just a few minutes, the
system can inspect the surface of the ingots using several laser optical
sensors (line scanners), which automatically measure the side lengths,
phase lengths, angles, diagonal lengths and planarity of the side areas.
The automatic measuring system compares target data with actual measured
values and then classifies the ingot accordingly. The system calibrates
itself automatically to the common ingot sizes of 125mm x 125mm, 156mm x
156mm and 210mm x 210mm. Ingot lengths of up to 2,500mm can be measured.
Calibration of each respective ingot is carried out by using integrated
master parts or components. The identification of any ingot defects is
performed either automatically with a marking unit or manually. The
weight of the ingot also plays a key role in determining the production
yield. Therefore, the system can also be supplied with an integrated
load cell. The sensor system and base plate traverse along the test item
during the measurement process. ... |

Special
sensors for optical distance measurement of direct reflecting materials
are now available from Micro-Epsilon. Designated as the optoNCDT
1700DR, this new series expands the manufacturer’s already extensive
sensor family. Three sensors with the measuring ranges of 2mm, 10mm and
20mm are designed specifically for use with polished metals, glass or
chrome-plated products. The high measuring rate of 2.5kHz and the
maximum resolution of 0.1µm make precise measurement of the desired
targets possible. The reflected laser beam is guided into the receiving
array by tilting the sensor and is then directly converted into an
electrical signal by the integrated controller. The design is identical
to the successful optoNCDT 1700 standard series. As well as the
integrated controller, the series also incorporates a foil keypad
directly on the sensor, whereby adjustments without configuration
software are possible. The comprehensive ILD Tool 1700 software, which
also makes a measured value display possible, is included as standard
for more simplified operation of the sensor at a computer. A different

Laser
micrometers are now available from Micro-Epsilon that provide
more than double the existing measuring range. The two new models are
called optoCONTROL 1202-75 and optoCONTROL 1202-100. The measuring range
of these two new devices are 75mm and 100mm respectively. The sensors
are therefore ideally suited to applications where previously two laser
micrometers had to be used, since the measuring range of one sensor was
insufficient. An additional controller unit is not required for the two
new models Nevertheless, the transmitter and receiver unit has a height
of just 30mm. For both measuring instruments, the transmitter is
separate from the receiver; therefore, the measuring instrument is
extremely flexible for mounting. The measuring device is fully digital
with a CCD array as the receiver. In this way, a very high, independent
linearity of 0.2% is possible. Easy-to-use configuration software is
included as standard, which enables the measuring device to be easily
adjusted to suit the application. For simplified commissioning, the
target value can be adjusted, for example, by using potentiometers on
the back of the device to define Teach-In or switching limits. The

Micro
Epsilon has extended its product range with new laser sensors. In
addition to the existing time-of-flight sensors there are four new
complementary models. Under the names optoNCDT ILR 1181, 1182, 1183 and
1191, these sensors provide new approaches to solving automation tasks.
The 80 Series functions according to the phase comparison principle,
whereby a precise distance measurement is possible. They achieve a
measuring range of 30m for use on diffuse reflecting surfaces and 150m
when using a special reflector, which guides the laser pulse back into
the optical system for large measuring distances. The optoNCDT ILR 1191
operates according to the “Time-of-Flight” principle and achieves a
measuring range of 3,000m with a reflector; a measuring range of 300m is
possible without using the reflector. With a linearity of between ±3mm
and ±5mm or ±20mm to ±0mm for the 1191 series and a repeat accuracy of
less than 0.5mm, these sensors are ideal for precision measurement

The
HRTL 96B laser light scanner from Leuze electronic for horizontal
positioning, overshoot control, safeguarding the operation of cranes,
compartment occupation checks in intralogistics systems. The multitalent
is especially well suited for positioning tasks and reliable object
detection. It is mounted on the high-bay storage device for safely
positioning pallets on shelf racks in automatically operated, single-,
double- or multi-depth storage systems. With its very good b/w detection
thresholds, the scanner can determine whether a compartment is occupied.
It works on the principle of pulse propagation time measurement. As a
result, other light sources, far and near interfering contours, rounded
shelf edges and different surface colours or materials—such as
reflecting pallet foils and different, even dynamic, backgrounds, like
passing storage and retrieval units for high-bay warehouses—are no
problem for the scanner. Thanks to its large detection range from 50 to
6000 mm, the scanner replaces the complex, mechanical overshoot controls
on the shelves by inspecting the position of the pallet in the shelf
compartment and its protrusion during the bring/fetch process. This
increases process reliability considerably and reduces the work and
costs in assembling the steel construction. The HRTL 96B laser light

Rubber thickness measurement using Acuity
laser sensors |
| |
|
Acuity laser sensors are used throughout the tire and rubber
manufacturing industries. Rubber sheet manufacturers need online
thickness measurements for Quality Control and system control feedback
loops. Rubber presents several challenges for non-contact metrology
equipment with its low surface reflectivity, dirty measuring
environments and elevated material temperatures. System integrators for
the tire and rubber industry demand reliable, non-contact measuring
devices to minimize downtime and scrap material production. Rubber
conveyor belt manufacturers use Acuity laser displacement sensors to
measure the thickness of black rubber sheet in a calendaring process.
After numerous trials and worldwide installations the AccuRange 700-4
sensor model was chosen to replace other equipment which failed to meet
accuracy and speed requirements. The AR700 sensor is extremely durable
and meets the environmental requirements for this industrial
application. During calendaring and rubber processing, the surface of
the rubber sheet may be very shiny and very black, creating challenging
conditions where little light can be reflected back to a sensor’s
detector. Acuity installs an upgraded laser diode in their rubber
thickness measurement sensors, bringing 5 mW of laser power (standard is
1 mW) to get a stronger return signal off the dark surface. The
increased power with Acuity’s patented optics, results in excellent
sensitivity on the rubber sheet and fast measurement speeds. ... |

Laser Distance Meter LDM301, Measuring
distance and speed without a reflector |
| |
|
Jenoptik:
The LDM301 laser distance meter measures distance and speed values in a
non-contact fashion, also without a reflector. Taking only a short time
to measure, it enables distance measurement to or from moving objects.
The laser pulse’s time-of-flight measurement principle is particularly
suitable where long distances have to be measured or for operation in
harsh industrial environments. Of compact design shape, simple setup and
configured with standard interfacing facilities, the LDM301 can easily
be installed and commissioned. For interfacing, RS232, RS422, SSI and
Profibus are available. Standard LDM301 delivery includes heating, a
status display and a sighting device. A modular setup allows for easy
complementation with accessories or special models for particular
applications. ... |
