New sensor generation for 3-dimensional object measurement
Wenglor has developed
sensors that can scan and
evaluate objects in 3 dimensions.
This generation of 70 models
of the weCat3D Profile Sensors
allows data to be either read out
directly as measured values or
used for rapid further processing
of the point cloud.
3 D calculation of volume is of
great value in industries such as
food, machinery manufacturing,
woodworking, electronics,
automotive and pharmaceutical
where precise compliance
to weight and geometric
specifications measurements are
demanded.
More than 12 million
measuring points per second.
The weCat3D series works with
a visual field width within a range
of 30 to 1300 mm in the horizontal
X-axis and is capable of detecting
differences in height of just 2.0 µm
within the Z working range at a
rate of 3.6 to 12 million measuring
points per second. Available laser
classes (1, 2M, 3R, 3B) and two
selectable types of light (red, blue)
result in a diverse product portfolio
of more than 70 models.
Two performance classes and a
thousand possibilities
With a weight of just 300 g and
a space-saving housing of 90 x
36 x 64 mm), the model weCat3D
MLSL scans as many as 3.6 million
measuring points/sec, has an
output range of up to 4000 Hz, as
well as a resolution of down to 22
µm in visual field width X and down
to 3.3 µm in working distance Z.
The model weCat3D MLWL
scans up to 12 million measuring
points/sec, has an output rate of up
to 6000 Hz, visual field widths from
30 to 1300 mm and high resolution
down to 17 µm in visual field width
X and down to 2.0 µm in working
distance Z.
Due to this extremely high
resolution in the Z and X directions,
the sensors can detect the smallest
components in the micron range
such as those used in PCB assembly.
The special algorithms allow
the sensors to generate powerful
measuring signals and top quality
profile data that is not even
impaired by glossy, reflective
surfaces such as metals.
The high dynamic range
ensures that objects can be
precisely measured almost
independent of colour and
brightness.

Controllable single-use diaphragm valve
Introducing the world’s first
controllable single-use
diaphragm valve, the GEMÜ
SUMONDO. The product range
now comprises a manually
operated version alongside a
pneumatically operated solution.
The trend towards simplified
upstream and downstream
plant designs and the
effective prevention of crosscontamination
risks means that
single-use disposable technology
is becoming an increasingly
high-profile and important field
– especially in pharmaceutical
process engineering.
Single-use design is
increasingly being used
particularly in the manufacture
of smaller batch sizes, which are
required, for example, in research
and pilot plants.
GEMÜ SUMONDO links the
valve body and actuator together
using a defined process. After the
application process, only the valve
body is removed, the actuator itself
can be reused repeatedly in the
plant.
The valve body is manufactured
from polypropylene in a cleanroom
and is gamma-sterilizable up to
50 kGy. It isolates the working
medium hermetically from
the environment and from the
actuator via a welded diaphragm.
The internally welded diaphragm
protects the medium from the
environment not only during
operation, but also after removal of
the valve body.
The major advantage of
GEMÜ SUMONDO in comparison
to conventional pinch valves lies
in the precise controllability of
processes. Using a tried and tested
actuator design from conventional
plant engineering, a high degree
of flexibility and reliability can be
achieved.
The manually operated version
has an optical position indicator as
standard.
The new actuator is
manufactured from high-grade
plastic. It is gamma-sterilizable and
washable.
An autoclavable version is
planned for the first six months
of 2017. The process for selecting
the valve body is identical to that
for the pneumatically operated
version.

Versatile and low cost pressure sensors
The tried and tested principle
of a thick-film ceramic
measuring cell ensures great
reliability from the compact
and versatile type SEN-98/-99
pressure sensors .
This pressure sensor meets the
highest of performance demands
by virtue of its robust construction,
overpressure safety properties, as
well as temperature stability and
good reproducibility.
The unit’s overload protection
limit is dependent on the
measurement range, of which
there are 31, running from -1...0
bar to 0...600 bar relative pressure
or from 0…1 to 0…25 bar absolute
pressure. There is a choice of 4...20
mA, 0...5 V or 0...10 V analogue
outputs for signal transmission.
Fast, on the spot information
of the measured pressure is made
possible by the practical AUF
type plug-on displays. Standard
sensors have protection class IP65.
The wetted parts are stainless
steel, ceramic and sealing
material FKM. The SEN-98/-99 is
manufactured with an accuracy of
0.5% as standard, an accuracy of
0.25% is available optionally.
The optimum design opens
up a wide range of applications
for pressure sensors, for example,
hydraulic systems, compressors,
refrigeration industry, welding,
vacuum, water and oil, gases.
