Position Sensor
Industrial Tachometers
for harsh environments
for measurements with or without contact
The Positape WB17KT series of stainless steel tape
sensors come with measurement ranges of
3,500mm, 6,500mm and
10,000mm. The robust
sensor features a very
compact housing specifically designed for rugged
and harsh environments.
Building upon this proven
technology, the series replaces the measurement
cable with a thin, highly flexible stainless steel band. The
WB17KT operates in a similar manner as a tape measure. Due to the smooth surfaces of the tape, the risk of
ice build up is reduced and an optional brush is available to wipe off debris from the tape as it is being retracted. The WB17KT series is available with analog 010V, 4-20mA or 1kOhm outputs. The sensor also comes
with either absolute digital SSI or CAN-Bus outputs. The
electrical connection can be made with either a M12 or
D8 connector.
The C.A 1725 and C.A 1727 offer a range
of measurement possibilities, with or
without contact. Measurement by photoreflection for no-contact measurement: a
reflective strip is positioned on the part
to be tested. The optical sensor avoids external interference and the active, modulated infrared beam guarantees true
measurements. For traditional contact
measurement, a mechanical adapter (cylinder, cone or calibrated wheel) converts the
rotation speed into pulses which are then
measured by the tachometer. The third possibility is provided by an external input
which can be used to connect the tachometers to a large
number of sensors delivering voltage signals. Both
models are equipped with MIN, MAX and measurementsmoothing functions. In addition, the C.A 1727 offers
user-definable alarm thresholds and the possibility of
recording and processing the data via its USB output with
the TACHOGRAPH software. The digital display is a
genuine control panel showing a 42-segment bargraph
and all the useful information.

Ultrasonic Sensor
Special Winding Motors
detects clear or coloured containers
operating at 50Hz - 400V & 60Hz - 480V
The U-Gage M25U has
25mm smooth stainless
steel barrel sealed to IP69K.
It withstands the heat and
high wash pressures of
sanitary operations. It is
the first ultrasonic sensor
with both hygienic design
using FDA-approved materials and IP69K rating for use in harsh environments.
These features assure reliable performance in bottling
plants and other demanding food, beverage and pharmaceutical applications. The sensor operates over a wide temperature range of –20 to 70°C and can withstand high
pressure sprays at up to 100 bar/10MP and harsh chemicals
for cleaning. It uses stainless steel transducers to create
and receive the ultrasonic signal instead of traditional ceramic transducers that cannot survive in washdown conditions. For easy cleaning and disinfecting, the smooth 316 stainless steel housing has no threading, gaps or seams to trap
contaminants. ECOLAB certification is pending. The sensor
detects presence or absence of clear or coloured containers during sanitizing or other clean-in-place procedures.
The powers and the operating values of three phase asynchronous electrical
motors are valid under the
conditions that it is in continuous running (S1) and
the nominal voltage is
400V ±%5, the frequency
is 50Hz, the ambient temperature is a maximum of 40°C and the attitude of
the place of usage is maximum 1,000mt above the sea
level. The motors are convenient for Delta 230V / Y 400V
connection under 50Hz frequency for powers of 3kW
and less. Where it is convenient for Delta 400V / Y
690V connection for powers of 4 kW and more. The motors were designed to operate with values 50Hz - 400V
and 60Hz - 480V. Except from the standard applications,
the company has also production of motors which
could run under desired voltage and frequency. Except from these, for preventing the humidity in the windings of the motor, water condensation can be prevented by keeping the temperature steady inside the body by optional heater application.

BREATHERS ARE
IMMERSION-PROOF
The renowned Brownell range of breathers prevents
pressure or vacuum build-up in equipment and
containers. They allow ‘breathing’ but can withstand
driving rain or event total immersion in water up to 1m.
Many electronic products produce heat which can cause a
build-up of pressure within their enclosure, and without
adequate venting and breathing the lightweight material could
fracture.
But the lightweight
materials used in the
manufacture of specialist
electronic products often
give designers a dilemma of
either restricting the
applications or increasing the
strength of the enclosure.
Brownell’s immersionproof breathers, made from
engineering plastics, can pass high flow rates of air resulting
from rapid changes in temperature and pressure.
They can be screwed in place or mounted using a locking
nut that is supplied, or can be mounted with desiccator tubes
to remove moisture vapour.

Micro-dosing Valve
Infrared Thermometer
enables high-precision dosing
IP65, single-piece
The micro-dosing valve integrates a completely new constructive concept.
The solution consisting of dosing unit,
step motor and control system is therefore able to dose various media with different viscosities and also with solids contents sequentially in a highly precise way (repeating accuracy almost 100 percent). Also regarding the
purity of the medium to be dosed the dosing valve denies no wishes. The medium is lead through a highly clean
channel by plate cams so that the chemical properties
of the medium to be dosed remain the same both in front
of and also behind the valve. Because of the above-mentioned characteristics the valve can be cleaned quickly
and thoroughly when it is installed. The micro-dosing
valve is recommended to be used in the paper, pharmaceutical and chemicals industry as well as for the areas medical technology, automotive, mechanical engineering and laboratory technology.
Designed for easy
integration, the CM
sensor can easily replace traditional
contact probes with
a J-type or K-type
thermocouple output, or with a userscaleable 0-5 volt output, if the application is susceptible to noise. The Raytek CM includes precision, high-resolution silicon optics. A RS232 digital interface allows
the user to configure all programmable sensor variables
via the Multidrop software. These include a 24VDC
alarm output triggered by target temperature or head
ambient temperature; peak hold, valley hold or variable
averaging signal processing; adjustable target emissivity settings; and adjustable window transmissivity setting. A built-in sensor health LED provides a convenient on-line indicator of the sensor's operating status
and aids in troubleshooting initial sensor set up. The Raytek
CM sensor is designed to measure target temperatures
ranging from -20 to 500°C. Its onboard electronics are
protected by a rugged IP65 stainless steel housing.
