Cable Sensor, Pt100/Pt1000
Sensors with 4-wire silicone cable
for pockets or tubes
4-wire air sensors
Elements in
1/1 DIN B,
1/3 DIN B
and 1/6 DIN B
The sensors can be used with the CombiTemp,
Building Block Temperature Measuring System
Description
A platinum resistor is built into the temperature sensor. Changes in
temperature are reflected by changes in the electrical resistance, so
that measuring the value of the resistance gives an analogue expression for the actual temperature.
The Pt100 element has a resistance of 100 Ohms at 0°C and a welldocumented working curve (DIN/EN/IEC 60751) within the nominal
working range.
The Pt100 sensor fits as an insert in sensor tubes with an internal
diameter of 6 mm such as the CombiTemp temperature measuring
system.
Air sensors are used without sensor pockets to ensure fast response
time.
The sensors are used in a wide range of applications within the
marine, industrial, energy and food sectors.

If a pocket or sensor tube is used, the response time is extended, i.e. the time duration for the sensor to reach the correct temperature when
the temperature of the medium changes suddenly.
