Description
A platinum resistor is built into the temperature sensor. Changes in
temperature are refl ected by changes in the electrical resistance, so
that measuring the value of the resistance gives an analogue expres-
sion for the actual temperature.
The Pt100 element has a resistance of 100 Ohms at 0°C and a well-
documented working curve (DIN/EN/IEC 60751) within the nominal
working range.
The sensors are used in a wide range of applications within the
marine, industrial, energy and food sectors.
The Pt100 sensor fi ts as an insert in sensor tubes with an internal
diameter of 6 mm such as the CombiTemp tem pe ra tu re measuring
system.
Air sensors are used without sensor pockets to ensure fast response
time.

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.
