Configuration
6.2.7.1 Sensor
Three types of sensor inputs are being accepted by the chart recorder.
6.2.7.1.1 RTD
It is Resistance Temperature Sensor. The sensor name is PT100.
A platinum resistance temperature detector (RTD) is a device with a typical resistance of 100 Ω at 0°C.
It consists of a thin film of platinum on a plastic film. Its resistance varies with temperature and it can
typically measure temperatures up to 750 °C. The relationship between resistance and temperature
is relatively linear as shown below for a sample 100 Ω RTD.

6.2.7.1.2 Thermocouple
Recorder accepts as listed under.
❖ TC-J
It is made up of iron (+ve electrode) & constantan (-ve electrode). It operates over the
temperature range of (-200) to (1200) C temperature. Its sensitivity is 50 uV/C.
❖ TC-K
It is made up of chromel (+ve electrode) & alumel (-ve electrode). It operates over the
temperature range of (-200) to (1372) C temperature. Its sensitivity is 41 uV/C.
❖ TC-C
It is made up of tungsten (+ve electrode) & rhenium (-ve electrode). It operates over the
temperature range of (0) to (2300) C temperature. Its sensitivity is 46 uV/C.
