Temperature Sensors

The Rotronic Monitoring System can work with various temperature sensors. However, mainly Pt100 and NTC sensors.

A Pt100 is a RTD (Resistance Temperature Detector) and an NTC (Negative Temperature Coefficient) is a thermistor.

Thermistor overview:

RTD overview:

• Are more accurate, linear and stable than thermocouples,
• Extension wires can be copper wires,
• More expensive than thermocouples,
• Need a known excitation current suitable for the sensor type,
• More fragile...

Rotronic recommend using Pt100 sensors for all applications where accuracy is critical.

Rotronic offer both Pt100 and NTC dataloggers.

• Pt100: RMS-LOG-T30-L & RMS-LOG-T30-868/915.
• NTC: RMS-MLOG-T10-868/915.

Here is an overview of the various sensors:

• Temperature Pt100.
• Temperature NTC.
