Both the usual and the hygienic standard uses a Pt100- Platinum RTD (Resistance Temperature Detector) with a resistance of 100 ohms at 0 degrees Celsius whose resistance changes with change in temperature. The purpose of employing this sensor element is to measure, monitor, and control of process temperatures in general and hygienic processes as well.

The Thermophant TTR35 takes up a DC voltage version for its output: It can take up one PNP switch output, or two PNP switch outputs, or a combination of two PNP switch outputs or one PNP switch output and 4-20 mA output. To summarise, the device is capable of having more than one output.

In general, E-code are for errors and W-code are for warnings. In the event of an error message, the measured value is uncertain while the value can be reliable during a warning message. Some general error codes are E011- Device configuration faulty, E012- Error in measurement, E019- Undervoltage/Overvoltage, E021- Error in RAM, and E044- Fluctuating output current. Similarly, some warning messages are W202- Temperature outside the sensor range, W210- Configuration modified, W212- Sensor signal outside the permitted range, and W250- Number of switch cycles exceeded.
