Pt100 compact thermometer, with optional integrated IO-Link and 4–20 mA transmitter, programmable PC

The compact thermometer measures the process temperature using a Pt100 sensor element (Class A, 4-wire). An optional integrated transmitter converts the Pt100 input signal. In the version with integrated electronics, the device automatically detects the connection variant (IO-Link or 4–20 mA).
