Pt100 sensor in a metal rod. 4 mm in diameter for a temperature range of -90 to +250 °C. Teflon cable 3 m.
This version of the sensor is suitable for basic high-accuracy temperature measurement using Papago 2PT ETH. It can also be used as a Pt100 sensor for other devices and converters that are able to measure temperature from Pt100 sensors.

The sensor is connected to Papago 2PT ETH using four wires. Individual colours are connected to the following terminals:
This picture shows the three most common ways to connect the Pt100 sensor. These are known as two-, three- or four-wire connection. If there is no special reason to connecti it otherwise, we recommend using the four-wire connection.
