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.

Technical parameters of the Pt100 sensor

Temperature resistance of cable: -100 to +250 °C

Recommended distance of the cable from the power cables:

up to 0,5 m (according to the nature of interference)

Connection of Pt100 to Papago

The sensor is connected to Papago 2PT ETH using four wires. Individual colours are connected to the following terminals:

  • Blue ... D+
  • Red ... S+
  • White ... S-
  • Black ... D-

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.
