Temperature sensor

For repair or for building your own temperature sensor you need a PT1-100 sensor and a LEMO connector.

The LEMO connector:

• Series: S
• The diameter: 0S (S-Series, diameter 0)
• Insert configuration: 302 (2 pins)

The following LEMO configuration is known to fit:

• Connector: FFA0S302CLA (2.2 to 4.4 mm cable)
• Bend relief: GMA0B035 (3.5 to 3.9 mm cable)

As the PT-100 is connected with only 2 wires, each sensor has to be trimmed with R1001 (offset).
