The PSL spring loaded RTD inserts are designed to suit new or existing heavy duty thermowells. Most commonly supplied with a 6.0mm outside probe diameter (3.0mm, 4.5mm and 8.0mm also available).

A ceramic terminal block is supplied as standard and can be connected to a terminal head using the spring loaded screws. An optional 4~20mA transmitter can be supplied instead of the ceramic terminal block, if required.

Spring loading ensures that the sensor tip is kept in contact with the tip of the thermowell, which promotes a faster and more reliable response.

The PSL sensor is supplied with a rigid 316 Stainless Steel sheath. Where the design allows, the sensors are powder-filled to protect the element from damage caused by vibration.

Suitable for use between -75°C and +260°C.
