Mineral Insulated Spring Loaded RTD (Pt100/Pt1000) Inserts

Description

The PSLI 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 PSLI mineral insulated sensor is supplied with a 316 Stainless Steel sheath and is suitable for use over a wide temperature range: -75°C and +500°C. The mineral insulated construction allows the sensors to be bent (100mm from tip) and protects the Pt100/Pt1000 element against failure caused by vibration.

This product can be supplied with a calibration certificate.
