Mineral Insulated RTD (Pt100/Pt1000) Sensor with Standard Head

Description

Platinum Resistance Thermometers, available with a 4.5mm, 6.0mm or 8.0mm diameter 316 stainless steel probe.

The PSHI sensor is terminated with an IP67 rated standard (heavy duty) die cast alloy terminal head which has a 20mm x 1.5mm (M20) cable entry. Inside the head is a ceramic terminal block which makes the connections to the extension cables very easy.

Available as Simplex or Duplex in 2, 3 or 4-wire configurations. A 4~20mA transmitter can be mounted in the terminal head if required. Supplied as standard with a brass compression fitting attached to the terminal head (stainless steel options available on request).

The PSHI mineral insulated sensor is supplied with a 316 Stainless Steel sheath and is suitable for use over a wider temperature range: -75°C to +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.

Suitable for use between -75°C and +500°C.

This product can be supplied with a calibration certificate.
