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

Description

Platinum Resistance Thermometers, available with a 3.0mm, 4.5mm, 6.0mm or 8.0mm diameter 316 stainless steel probe, and as a 2, 3 or 4-wire configuration.

The PMHI sensor is terminated with an IP67 rated miniature die cast alloy terminal head which has a 16mm x 1.5mm (M16) cable entry. Inside the head is a ceramic terminal block which makes connections to the extension cables very easy. Supplied as standard with a brass compression fitting attached to the terminal head (stainless steel options available on request).

The PMHI 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.

This product can be supplied with a calibration certificate.
