Fabricated 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 PMH 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 PMH 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.

This product can be supplied with a calibration certificate.
