Metal Sheathed Heavy Duty Thermocouple Sensor with Standard Head

Product Code: THD

Commonly used in applications where a robust, heavy duty construction and improved chemical resistance are necessary, such as incinerators. The THD sensors are mechanically strong and available with 12.7mm, 15.8mm and 21.3mm probe diameters, in lengths to suit your application requirements.

As standard they are supplied with an IP67 rated heavy duty die cast alloy terminal head (M20 x 1.5mm cable entry thread). They have a robust 6.0mm diameter, mineral insulated, metal sheathed spring loaded insert which is mounted into the head via two spring-loaded screws. The spring loading ensures a good contact with the outer sheath which improves the speed of response and performance.

The screw top lid has a robust chain ensuring it remains attached to the head. A ceramic terminal block inside the head makes connections to the extension cable very simple. The sensor can also be supplied with a linearised 4~20mA transmitter which can be pre-ranged to suit your requirements.
