Ceramic Sheathed Thermocouple Sensor with Standard Head

Product Code: TCR

Commonly used in high temperature applications where standard metal sheaths cannot withstand the heat.

The ceramic sheath can be supplied as Impervious Aluminous Porcelain (AP) which is suitable for use up to +1400°C, or Impervious Recrystallised Alumina (RA) which is suitable for use up to +1700°C. Both sheaths, being ceramic, are relatively fragile and can be damaged by thermal shock if not pre-heated before insertion into high temperature applications.

Sheaths can be supplied as 10.0mm, 12.0mm, 17.0mm or 20.0 diameter and are glued into a metal support tube onto which the terminal head is connected. The length of the ceramic sensor and support tube can be manufactured to suit the application.

The TCR is supplied with an IP67 rated heavy duty die cast alloy terminal head (M20 x 1.5mm cable entry thread). 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.
