OPTITEMP TCA-TS32 – Standard version

Thermocouple (TC) temperature assembly OPTITEMP TCA-TS32 – Standard version

The OPTITEMP TCA-TS32 is a threaded thermocouple (TC) assembly with a straight welded multipart thermowell (DIN form 5). The temperature assembly for advanced requirements is particularly suitable for use in pipes, tanks or reactors where a high mechanical stress resistance of the thermowell is required (e.g. petrochemical applications). It is designed for temperature measurement of liquids, gases and steam up to +600°C / +1100°F.

The OPTITEMP TCA-TS32 features a modular design with a threaded standard neck tube that can be exchanged easily, even under operating conditions. This makes the temperature assembly very flexible. If it has been damaged from the outside, servicing can be carried out without process shut down. The thermocouple assembly can be combined with most thermowells. It is available with ATEX and IECEx approvals.
