OPTITEMP TCA-T30 – Standard version

Thermocouple (TC) temperature assembly OPTITEMP TCA-T30 – Standard version

The OPTITEMP TCA-T30 is a weld-in thermocouple (TC) assembly with a tapered barstock thermowell (based on form 4). The temperature assembly for advanced requirements is suitable for applications in pipes, tanks or reactors where flange or thread connections are no longer sufficient (e.g. in steam distribution systems). Its barstock thermowell also features a much higher mechanical stress resistance than welded multipart thermowells, making it particularly useful in applications with higher flow velocities and pressures. The TC is designed for temperature measurement of solids, liquids, gases and steam up to +600°C / +1100°F.

The OPTITEMP TCA-T30 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.
