Resistance (RTD) temperature assembly OPTITEMP TRA-TS37 – Standard version

The OPTITEMP TRA-TS37 is a threaded RTD sensor assembly with a straight barstock thermowell (DIN form 9). The temperature assembly for advanced requirements is particularly suitable for use in pipes, tanks or reactors where a higher mechanical stress resistance of the thermowell is required (e.g. petrochemical or oil and gas applications). It is designed for temperature measurement of liquids and gases up to +600°C / +1100°F.

The OPTITEMP TRA-TS37 features a modular design with a union nut 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 resistance temperature device can be combined with most thermowells. It is available with ATEX and IECEx approvals.
