The OPTITEMP TRA-TF56 is a flanged RTD sensor assembly with a tapered barstock thermowell. The temperature assembly for advanced requirements is used when the strength of welded multipart thermowells is not sufficient and a high mechanical stress resistance of the thermowell is required. It is therefore particularly suitable for temperature measurement in pipes, tanks or reactors at higher flow velocities and pressures (e.g. in the petrochemical or oil and gas industry). The RTD is designed to operate up to +600°C / +1112°F. The particular advantage of this sensor type is that its wetted parts can be coated (e.g. with PTFE), making it resistant to aggressive media.
The OPTITEMP TRA-TF56 features a modular design with a threaded 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.
