OPTITEMP TRA-P10 – Standard version

Resistance (RTD) temperature assembly OPTITEMP TRA-P10 – Standard version

The OPTITEMP TRA-P10 is a plug-in RTD sensor assembly with a straight welded multipart thermowell (based on form 2). The industrial temperature assembly is suitable for temperature measurement of liquids and gases. It is designed to operate up to +600°C / +1100°F.

The OPTITEMP TRA-P10 can be used in pipes and tanks, at low to medium pressures and flow velocities. It is very flexible to use since the decision as to the required insertion depth is only necessary immediately prior to installation. The RTD is available with ATEX and IECEx approvals.
