OPTITEMP TCA-S11 – Standard version

Thermocouple (TC) temperature assembly OPTITEMP TCA-S11 – Standard version

The OPTITEMP TCA-S11 is a threaded thermocouple (TC) assembly with a straight welded multipart thermowell (based on form 8). The industrial temperature assembly can be screwed directly to the process pipe or tank. It is predominantly used in applications with lower process temperatures up to +150°C / +302°F. The TC sensor is suitable for temperature measurement of liquids and gases, at low to medium pressures and flow velocities. It is available with ATEX and IECEx approvals.
