The OPTITEMP TRA-S22 is a threaded RTD sensor assembly with a reduced welded multipart thermowell (based on form 2G) and neck tube. The industrial temperature assembly for standard applications is suitable for temperature measurement of liquids and gases where a fast response time is required. It can be used in pipes and tanks at low to medium pressures and flow velocities. The OPTITEMP TRA-S22 is designed to operate up to +600°C / +1112°F.
