OPTITEMP TRA-F23 – Standard version

Resistance (RTD) temperature assembly OPTITEMP TRA-F23 – Standard version

The OPTITEMP TRA-F23 is a flanged RTD sensor assembly with a reduced welded multipart thermowell (based on form 2F). The industrial temperature assembly for standard applications is suitable for temperature measurement of solids, 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-F23 is designed to operate up to +600°C / +1100°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.
