The OPTITEMP TRA-W50 is a cable sensor (RTD) with M6 or M8 bolt connection. The temperature sensor is suitable for measuring bearing temperature in moving, oscillating machinery. It features a Pt100 or Pt1000 measuring element that is placed in the tip of the bolt filled with heat transfer compound for fast response times and vibration resistant operation. The measuring range of the RTD is -50…+200°C / -58…+390°F. The OPTITEMP TRA-W50 comes with PTFE, PVC or silicone insulated connecting cable. It can be provided with free flying wires for installation in applications where connection terminals already exist.
