The OPTITEMP TRA-W20 is a cable sensor (RTD) to be mounted with M3 bolts or with hose clamp. The temperature sensor is suitable for measuring surface temperature on pipes or machinery parts (bearings, gear boxes etc.). Its measuring range is -50…+150°C / -58…+300°F. The RTD features a Pt100 or Pt1000 measuring element that is placed in the measuring tip filled with heat transfer compound for fast response times and vibration resistant operation. The OPTITEMP TRA-W20 comes with ETFE insulated connecting cable. It can be provided with free insulated flying wires for installation in applications where connection terminals already exist.
