Screw-in sensors

Stainless-steel screw-in sensor, Pt100, NTC thermistor


Temperature sensor TP61-28

  • Compact and robust design
  • Simple assembly via screw-in thread
  • Pressure spring achieves constant contact with the measuring point
  • Available in various immersion depths
  • Maintenance-free
  • Compatible measuring transducers, limit value switches and analogue indicators available
  • Design available with a Pt100 or an NTC thermistor measuring element


Temperature sensors of type TP61-28 are bearing temperature sensors with a Pt100 measuring element or an NTC thermistor. They have a fixed connection cable with a 90° angled cable outlet. They are screwed into place in a threaded hole. The installation and pressing processes involve a spring and a pressure screw.
