Stick-in sensors

Stainless-steel stick-in sensor (B form), Pt100/Pt1000, thermocouple, NTC thermistor


Temperature sensor T.4.3.

  • Compact and robust design (form B connection head)
  • Ideal for shipbuilding, thanks to their construction and approvals
  • Simple assembly via compression fitting
  • Sensor elements: Pt100, Pt1000, NTC thermistor, type K or type J thermocouple; two integrated sensor elements available as an option
  • Increased measuring range up to 800°C
  • Available in various immersion depths
  • Form B connection head
  • Available with integrated measuring amplifier


Temperature sensors of type T.4.-3 are stainless-steel stick-in sensors (form B connection head) for protection tubes and are available with a Pt100/Pt1000 measuring element or a thermocouple, or as an NTC thermistor. The sensors are also available with two Pt100 or two thermal measuring elements with 2-wire technology; the Pt100 measuring element is available with 4-wire technology too. They have a 90° cable outlet at the side and are fitted in protection tubes.
