Stick-in sensors

Stainless-steel stick-in sensor, Pt100, thermocouple


Temperature sensor T.4.1.

  • Compact and robust design
  • Ideal for shipbuilding, thanks to their construction and approvals
  • Simple assembly via compression fitting
  • Pt100 measuring element or type K or type J thermocouple; two thermocouples per sensor or two Pt100 measuring elements available as an option
  • Available in various immersion depths
  • 90° cable outlet
  • Increased measuring range up to 800 °C
  • Available in various cable lengths


Temperature sensors of type T.4.-1 are stainless-steel stick-in sensors with a Pt100 measuring element or a thermocouple. The sensors are also available with two Pt100 or two thermal measuring elements with 2-wire technology. They have a 90° cable outlet at the side with a fixed cable end. These are inserted into a protection tube and secured via a compression fitting.
