Shroud temperature monitoring system

Discover the patented temperature sensor for monitoring seal-less magnetic drive pumps with a metal shroud.

Functions and applications

  • Measures surface temperature of the shroud between magnet rotor and magnetic coupling.
  • Allows the pump to be switched off to prevent consequential damage.
  • Detects impermissible temperature rise inside the pump.
  • Detects impermissible dry running.
  • Extremely fast reaction time.
  • Transformer generates a signal of 4-20 mA.
  • Inherently safe use in areas with risk of explosion.


  • Rugged design with thermo-electric element in fixed casing.
  • Cables on the thermo-electric element run through a protective tube welded on the shroud into the connection box.
  • Protective tube made of stainless steel.
  • Various connection heads available.
  • Transmitter available in different versions.
