Thermo Detector TM 3/9

Themperature monitoring of bearings and motors

New GRECON TM 3/9 plus

"The best thermal detection performance with simultaneous detection at 3 different points."

The thermal detector TM 3/9 plus allows simultaneous temperature detection at up to three different points. 

A maximum of 3 temperature sensors can be connected to the temperature sensor. 

The TM3/9 plus is used for the preventive monitoring of motor, fan, bearing or bearing temperatures before a fault can occur.

  • Configurable temperature thresholds, pre-alarm threshold, individual dry contacts for servo drives.
  • Graphical monitoring of the temperature evolution for each probe (only GreCon TOUCH control unit).
  • PT1000 probes with eyelet or screw-in probes.
  • Intelligent sensor with internal temperature monitoring.
  • Real-time detector status via LEDs.
  • Remote configuration from the GreCon TOUCH control unit.
