Thermo Detector TM 3/9 plus

Protect against the risk of fire in industrial processes caused by overheating machinery

Key Benefits

  • Configurable temperature thresholds, pre-alarm threshold, individual dry contacts for slaves
  • Graphical monitoring of the temperature evolution for each probe with GreCon TOUCH control console.
  • Simultaneous temperature monitoring at three different points with eyelet or screw PT1000 probes.
  • Intelligent detector with extended internal monitoring.
  • Real-time detector status via LEDs.

FUNCTIONAL DESCRIPTION

The heat detector TM 3/9 plus is a sensor for the simultaneous detection of temperatures in a maximum of three different areas. The temperature alarm threshold is not a fixed value and can be set in a wide range and may be configured using the GreCon Configurator tool. If the temperature at the measuring point exceeds the configured threshold temperature, then an alarm signal is sent to the control console and this signal is active until the temperature falls below the threshold value.

The detector can be connected to every GreCon control console using a standard three core cable.  A range of flexible mounting adapter options exist to suit any environment. The control console interfaces with the detector for monitoring of ignition sources within the process, configuration of detection parameters and automated check of the detector’s correct function.

Technical Specification

Summary

Temperature monitoring utilizing three contact temperature probes to monitor facilities for mechanical malfunctions. Two configurable alarm thresholds.
