 Thermatel® TG1 Two-Wire IS Thermal Dispersion Switch   Printer Friendly Version
Thermatel TG1 provides a two-wire, intrinsically safe circuit between the probe and remote din rail enclosure. The switch is suitable for liquid or gas flow, level, or interface detection using the proven thermal dispersion technology.
Operating Principle Features Options Downloads Approvals
 
Using thermal dispersion technology, the TG1 detects heat transfer which reduces the temperature difference between the sensors. The electronics compare the electrical signal from the sensor against the set point and provide a relay actuation.

 

  • LEDs provide visual flow indication
  • 24 VDC input power
  • mA output signal for diagnostics and repeatable flow/level indication
  • Adjustable set point and time delay
  • SPDT Alarm relay
   

  • Probe materials of construction
  • Probe process connections
  • Probe length
  • Low flow body for very low flow rate detection
