54-105 Thermatel TG1

Thermatel TG1
Thermal Dispersion Switch
DESCRIPTION
Thermatel TG1 is a two-wire, intrinsically safe switch for
liquid or gas flow, level, or interface detection using the
proven thermal dispersion technology.
The switch consists of a DIN rail mounted electronics
unit and a remote sensor with separation of up to 1650
feet (500 meters)
Applications for the TG1 include low flow detection,
high temperature operation, and high viscosity and
coating applications
