Magnetrol - Thermatel TG1
| General Description |
Magnetrol’s TG1/TG2 switch is the industry’s only two-wire, intrinsically-
safe thermal dispersion switch. The switch consists of a
probe and preamplifier with remote DIN rail electronics. Barriers in
the DIN rail enclosure provide a two-wire, intrinsically-safe circuit to
the probe/preamplifier. |

|
| Product Operation |
The preamplifier converts the temperature difference to a pulse
signal which is super-imposed on the two wires providing power
to the sensor. The DIN rail electronics provide operation control
including set point adjustment, LED indication of flow/level, relay,
fail-safe adjustment, and time delay. A non-linear mA output signal
is available for diagnostics and repeatable flow/level indication. |
