Fibroptic Model FG thermometer  
Non contact two-wire Fibroptic thermometer for high temperatures.

Fibroptic Model FG operates at short wavelengths to provide maximum accuracy of measurement for high temperature applications between 980 and 1650°C/1800 and 3000°F.

A 4 to 20mA linear output is provided directly from the thermometer for connection to temperature readout, recording or control equipment. The only requirement is a suitable power supply.

The same two wires that provide the power to the thermometer also carry the temperature signal out.

Fibroptic Model FG is a rugged thermometer in which an optic head is linked by a fibre optics light guide to an uncooled body, housing a signal processing unit, located remotely from the high ambient temperatures at the optic head.

The use of flexible, high temperature rated fibre optics light guide and optic head allows measurement of targets which may be inaccessible to conventional thermometers.

Typical Applications
