"A simple fibre-optic, two-wire, loop powered thermometer with 4 to 20mA output. Specifically designed to improve process control in the glass industry.

Offering accurate, high resolution and reliable temperature measurements up to 1650°C (3000°F), the FG thermometer enables precise control of process temperatures in the glass industry.

A simple, cost-effective alternative to tri level thermocouples for some zones measuring bulk glass temperature which is independent of glass level. FG’s highly stable temperature measurement is available in five temperature spans for maximum cross-application flexibility.

Containing AMETEK Land’s market-leading infrared measurement within an advanced optic head, FG is easily installed in the furnace and linked by multi core fibre-optic light guide to a remotely located signal processor unit.

FG’s flexible design means it not only can monitor and control glass or refractory temperature in the forehearth, but also in the regenerator, tank and refinery, as well as other spot measurements required for glass production."
