High Temperature Measurement in the Glass Industry Fibre-optic Model FG Two-wire Fibre-optic Thermometer The Land Fibre-optic Model FG radiation thermometer is a fibre optics based 2-wire temperature sensor which has been specifically designed to solve measurement problems and improve control of process temperatures in the glass industry. Model FG is primarily intended for monitoring and controlling glass or refractory temperatures in the forehearth, but also in the regenerator, tank and refiner. It can be used to monitor and safeguard vulnerable refractory materials such as the crown, detect possible firing imbalance at the port arch, for example, and to give improved control of bulk glass temperatures. Thermocouple Replacement Model FG fulfils the industry’s need for a simple, cost effective alternative to other types of radiation thermometers which normally require water cooling. It also readily permits upgrade from existing thermocouple installations. Features & Benefits • Accurate and reliable measurement up to 1650°C/3000°F – ideally suited to control of process temperatures in the glass industry • 2-wire 4-20mA current loop system – ensures simple installation • 200°C ambient temperature limit on optic head – minimal services and no water cooling required • Built-in test facility - ensure optimal performance • No on-line calibration required – Long term, drift free operation • Calibration traceable to National Standards, backed by ISO9001 Quality Management System – measurement accuracy assured Several models are available with measurement spans to suit the particular application. However, it can also be used for cost effective temperature measurement in a range of other applications.

Measurement Ranges Easy Installation O A versatile adjustable mounting assembly, complete with quick release adapter and air purge, provides ease of installation and removal for inspection purposes. Signal Processing G The signal processor unit is located remotely from the high ambient temperatures encountered at the optic head, linked by a sealed 6.1m/20ft long fibre optics light guide eliminating the need for water cooling. The processor provides high accuracy linearisation of the detector signal, adjustable emissivity compensation, a self test function and a low drift 4-20mA output...
