Details

The pyrometer IS 50-LO/GL is specially designed for the glass industry. It is used for the temperature measurement of glass in tank, working end, forehearth and feeder. Additional applications are the measurement of brickworks in regenerator and tank.

Using a robust fiber optic cable (length up to 30 m) enables the use of the instrument in an ambient temperature up to 250 °C without cooling.

The IS 50-LO/GL is a digital pyrometer in two wire technique. This technique combines the high accuracy of the digital signal processing with the simple connection and operating with two wires.

The emissivity is exactly adjustable at the device, additionally any sub range and the response time via service interface. The instrument is equipped with a test function to check the correct connection.

Applications: specially designed for the glass industry

  • Glass temperature measurement
    • in forehearth
    • in feeder
    • in tank,
  • Temperature measurement of brickworks
    • tank side walls
    • tank roof
    • in regenerator
