The AS2100 Accurate Distance Sensor is often selected for measuring and controlling the level of molten metal in a furnace. It performs better on hot targets due to the sensor’s phase mixing technology. The sensor also boosts an impressive linearity of +/- 1 mm over the full range of 100 meters and can measure fill levels at speeds up to 250 Hz.
To deal with heat related challenges, Acuity engineers have designed an AS2100 cooling enclosure with a built-in bandpass filter option. The cooled housing enables the sensor to be protected from the hot ambient temperature and the bandpass filter options allows the sensor to perform reliable, accurate measurements on molten metal. The combination of the sensor, the cooled housing, and the additional bandpass filter enables the ability for accurate level control despite the difficult challenges this application presents.
