Hopper Ash Level Thermocouple System
HALT - Integrated Test + Measurement (ITM)
The Hopper Ash Level Thermocouple (HALT) System is a preventative maintenance and safety tool that continually monitors the levels of ash within a hopper. As the hopper plugs and the ash levels increase, the thermocouples will become insulated from the boiler heat by the ash. Low temperature readings trigger visual and digital alarms which indicate that the hopper has plugged.
