Triboelectric Monitor Detects Filter Leaks, Failures

Monitor's DustAlarm dust monitor or "broken bag" detector

The DustAlarm dust monitor or "broken bag" detector is designed to continuously monitor for filter failures and leaking filters in the exhaust ducts of bag houses, cartridge collectors, cyclones, and other dust collection systems containing filters that may break or wear out with time. The DustAlarm uses triboelectric technology to monitor the level of dust emission in dust collection system exhausts. Triboelectric measurement has been used for years to detect filter failures in bag houses. The triboelectric effect, also know as “particle impingement,” occurs when one material impacts or rubs another causing a charge transfer. When an increase in particle emission level exceeds the user adjusted setting, an alarm is triggered as indicated by the unit's output relay changing state. The time-delay feature can minimize false signals from brief instances of higher dust levels caused by cleaning cycles, etc. The DustAlarm has an extended insulator to guard against material build-up problems, as well as, a quick-disconnect mounting coupling to provide quick and easy installation and maintenance when needed.
