Dust Detector uilizes Tribo elecetric technology, whereby the collision and interaction of particles with the prob rod causes a small electrical charge transfer to occur. This small electrical charge provides a signal that is monitored by the electronics in the device. It is designed to prevent false readings, even if an accumulation of dust forms on the sensor rod. It can be set to make pre warning indicator alerts to potentially hazardous situations or be set to provide an instantaneous alarm or one minute averafed readings. There is a 4-20 mA output for applications where Dust Detect will be used with a PLC. The Dust detector helps to prevent the loss of valuable product and dramatically improves the safety of the workplace by alerting personnel to change in emission levels before they become serious, which can virtually eliminate emission-related shutdowns. Dust Detectors continuosly monitoring emissions, bag house filter leaks and process particulate flow.
