Hazard Monitor Overview

Grain dust is extremely volatile and can easily explode with the proper ignition source in confined spaces. OSHA has mandated that grain elevators in Class II, Division 1 environments must have the 3 monitoring sub-systems for elevator safety. (Note: this same rule applies to the flour and sugar processing industries). Electro-Sensors Hazard Monitoring Systems are used to minimize the risk of such explosions by early detection of conveyor/elevator slowdown, hot bearing temperature, or belt misalignment – all of which can present an ignition source. Complete Hazard Monitoring Systems are capable of monitoring one leg up to 31 legs.


Electro-Sentry 1

Single-leg or conveyor Hazard Monitoring System for monitoring shaft speed, bearing temperature, and belt alignment. All sensors have their value and alarm status displayed in LED's on the front panel. Includes a programmable hour meter for scheduling maintenance based on run-time. Electro-Sentry 1 uses Electro-Sensors speed and temperature sensors.
