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.

We offer both wireless and wired hazard monitoring system options. Our  turn-key HazardPRO wireless hazard monitoring system is the first of its kind combining rugged sensors, intuitive software, and the most advanced wireless technology to create the best hazard monitoring solution with the lowest installed cost.
