Wired Hazard Monitoring
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 (1910.272(q)(4)(ii), 1910.272(q)(5), 1910.272(q)(5)).

Belt Alignment Sensors And Misalignment Switches
Electro-sensors belt alignment sensors are mounted along the conveyor belt that needs to be monitored for misalignment. The rub block assemblies are mounted so that the brass surface area is in-line with the edge of the conveyor belt. When the belt wanders it then rubs up against the brass block. The contact with the belt creates friction and heat that the sensor in the brass block records as a rise in temperature.

Shaft Speed Switches
A speed switch senses rotating shaft speed, comparing it to one or more settable over/under/zero speed alarm trip-points. A shaft speed sensor detects magnets embedded in a shaft-mounted pulser wrap/disc. As the shaft rotates, the passing magnets are detected across an air-gap as pulses with frequency proportional to shaft RPM. When a conveyor belt or bucket elevator begins to slip the pulse frequency (shaft RPM) crosses to the alarm side of a trip-point threshold, a corresponding relay de-energizes, providing shutdown or alarm.

Shaft Speed Pulse Generators and Shaft Speed Targets
Shaft Speed Targets are needed to generate a pulse for a Speed Sensor that is monitoring a shaft for RPM (Revolution Per Minute). Electro-Sensors Pulse Generators provide the shaft speed target needed for shaft speed detection with a sensor or switch. We have many options available for all your application needs including customizable split collar pulser wraps.

Shaft Speed Sensors
Electro-Sensors offers many shaft speed sensors for virtually any environment. Our Hall-Effect and Magnetoresistive Sensors sense magnetic targets and work with our magnetic pulsers (Discs, Wraps, and Wheels). Our proximity sensors sense ferrous metal targets, including bolt-heads, screws, gearteeth and keyslots. Our speed sensors monitor shaft speed of equipment and output data as PNP, NPN, or 4-20 mA signals. The sensor data can be used by facilities to monitor machinery and safeguard equipment. Monitoring shaft speed is a fundamental aspect of hazard monitoring and should be utilized by any facility with rotating shafts.

Wireless Hazard Monitoring
When it comes to hazard monitoring, we know it simply has to work. HazardPRO was designed from the ground up to provide turnkey, reliable, and consistent protection for your most valuable assets—products, facilities, and most importantly, people. Consistent operation is ensured with built-in tools such as self-diagnostics, transmission logging, and redundant radios providing you confidence that your critical processes are being monitored and logged at all times. Wireless nodes utilize temperature (bearing, ambient, and stud), RPM shaft speed, alignment, and vibration sensors. Ambient Sensors ensure bearing and alignment measurements are relative to the surrounding environment.
