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)).

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.

Slide Gate & Shaft Position
-
All six Shaft Angle Position Feedback Monitors in the SG1000 Series utilize absolute rotary encoders to provide independent and accurate feedback of a slide gate's or a valve's position to an external device such as a PLC or optional PM500 Process Meter Display Unit. Models are housed in a rugged, Explosion-Proof/Dust-Ignition Proof cast aluminum enclosure that is dirt, dust, grease-proof, and water resistant. In the case of a power failure, all SG1000s are designed to retain accurate gate position.

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 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.

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.
