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.

Magnet Wheels Pulse Generators
199SM / 198EM Magnet Wheels
-
Magnet wheels work with Electro-Sensors Hall Effect shaft speed sensors providing 120 alternating magnetic poles around the circumference of the 3.75" diameter. The 199SM models mount around shafts up to 3" in diameter and are secured with set screws (provided). The 198EM mounts on the end of a shaft with a 10-32 UNF screw (provided - requires center drilling and tapping the shaft).• Use with 906, 906B, 1101 and other Hall Effect, non-metallic-end-capped shaft speed sensors (consult factory)

Encoders
380 / 470 Rotary Shaft Encoders
-
The 380 Encoder is a standard industrial grade encoder available with single channel or bi-directional (quadrature) output. The 470 Heavy Duty Encoder provides a bi-directional (quadrature) output with an index pulse.• Square-wave frequency output• NPN open-collector and line driver (470) options• 5-28 VDC powered

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.

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.
