Tachometers
HH100
The HH100 Hand-Held Digital Tachometer combines both contact and non-contact sensing to accurately measure RPM, surface speed, and length. When using the non-contact mode, rotational speed (RPM) is measured using a visible beam of light. The HH100 can be up to 14 inches away from the small piece of reflective tape that is affixed to the rotating element.

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)

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.

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.

Pulse Generators
Split Collar Pulser Wraps
Pulser wraps clamp around a rotating shaft and work with Electro-Sensors shaft speed sensors and are an ideal solution for installations where the end of the shaft is inaccessible. The two halves fasten together around the monitored shaft with recessed Allen head socket screws (provided). Standard and custom models accommodate any shaft diameter, tight spaces, and keyways. • Standard wraps operate to 3,000 rpm (high-speed also available) • Standard wraps available in PVC, aluminum, or stainless steel
