Speed Switches and Controls

Tac-Switches provide accurate and reliable speed detection for conveyors, crushers and rotating shafts. With a digital display and easy-to-use programming buttons, you can eliminate calibration guesswork and achieve accuracy better than +/- 0.5%. Our Tac-Switches also offer a wide range of speed coverage, from 6 to 3000 RPM, and feature an OLED screen for quick monitoring of belt speed and RPM trip settings. Plus, with a DP/DT relay for direct contact or PLC input, built-in ramp timer and included DIN-rail mounting options, our Tac-Switches are the perfect solution for all your speed detection needs.

The BWI Eagle speed switches are housed in NEMA-rated enclosures that meet the environmental challenges of standalone installations. Select models speed switches feature a first-out indicator to simplify troubleshooting, decrease downtime and get machinery back on the line faster. These switches are ideal for applications requiring multiple channels to monitor both slip and sequence.

Intrinsic safety is a protection technique for the safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. Many industrial, chemical and process environments have significant explosion risks due to the presence of methane-air mixtures. Whenever equipment is installed where combustible material is present, it is essential to take steps to minimize the risk of ignition. Intrinsically Safe speed switches and sensors minimize power and heat creation, helping to ensure a safer work environment.

A Tac-Monitor is the perfect solution for converting rotary shaft speed into an analog 4-20mA output. With a digital display and easy-to-use programming buttons, you can eliminate calibration guesswork and achieve accuracy better than +/- 1%. Our Tac-Monitor also offers a wide range of speed coverage, from 10 to 6000 RPM, and features an OLED screen for quick monitoring of belt speed and RPM speed range settings. Plus, with the proportional speed and true slip monitoring of variable speed drives, continuous monitoring for zero-speed, under-speed and over-speed applications, a 4-20mA output for direct PLC input and included DIN-rail, our Tac-Monitor is the ultimate solution for your speed conversion needs.

The Overspeed Monitor and Decoder monitor speed and detect motion in conveyors, crushers, fans, motors and other rotating apparatus. It can monitor speed ranges of 30 – 3000 RPMs and includes a user-programmable 5 to 30-second fault timer. The Overspeed Monitor utilizes a non-contacting proximity sensor that may be remotely located up to two miles from the control unit. The control unit conveniently mounts inside an existing electrical panel or OEM control box with an included DIN-rail. The upfront display conveniently shows the current RPM in real-time.

BWI Eagle’s non-contacting sensors are designed for reliability in any industrial environment. They are available in Variable Reluctance (VR) and Inductive Proximity (Prox) types in three mounting styles. Completely epoxy sealed with LED indicators and integral MSHA signal cable, BWI Eagle’s sensors are virtually indestructible.
