Sensor Applications

1. Bearing Temperature Sensors

The WDB, MDB, and ADB Series bearing temperature sensors screw directly into an existing grease zerk fitting on a bearing housing. The sensors are equipped with a grease fitting for lubrication of the bearing without needing to remove the sensor. Most series are available with either a PTC thermistor with various factory-set trip points, an NTC thermistor with a user-adjustable trip point, or as a Pt100 RTD version.

2. Speed Switches

The speed switches monitor rotating machinery for dangerous under speed conditions. An inductive sensing device located in the nose of the enclosure will detect a metal target. Set to the standard machine RPM, 4B Speedswitches provide alarm and shutdown signals under speed and stopped motion.

*Can be used with the Whirligig universal shaft sensor mount 3 Binswitch.

3. Binswitch

The Binswitch detects level or plug conditions for bulk granular solids or liquids in tanks, bins, and silos. It can be used as a plug or choke detector in chutes, conveyors, and elevator legs.

4. Roto Level Series

The Roto Level Series are rotary paddle switches designed to detect high and low levels of bulk granular solids in bins, tanks, silos, and as blockage detectors in spouts.

5. WDA 3

The WDA Series are non-contacting extended range magnetic sensors used to detect ferrous targets (such as bucket bolts or steel buckets) at a distance of up to 75mm from the sensor. It can also be used as a chain break detector.

6. Touchswitch

The Touchswitch is an electro-mechanical limit-switch style sensor with no moving parts. It is designed to detect belt tracking and misalignment problems on bucket elevators and conveyors. Unlike a rub block that utilizes friction (heat) to activate, the Touchswitch is pressure sensitive for safer and more reliable monitoring.

7. Inductive Sensors

4B inductive proximity sensors are designed to detect shaft speed, shaft position, gate position, or object presence. No contact is made between the monitored sensor and the target. Sensors will detect a ferrous object at 12mm and a non-ferrous metal object at a distance of 8mm.
*Can be used with the Whirligig universal shaft sensor mount.

8. Autoset Series

The Autoset Series are self-contained point level monitors with digital displays for high, intermediate, or low-level detection of liquids, powders, or free-flowing granular solids. The Autoset Series incorporates simple push-button calibration with microprocessor enable/disable switch for total protection of stored values. Once the unit is calibrated for a specific application, it never has to be re-calibrated.

Monitoring Your Equipment

Bucket Elevators

The most common hazards on bucket elevators are belt misalignment, belt slippage, blocked chutes, and bearing failures.

Belt Conveyors

Monitor belt conveyors for dangerous conditions and prevent costly downtime.

Chain Conveyors

Monitor bearing temperature, speed/motion, level/plug indication, and slack/broken chain detection.

Screw Conveyors

Blockage detectors, bearing temperature monitors, and rotation speed monitor.

Silos & Storage

Level indicators for point level indication of bulk granular solids, or powders in bins and silos.

Monitoring

Preventative maintenance reduces the risk of equipment failure and consequent downtime. Not all scenarios require hazard monitoring, but all types of plants and equipment can benefit from it.

Sensors & Systems

Bearing Temperature

Overheated bearings are one of the main risk factors for dust explosions in bucket elevators, and need to be closely monitored. We offer a range of Atex, CSA, IECEx and GOST-R certified bearing temperature sensors and compatible monitoring systems.

Speed Switches

Our line of speed switches includes proximity, inductive, zero speed, stop motion, and rotech encoders to monitor dangerous belt slips, under-speed or stop-conditions on conveyors, bucket elevators, and any other shaft driven machinery. Our non-contacting sensors can detect screw conveyor flights, elevator bucket bolts, and other moving ferrous targets. Speed switches can be connected to a PLC or to one of 4B’s hazard monitoring systems to provide alarm and shutdown of your machinery when dangerous conditions are detected.

Inductive Sensors

Our inductive proximity sensors are designed to detect shaft speed, shaft position, gate position or object presence. No contact is made between the sensor and the monitored target.

Alignment

Sensors and switches designed to detect (mis)alignment and motion on bucket elevators and belt conveyors. The WDA sensor can also be used as a slack chain detector on drag chain conveyors.

Level Indicators

Level indicators to detect high/low levels of bulk granular material in bins, tanks, and silos. The range includes capacitance point level indicators, rotary paddle switches, and capacitance proxy  level/plug detectors. 4B level sensors can be connected to a PLC or to one of 4B’s hazard monitoring systems to provide alarm and shutdown of your machinery.

Junction Boxes

Junction boxes allow for easy installation of sensors in potentially explosive dust hazard environments.

Hazard Monitors

Hazard monitoring systems are designed for bucket elevators and conveyors in dust hazard environments.

Bucket Elevators

The bucket elevator is one of the most efficient methods for elevating bulk granular materials – but also one of the most dangerous.

The dust generated from the movement of materials within the elevator can be highly explosive, and mechanical failure or incorrect operation of the bucket elevator can have catastrophic consequences.

The most common hazards on bucket elevators are belt misalignment, belt slippage, blocked chutes, and bearing failures, each of which requires monitoring to reduce the risk of fires, explosions, or breakdowns that result in costly downtime.

We have a wide range of sensors for monitoring the various parts of your bucket elevator. The most common areas for monitoring include: bearing temperature, speed/motion, belt alignment, and level/plug indication.
All of our sensors can be connected to our hazard monitoring systems.

Belt Conveyor

Belt Conveyors are used in a range of bulk materials handling applications, including grain handling, quarrying, and mining. They consist of two or more pulleys with a continuous loop of conveyor belt that rotates around them.

Conveyor Components supplies a complete range of ATEX/IECEx/CSA approved monitoring equipment for belt conveyors, designed to monitor for dangerous conditions and prevent costly downtimes.

The range includes belt misalignment and belt rip detectors, speed switches, bearing temperature sensors, choke switches, pullwire conveyor safety stop switches, and multi-functional monitoring systems for belt conveyors.

The most common areas for monitoring, include: bearing temperature, speed/motion, belt alignment, and level/plug indication.
Sensors can be connected to our hazard monitoring systems.

Chain Conveyor

Chain Conveyors are essential for conveying bulk materials such as powders, grains, flakes, and pellets.

The most common areas for monitoring include: bearing temperature, speed/motion, level/plug indication and slack/broken chain detection.

Sensors can be connected to our hazard monitoring systems.
