4B sensors protect conveying equipment, such as bucket elevators and conveyors, from the risks of explosions and equipment failures.

This video showcases 3 of 4B’s products: the Whirligig universal shaft sensor mount, the Touchswitch belt and pulley alignment sensor, and the ADB adjustable depth bearing sensor.

4B Whirligig – Universal Target /Mount for Motion Sensors
4B’s Whirligig® is a fully guarded target for easy mounting of motion sensors, ideal for the use on bucket elevators and conveyors. It is a universal shaft sensor mount suitable for all industry standard cylindrical or DIN style inductive sensors including 4B’s M100, M300, and M800 speed switch sensors and P100, P300 and P800 inductive sensors.
The sensor bolts to the Whirligig base plate and the complete assembly either bolts to the machines shaft through a M12 tapped hole, or is connected magnetically using 4B’s patented Mag-Con™ adaptor. Shaft or machine vibration does not affect the performance of the sensor, as the whole assembly moves with the shaft. With the Whirligig, installation of speed sensors is simple, safe and reliable.

TouchSwitch – Belt /Pulley Misalignment Sensor for Bucket Elevators & Belt Conveyors
4B’s Touchswitch is an electro-mechanical misalignment switch bucket elevators and belt conveyors. When a belt misaligns or a pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley and activates a voltage-free solid state relay output. This output signal is used to immediately alarm and ultimately shutdown the machine.
The face of the sensor is made from hardened and annealed stainless steel, for optimal wear resistance. The Touchswitch is not affected by dust or material build up and will still work when completely covered by material. An external test wheel allows for quick and simple sensor/system testing. The sensors are usually installed in pairs on opposite sides of the machine. The Touchswitch sensors can be connected directly to a PLC, or to one of 4B’s hazard monitoring systems, such as Watchdog Super Elite, IE-Node or the T500 Hotbus system.

ADB Bearing Temperature Sensor
4B’s ADB NTC & Pt100 bearing temperature sensors for continuous bearing temperature measurement have been designed to allow the depth of the sensor to be adjustable depending on your application. Available with probe lengths of 50, 100, 200 and 300 mm, the ADB sensors. The sensors screw directly into a bearing housing through a 1/4” BSPT threaded grease zerk. Each sensor is fitted with a grease zerk to allow lubrication of the bearing without the need for removal of the sensor.
The sensors are supplied with a 3m attached cable and can be connected to a PLC or to a hazard monitoring system, such as 4B‘s Watchdog Super Elite, T500 Hotbus Elite or T400 NTC Elite. The connections are not polarity sensitive therefore special connection requirements are eliminated, and the cable can be extended in the field.
