4B Components Ltd. Introduces ADB Bearing Temperature Sensor Testing Device

Date Posted: March 19, 2013

Morton, IL—4B Components Ltd., a worldwide manufacturer of material handling and electronic components for bucket elevators and conveyors, has developed a new maintenance tool that makes the testing of 4B adjustable bearing temperature sensors quick, easy and accurate.

This hand held test unit features an integrated heating block specifically designed to have a 4B ADB sensor directly inserted.

With integral controls and temperature display, the unit heats the sensor to the desired trip point, and allows quick and easy real life testing of the sensor and temperature monitoring system.

During planned maintenance or periodic testing, the ADB bearing sensor tester can be used as a diagnostic tool to verify the alarm and shutdown sequences of the control unit are functioning as expected.

To test, the heater block should be set above the control units alarm operating temperature.

As the heater block reaches the alarm temperature, the ADB sensor will relay data to the hazard monitoring control unit, verifying that the alarm and shutdown sequences run as expected.

This type of testing is critical in dust hazardous environments where bearing failures can become a possible ignition source for explosions.


Founded in the 1971 as a subsidiary of The Braime Group, 4B has been an industry leader in developing high quality, innovative, and dependable material handling components for the agricultural and industrial sectors.

4B’s product line ranges from elevator buckets, elevator bolts and drop forged conveyor chain to level monitors, speed switches and hazard monitoring systems.

With offices in North America, Europe, Asia, Africa and Australia along with a worldwide network of distributors, 4B can provide practical solutions for applications in any location.
