Maxi-Tronic leads the industry in providing a wide
variety of reliable, low cost temperature sensors for all
your hazard monitoring needs.
HB21TM sensors are ideal for bearings, gear boxes,
bucket elevators, mills, grinders, conveyors, mechanical
drives and most other material handling equipment.
Use these “Hot Bearing” sensors with Maxi-Tronic
Temperature Controllers and all PLC/PC based systems.
Combine with the Maxi-Tronic MaxiScan 12M Underspeed
Detection and Temperature Controller for
complete hazard monitoring protection.
HB21™ Sensors in Action
- Easy-to-adjust length for any size bearing.
- HB21 Series Bearing Sensors allow greasing the bearing without removing the sensor.
- Easy to install and maintenance free. Just screw the stainless “Housing” into an existing 1/8”, 1/4” or 8mm Zerk tting hole then slide in an “Insert” .
- Sensing element is located at the bearing race for the most rapid and accurate readings. Brass-tipped for improved thermal conductivity and accuracy.
