FlatPack 21™ Sensors

Maxi-Tronic leads the industry in providing a wide variety
of reliable state-of-the-art and low cost temperature
sensors for your hazard monitoring needs.

FlatPack 21™ Surface Mount Sensors monitor the
surface temperature of equipment that cannot be
monitored with other sensors. Ideal for bearings, gear
boxes, motors, mills, or any mechanical equipment.

Use these sensors with Maxi-Tronic temperature
controllers, PC and PLC based systems. Combine with the Maxi-Tronic MaxiScan 12M Underspeed Detection and Temperature Controller for complete hazard monitoring and protection.
