Milli-Temp Series Bearing Temperature Sensor

New Product

Adjustable Depth Bearing & Surface Temperature Sensor


The Milli-Temp series can be used on any application where bearing temperature monitoring is needed.  The Milli-Temp is a loop powered analog sensor with a 4-20 mA linear output that is scaled across a temperature range for continuous temperature monitoring.  

The sensor has been designed to allow the depth of the probe to be adjustable depending on the application. This adjustability allows the tip of the probe to be placed in the optimal position for monitoring bearing temperature.

The sensor screws directly into the bearing housing using the threads of the existing grease zerk. The body of the Milli-Temp has an integrated zerk, allowing lubrication of the bearing without the need to remove the sensor.  For surface mount applications, a lug style adapter bolts directly onto a bearing housing, motor, gearbox, or machine casing. The mounting hole is 3/8” (10 mm approx.) from the factory, but can be drilled up to 1/2” (13 mm approx.) if needed.

The sensors are supplied with a nine foot cable. The connections are not polarity sensitive therefore special connection requirements are eliminated, and the cable can be extended in the field.

ADB Bearing Sensor Tester

The ADB Sensor Tester has been designed to test 4B adjustable depth bearing (ADB) style temperature sensors in the field. 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.

Combined belt speed (slip), belt alignment, continuous bearing temperature, pulley alignment and plug condition monitor for bucket elevators and conveyors.
IE Node

The Industrial Ethernet Node (IE-NODE) is a remote monitoring interface designed to provide sensor data to PLC’s or other automation and control systems.

Both units can be expanded to 16 sensor inputs with the installation of optional expansion boards.

How can I test the Milli-Temp bearing temperature sensor to make sure it is working correctly? 

 The ADB Sensor Tester (sold separately) is available to test all Milli-Temp sensors in the field.  See the   "Accessories" tab for more information.
