4B develops bearing temperature sensor
Published by Lucy Stewardson,
4B Components Ltd has developed a new loop-powered analogue sensor with a 4-20 mA linear output that is scaled across a temperature range for continuous temperature monitoring. The Milli-Temp series can be used on various applications, where bearing temperature monitoring is needed.
The sensor has been designed to allow the depth of the probe to be adjustable depending on the application. The adjustability allows the tip of the probe to be placed in the optimal position for monitoring bearing temperature and also enables verification using the 4B ADB Tester.
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.
The sensors are supplied with a 9 ft cable. The connections are not polarity sensitive, meaning special connection requirements are eliminated and the cable can be extended in the field.
“This new and elegant design provides a 4-20 mA output directly from the sensor, eliminating the need for an external transmitter,” said Brian Knapp, Vice President of Electronics at 4B.
