ADB Bearing Sensor Tester
Adjustable Depth Bearing Temperature Sensor Tester
ADBTC1, ADBT4

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.

During planned maintenance or periodic testing, the ADB 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. Remove the ADB bearing sensor probe from the housing and insert it into the heater block. As the heater block reaches the alarm temperature, the ADB sensor will relay this data to the control unit, allowing you to verify that the alarm and shutdown sequences run as expected.

ADB Series Bearing Sensors

ADB Series Bearing Sensors

The ADB series have been designed to allow the depth of the sensor to be adjustable depending on your application. A number of versions are available with probe lengths of 50, 100, 200 and 300 mm. The sensors screw directly into a bearing housing through a 1/4” BSPT threaded grease zerk. Each sensor is fitted with a grease zerk to allow lubrication of the bearing without the need for removal of the sensor. The ADB series have NTC or PT100 type thermistors which allow for continuous temperature monitoring.

The sensor is supplied with a 3m attached cable and can be connected to a PLC or to a hazard monitoring system, such as 4B’s Watchdog Super Elite, T500 Hotbus Elite or T400 NTC Elite. The connections are not polarity sensitive therefore special connection requirements are eliminated, and the cable can be extended in the field.

PRODUCT DETAILS

  Can I use the ADB tester with other bearing sensors?  
  No, the ADB bearing sensor tester has been designed for 4B ADB sensors only.   

  Why is the LED display not functioning?  
  You may need to replace the two 9 volt batteries.  
     
  What does the battery low light indicator mean?  
  You need to replace the four AA batteries.  
     
  Why is the heater block is not warming?  
  You may need to replace the four AA batteries, the battery low light indicator should be on.  
     
  My ADB sensor is not responding as expected to testing, what could be the issue?  
  1. Make sure the ADB sensor probe is securely inserted all the way into the tester's heater block.  
  2. Check the alarm and shutdown settings on the control unit.  
  3. Replace the ADB sensor and re-test.  If the sensor is still not responding as expected, contact 4B.
