Product Application - Screw Conveyor
         
 

4B has a wide range of sensors for monitoring the various parts of your screw conveyor. The most

 
 

common areas for monitoring include: bearing temperature, speed / motion, level / plug indication and

  
 

door / gate position.

 
     
 

All of 4B's sensors can be connected to our hazard monitoring systems.

Bearing Temperature Sensor
  

(1) Bearing Temperature Sensor

The sensor screw directly into a bearing housing through the existing grease zerk thread. Each sensor is fitted with a grease zerk to allow lubrication of the bearing without the need for
removal of the sensor.
