DN-130A is a modified load sensor with the auxiliary output 4-20 мА (for automated rig control system).

DN-130A is an attachable sensor used to measure cable load.

It’s used to measure “weight on hook” in the SKPB DEL – 150 system.

To measure weight on hook DN-130A is mounted on the fixed drill or workover rig cable end.

 
Measuring parameters:
 

Capabilities:

  • Same size sensors are interchangeable;
  • The sensor is Ex-rated;
  • Conventional analogue output 4-20 мА is supported.

Design features:

  • The advanced design sensor enables much higher weight on hook accuracy compared to conventional sensors;
  • Distributed load on the sensor mounted to the hoisting rig cable eliminates «setup error;
  • No threaded connections to mount the sensor;
  • Three size load sensors DN-130A are available.
