NKY-YW/TW/Z W Wireless Torque Control System

(Y: tubing power tongs; T: casing power tongs; Z: drill pipe power tongs)

NKY-YW/TW/ZW wireless torque control system is usually used together with tubing power tongs, casing power tongs and drill pipe power tongs. It is a multi-purpose recorder capable of setting, measuring and displaying the make-up torque to ensure an optimal make-up torque. This torque control system adopts wireless data communication. Wire communication is also available when the wireless communication is interfered or the battery runs out.

This torque control system includes a torque display, computer, torque signal sensor, damp valve, wireless transmitter, wireless receiver, etc.


  • The adoption of wireless communication requires no lay out of cables on site.
  • The data transmitter is powered by battery. When the battery voltage is insufficient, it can also be wired to achieve both wired and wireless use.
  • Good versality: it is compatible to tubing power tongs, casing power tongs and drill pipe power tongs.
  • This torque control system is suitable for make-up operations of special threaded connection such as VAM TOP, BGT1, FOX, 3SB, 13Cr, etc. It supports the measuring and recording of make-up torque, shouldering torque, rounds and the ratio of make-up torque to shouldering torque.
  • Based on the operation requirements, the make-up parameters, including pipe and coupling parameters, ma/min torque, etc.
  • High precision, high rotation speed optical-electricity encoder is adopted to record the screwing rounds.
  • 12 bits high precision analog A/D conversion module ensures high sampling rate.
  • Torque sensor is equipped corroding to the model of the hydraulic power tongs.
  • Displaying, controlling and recording of make-up parameters are available. The data can be recorded on a disk for future review.
  • Multiple printing choice: one or eight graphics can be printed on A4 paper.
  • Reliable hardware and software provide complete function, easy operation, reliable running and convenient maintenance.
