Function

The DKM-140 torque sensor is designed to measure the torque and speed of rotary drilling tables. The sensor measures the torque and speed of the rotary table and, using the data entered by calibration and stored in its nonvolatile memory, calculates the real value of the measured torque. The final result of measurments is transformed into a digital signal and transmitted through a communication line for displaying of the measured data or its further application in automated process control systems.

Advantages

  • Small size;
  • The sensor can be made to a particular customer's order;
  • It can process two parameters simultaneously (torque and rotor speed).

Additional information

The DKM-140(Ts) version is developed for chain-drive installations.
