Torque Calibration

Torque Sensor, Tensiometer, Torque Wrench Calibration and More

Companies that work with torque instruments find that maintaining traceability and reliable measurement with routine torque calibration supports the quality of their operations.

LTI Metrology issues a Calibration Certificate for each item calibrated with all details of the torque calibration performed, including,

  • The lab’s information on NIST traceability and our A2LA accreditation to ISO/IEC 17025
  • “As Received” and “As Left” data showing adjustments during calibration
  • Comprehensive calibration results

Torque calibration can be performed at LTI Metrology with loads up to 2,000 Ft. Lbs. Our capabilities includes calibration and verification of many instruments within the ranges listed below:

The Torque Calibration Processes

“As Received” data is logged for all instruments based on predetermined test points. Torque calibration requirements are generated from a number of resources including manufactures, ANSI/ASME, Federal Specifications as well as customer requirements.

Torque wrench calibration, screwdriver (preset) and torque sensor calibration makes use of a torque system with the option to select the appropriate transducer for the range of the instrument from among multiple choices. Torque multipliers are also calibrated with transducers, but require the use of two. One transducer measures the generated torque input while the other measures the torque output.

Cable tensiometer calibration is carried out using a known cable diameter along with a fixed amount of deadweight attached to the cable. The cable tensiometer is affixed to the cable with the suspended weight to verify that the instrument is reading correctly. This test is repeated with an assortment of cables and loads appropriate for the instrument being calibrated.

Torque testers, torque watches and transducers are calibrated with torque wheels, arms and weights. This process is based on a calculation between a known length and weight to determine the torque generated.

Any adjustments made during calibration are recorded as “As Left” data.  Both are reported on the Calibration Certificate, along with the calibration results.
