Torque Wrench Tester/Calibrator

A torque wrench calibrator is used as a quality control device to measure or calibrate torque controlled tools. This includes electronic torque wrenches, click torque wrenches, dial torque wrenches, electric screwdrivers, air screwdrivers, pulse tools, cordless screwdrivers, nut runners, and torque screwdrivers. PRC offers advanced torque calibrators that include the ability to measure torque in clockwise and counter-clockwise direction.

PRC offers its innovative range for Torque Wrench Calibrators suitable for the following types of torque wrenches; Electronic torque wrenches Click torque wrenches Dial torque wrenches Electric screwdrivers Air screwdrivers Pulse tools Cordless screwdrivers Nut runners Torque screwdrivers

Torque calibrator

Salient Features:

Easy to use, robust Workshop Torque Calibrators providing +/- 1% accuracy Data management facility via a RS 232 output that allows data to be exported to computer in Computerized version Versatile Torque calibrator offering Torque Tool checking with multiple models available covering a range from 0.2 to 5000 Nm Long service life ensured by a simple lightweight design

System consists of;

Torque Transducer – PRC offers strain gauge type torque transducers, similar to a load cell, which is an electronic device used to convert torque into an electrical signal. This conversion is indirect and happens in two stages. Through a mechanical arrangement, the torque being sensed deforms a strain gauge. Offered capacity for these transducers is from as low as 1 Nm to 10,000 Nm on higher side as standard transducers. Further to this customized solution is offered. Enough care has been taken while designing & construction of transducers to ensure the precision measurement, reliability & long term durability for nonstop performance. PRC offers stationary (reaction type) torque transducer used for different measurement & calibration.

Technical Specification:

  • Rated Capacity: from 1 Nm to 10,000 Nm
  • M.O.C.: Stainless steel
  • Safe overload: 120% of rated capacity
  • Ultimate overload: 200% of rated capacity
  • Accuracy: ± 0.2% of rated capacity
  • Excitation: 1 mV/V
  • Operating Temp.: 0 to 50 ??C
  • Protection: IP-50

Digital Torque Indicator – PRC offers a micro controller based digital display for its torque testers. This digital display is used to measure the output signal from the transducer and calculates that reading into a torque value that is displayed on screen. Special version of digital displays is available for external rotary and stationary transducers. These displays are with bright LED and keypad to set the parameters.

Technical Specification:

  • 6 Digit 7 segment LED display
  • Input: Strain Gauge based Sensor
  • Output: 2 Relay output for LOW & HIGH Limits
  • Calibration: Multi point (10) for non linear application
  • Special Facility: Provided for Unit conversion & Peak hold
  • Key Pad: 4 Keys for parameter setting

Fixture to hold the torque wrenches

PRC provides mechanical fixtures to hold the torque wrenches which may be required for need of calibration. There are some standard fixtures available for standard type of tools and customized fixtures also provided in case of non standard tools.
