Model 3703 Calibration Transfer Standard

Description:

A transfer standard designed specifically for calibrating the torque transducers and control console used in the Model 3695 Torque/Force Calibrator. The Model 3703 Calibration Test Stand is furnished with all equipment necessary for calibrating the Model 3695 Torque/Force Calibrator, including loading arms, 500 lb. and 5,000 lb. proving rings, and a force gauge.

Features:
  • Calibration is accomplished through the use of a set of precision reference standards (proving rings and a quarts force gauge) and force moment arms, which can be installed on the output drive of the transducer.
  • Temperature correction algorithms for the reference standards and the length of the force arms have been incorporated into the Model 3695 control console software.
  • No calculations or corrections are required during the calibration process.
  • Generation and control of the torque applied to the transducer being calibrated is accomplished by a combination of a stepper motor, reduction belts, a ball screw actuator and force arm that is directly coupled to the transducer’s input drive.
  • The operator via a hand held variable potentiometer controls the direction and speed of the drive mechanism.
  • Calibrates Model 3695’s- 50, 500, and 5,000 ft-lb transducers.
  • When calibrating the 20,000 ft-lb transducer, hand crank and loader assemblies are used to manually apply the input torque.
  • The transfer standard consists of a rigid steel structural frame, force generator and a test bench, permitting the fixtures required for mounting the proving rings and force gauge.
  • The test bench also contains provisions for mounting the Model 3695’s control console during the calibration process.
  • A power supply module provides the power necessary to operate the drive mechanism and the Model 3695’s control console during the calibration process.

    Operating Temperature: +10°C to 40°C
    Non-Operating Temperature: -40°C to 75°C
    Humidity (operating): 85% RH (maximum), 10°C to 40°C

    500 lb. Proving Ring: Range 50 to 500 lbs., Accuracy ±0.125% lb. (maximum)
    5,000 lb. Proving Ring: 500 to 5,000 lbs., Accuracy ±0.625 lb. (maximum)
  • Dimensions & Weight:
    55.5”L x 25”D x 36”H
    794 lbs.
