2017-04/electronicforcemeasurementsystems

  • Metriguard’s finest force measurement system
  • Standard with Models 412 and 422 Tension Testers Optional with Models 401 and 403 Tension Proof Testers, and Models 810 and 870 Compression Testers
  • Eliminates errors caused by cylinder friction in hydraulic pressure indication of force
  • Provides direct digital readout of force as well as analog output of force signal
  • Measures in either standard English or metric units

The Metriguard electronic load cell force measurement system is standard for the Models 412 and 422 Tension Proof Testers. It is also available as an option for the Models 401 and 403 Tension Proof Testers and the Models 810 and 870.

A general purpose version of the system is available for special customer applications, in which case the load cell is extra because it needs to be specified to fit the application.

A shunt calibration feature is provided with each system. Once the system is calibrated, the calibration is easily checked with a push-button calibration switch on the electronic unit’s front panel. This method uses the system’s load cell as a calibrating device. If the calibration checks without adjustment when using the shunt calibrator, the operator can be confident that the force measurement system has retained its calibration.

  • An electronic load cell force measuring system consists of an electronics unit and a load cell.
  • The electronics unit applies stabilized signals to the load cell and processes the signals from the load cell with low noise amplification and coherent detection methods. These methods increase the dynamic range of forces that can be measured.
  • The load cell is physically located within a machine so that the load to be measured or a known fraction of it is applied to the load cell.
  • Load cells used by Metriguard are carefully selected to be stable and reliable with appropriate tolerances for variables such as temperature, off-axis loading, and overload. Other selection criteria include linearity and senstitivity.
