Universal Calibrating Machine (UCM)

Morehouse Universal Calibrating Machines (UCM) are an easy to use, cost-effective, hydraulic force calibration system that lasts for generations. UCMs built in the 1950s are still operating today! The UCM can be used to calibrate both tension and compression instruments in accordance with ASTM E74, ISO 376, and other internationally recognized force standards.

The operator can replicate how the force instruments are used in the field by using different setups for tension and compression, and proper adapters recommended by several standards, including ISO 376.

The Universal Calibrating Machine is a superior alternative to expensive automated solutions, which often do not work due to the nature of the instruments being calibrated. An automated machine will not allow the technician to calibrate analog devices or devices without some sort of data communication. These machines often cost 50 % less than the fully automated solutions offered from other manufacturers.

The Morehouse Universal Calibrating Machine operates efficiently with very low operational and maintenance cost. Accessories such as quick change tension members, tension member adapters, alignment bushings, and studs are available to help adapt load cells of many varieties for calibration. Optional hydraulic power control with an auxiliary screw pump is recommended for capacities over 60,000 lbf.

Features include:

  • Facilitates both compression and tension calibration
  • Reference standard will only need calibration in compression mode. This reduces the lifetime ownership cost when compared with machines that require the reference standard to be calibrated in tension and compression.
  • Accommodates different size load cells and crane scales
  • When used with standards calibrated to ASTM E74 with a Class AA range, ASTM E74 Class A loading ranges can be assigned
  • When used with standards calibrated to ISO 376 Class 00, the machine is capable of calibrating instruments to Class 0.5
  • Design assures axial loading
  • No error from friction loss
  • Matches the accuracy of the reference standard
  • Expanded uncertainties of better than 0.02 % of the applied force, when used with several Morehouse Ultra-Precision Load Cells calibrated using deadweight primary standards
  • Easy to use; training takes less than one hour
  • Capacities from 100 lbf through 3,000,000 lbf (13.3 MN).

If you are looking for an accurate, easy to use, cost-effective machine, the Universal Calibration Machine will exceed your needs. It can be used to calibrate the following force-proving instruments:
