Mechanical Calibrating Machines – Model PCM
- Versatile, easy-to-use machine for compression and tension calibration of force instruments. Essentially two machines in this category, the PCM and the BCM. The Portable Calibration Machine (PCM) which has a maximum capacity of 2,000 lbf (10kN) , and the Benchtop Calibration Machine (BCM) which has a capacity of 10,000 lbf (50kN)
- Accuracy: The machine matches the accuracy of the reference standard. Most machines are aligned well enough that the maximum amount of side load is less than 0.0625 inches. On a shear web load cell this amounts to a possible error source of 0.003 %.
- CMC: Calibration and Measurement Capability is typically 0.02 % – 0.03 % or better.
Key Features
- Capacity: Handles loads up to 2,000 lbf (8.9 kN).
- Dual Calibration: Performs both tension and compression calibrations in a single setup.
- Portability: Weighs about 32 lbs and fits inside a compact carrying case with accessories.
- Fine Control: Uses a mechanical jack and fine-adjustment mechanism to reach and maintain precise target forces as low as 0.005 lbf.
- Efficiency: Eliminates the need to carry and stack heavy deadweights during calibrations.
- Tensiometer Support: Accommodates standard cable lengths up to 5 feet (models like the PCM-2MD-T1).
