Why Do Force Calibration Adapters Matter? The Measurable Cost of the Wrong Setup A load cell that reads to 0.005 % of full scale in the laboratory can degrade to 0.5 % of full scale, or worse, in the field, mounted with adapters that introduce bending, side loading, or torsion. Same cell. Same certificate on […]
How to Calibrate a Proving Ring: No Bridge to Hide Behind A digital proving ring: the displacement sensor replaces the micrometer and vibrating reed, and the indicator displays the deflection. A proving ring has no strain gauge bridge to do the thinking for you, even when a digital indicator does the reading. It is a […]
How to Calibrate a Cable Tensiometer: The Cable is Part of the Measurement A cable tensiometer never touches a load cell or a hook. It clamps onto a cable and reads the tension in it. That one difference makes it among the trickier instruments to calibrate honestly, because the cable itself becomes part of the […]
How to Calibrate a Hand Held Force Gauge: Mount it Square, Not by Hand A hand held force gauge is the most-used force instrument in most plants and the least likely to be held the way it should be. It gets pushed across a bench by hand, and the certificate inherits every wobble. Good hand […]
How to Calibrate a Crane Scale: Reproduce the Way it Hangs A crane scale spends its working life hanging from a hook with a load swinging underneath it. Calibrate it any other way and the certificate describes a scale that does not exist. That is the whole problem with crane scale calibration. The instrument is […]
How to Calibrate Aircraft and Truck Scales: The Tire is Part of the Measurement in Aircraft and Truck Scale Calibration Three different size adapters made by Morehouse on a 10 000 lbf PT300 scale. Will there be a difference in the measured values? We loaded the same truck scale to 20 000 lbf (89.0 kN) […]
