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) […]
How to Calibrate Tension Links and Load Shackles: It is all About the Pin When it Comes to Tension Link Calibration A tension link is calibrated on its pins, not on its label. Two links stamped with nominally the same capacity can behave completely differently under load because they were built around different pins, and […]
How to Calibrate Button Load Cells in Compression: A Guide for Button Load Cell Calibration A button load cell looks like the easiest thing in the world to calibrate. It is small, it takes load through a domed top, and you set it under a press and push. What could go wrong 😊? Almost everything, […]
How to Calibrate an Analog Dynamometer: Set it up the Way it is Used Pictured above is a 10 000 lbf Analog Dynamometer in a Morehouse 10 000 lbf BCM. An analog dynamometer has no electronics to trust and no digital display to read for you. It has a spring element, a mechanical linkage, and […]
