How are a force transducer, dynamometer or load shackle calibrated, what do the ISO 376 classes mean and how are mass, weight and force related? Knowledge from our force laboratory. For a calibration in tension or compression, go to force calibration.
No law prescribes a fixed interval for force measuring instruments. Read how to determine a calibration interval on the basis of standards, use and history, and when you must recalibrate immediately.
Read article →The certificate of a force transducer states hysteresis, repeatability, reproducibility and zero return. Read what these terms mean, how they are measured and what you do with them.
Read article →ISO 376 divides reference force transducers into classes 00, 0.5, 1 and 2 on the basis of reproducibility, repeatability, interpolation error, zero error and hysteresis. Read what the classes mean and which one you need.
Read article →A load cell gives a signal in mV/V; only the readout turns it into a force. Read when to have the transducer calibrated on its own and when the complete measuring chain is the better choice.
Read article →A weight has a mass in kilograms, a scale measures a force in newtons and converts it back to mass. Read how mass, gravity, force and load cells are related and what that means for calibration.
Read article →A force calibration compares your force measuring instrument with a calibrated reference force transducer in the same line of force. Read how the measurement is performed, what tension and compression mean, which standards apply and what the certificate states.
