High-Precision Testing Weight Wireless Digital Dynamometer Load Cell

The standard force measuring instruments used for the verification or comparison of static weight, lever, hydraulic, and superimposed force measuring machines are mostly of the force measuring sensor type, and their accuracy is divided into three levels: 0.01, 0.03, and 0.05. After various forms of force measuring sensors are equipped with appropriate electrical measuring instruments, they constitute a sensor type force measuring instrument or an electronic force measuring instrument. Standard force-measuring instruments still rely mainly on resistance strain type sensors with wide range, high accuracy, and strong adaptability. Standard force-measuring instruments used for the verification or calibration of various material testing machines are mostly dial gauge type, with accuracy levels of 0.03, 0.05, and 0.1.

A portable measuring instrument used to measure various force values or loads. Also known as a dynamometer. There are various classifications, divided into working force-measuring instruments and standard force-measuring instruments according to the object of use. The main indicators for evaluating the accuracy level of a dynamometer are repeatability R and stability Sb. R reflects the changes in data obtained from multiple loading (unloading) during a complete verification process; Sb reflects the difference between the verified data and the last data after a period of time.
