Dynamometer calibrating device

Technical Field

The utility model relates to a dynamometer calibrating installation.

Background

The measuring device of the work dynamometer works according to the principle of the static effect of force and is used for measuring the measuring instrument of the work dynamometer.

Currently, a force gauge (a force measuring instrument) is widely applied to measurement of tension and pressure. With the development of technology, many dynamometer with sensors are currently available on the market, and these dynamometer actually use sensors to measure the pull and pressure and display the measured values on a display screen on the dynamometer surface.

Since the type of the dynamometer is not limited, a verification device capable of detecting various types of dynamometers cannot be found, and a conventional dynamometer cannot be normally detected. Therefore, the traditional verification method is to fix the dynamometer on a frame, then directly load the dynamometer on the standard weight to measure the value of the force measurement, and the method limits the measurement point to the mass of various weights, and the measurement point is a plurality of discontinuous values, so that the verification is not accurate enough.

At present, manual measurement is mostly adopted in the verification process, the accuracy of an instrument cannot be kept in an optimal state, errors are easy to generate, and the accuracy of the instrument cannot be reflected in a real sense.
