Problems solved by technology

[0002] For many years, for the calibration of high-range pressure sensors, most people use piston pressure gauges. Using this method requires manual handling of weights, manual readings, and manual calculations. This method is not only inefficient, but also labor-intensive and expensive. There are some automatic calibration equipment in the market, but the pressure medium uses gas, which can only solve the automatic calibration of pressure sensors in the range of 0-20MPa. Therefore, people have long needed a calibration device for high-range pressure sensors

Description

technical field [0001] The invention relates to a force standard device, in particular to a thrust device with a large amplification ratio. Background technique [0002] For many years, for the calibration of high-range pressure sensors, most people use piston pressure gauges. Using this method requires manual handling of weights, manual readings, and manual calculations. This method is not only inefficient, but also labor-intensive and expensive. There are some automatic calibration devices in the market, but the pressure medium is gas, which can only solve the automatic calibration of pressure sensors in the range of 0-20MPa. Therefore, people have long needed a calibration device for high-range pressure sensors. Contents of the invention [0003] In order to solve the above problems, the present invention provides a high-magnification ratio thrust device with high precision and large measurement range. [0004] In order to achieve the above object, the present inventio...
