Abstract
A method and a device for detecting the switching value of a pressure switch. The device comprises: a pressure generator in communication with a pressure switch by means of pressure piping, a pressure control element, a pressure sensor, and a controller provided with a data processing unit. The pressure sensor is installed on the pressure piping and is electrically connected to the controller. The pressure control element is electrically connected to the pressure generator to control the pressure generator, and is electrically connected to the controller. The pressure sensor transfers the pressure change of the pressure piping to the controller in real time, the data processing unit acquires the value of the pressure change and generates a control instruction according to a preset pressure change rule, and the pressure control element controls the pressure generator to change the pressure within the piping. The device and the method are used to complete the detection of the switching value of a pressure switch, fast detection is achieved, the detection accuracy is improved, the repeatability of the detection result is good, the manual operation cost is reduced and the operation is …
