Pressure sensor is one of the most commonly used sensors in industrial practice, pressure sensor is generally made of pressure effect, also known as piezoelectric sensor. In the automatic control system of hydraulic press, the decision is whether to choose position control or speed control or pressure control, mainly the choice of sensors. Select the pressure sensor is the pressure control, select the speed sensor is the speed control.
The pressure sensor is added to the hydraulic press, the principle of which is through the data acquisition and system processing composed of microcomputer, so as to convert the pressure loading force value, display the number, and then send the sound and light alarm and stop signal, which is conducive to the automatic control of the pressure loading force, its advantages have the load display controller, the display is clear, the control is accurate, the response is fast, the work is stable and reliable, The replacement of different sensors and application software for forging equipment of different tonnage, the application of counters is conducive to the operator to count the total number and the number of unqualified, in addition, it also adds a two-handed button, which is conducive to improving the safety of machine operation.
