Intelligent Digital Pressure Switch for Air Compressor Industry

Product Description

Product introduction:
With delay control, reverse control, pressure unit switching, error clearing, password protection and other functions.

It has the characteristics of good shock resistance, long life, impact pressure resistance, etc. It is especially suitable for hydraulic presses, high-pressure air compressors, high-pressure cleaners and various automatic control machinery.

There are three basic types of air compressors: swing type, rotary type and centrifugal type. It can usually be subdivided on this basis. The pressure in general industrial air compressors is as small as 2hp to 10,000hp. Air compressors are mainly used in pneumatic control, execution, injection equipment, pneumatic tools, air discharge operations and other applications. The most common air compressor generally has a working pressure of 125pis (about 8.6 atmospheres) and a gas flow rate of 1CFM to 15000CFM.

Generally, the control principle of air compressor is to use the pressure of compressed air (cylinder) to act on the pressure switch. If the pressure is greater than the set pressure value of the pressure switch, the switch will cut off the control power of the contactor and stop. If the pressure is lower than the set pressure value of the pressure switch Around 60%, the switch turns on the control power supply of the contactor and operates. So as to ensure that the pressure is maintained within a preset range, and achieve the effect of the use of rear-end air outlet. Generally, mechanical pressure switches are used, which have poor control accuracy and narrow adjustable upper and lower limits, which are not suitable for precise control.

Shanghai Meokon MD-S series digital display pressure controller adopts the latest application-specific integrated circuit and high-precision pressure sensor design. This product is more convenient in pressure setting, wider adjustable range, higher precision, and higher accuracy and stability.

MD-S series digital display pressure controller is a multifunctional intelligent switch integrating pressure measurement, display and control. When the pressure reaches a predetermined value, the control signal is output, and the controlled equipment is turned on or off to realize the purpose of automatic control. This series of controllers has the advantages of high accuracy, low hysteresis, fast response, stable and reliable performance, easy operation and simple and flexible installation. It is a high-tech product for automatic pressure control using microcomputer technology. It has the characteristics of high precision, low hysteresis, fast response, stable and reliable performance, easy operation and simple installation.
