Vacuum Digital Pressure Switch Air Negative Adjustable Control Mode 220V
The most popular in the market in the past few years is the electronic pressure switch, which is used to replace the electrical contact pressure gauge and is used in systems with high industrial control requirements. This pressure switch has a built-in precision pressure sensor. It amplifies the pressure signal through a high-precision instrumentation amplifier and collects and processes data through a high-speed MCU. Generally, it uses a 4-digit LED to display the pressure in real time and the relay signal is output. The upper and lower limit control points can be freely set. Low hysteresis, anti-vibration, fast response, stable and reliable, high precision (accuracy generally ± 0.5% FS, high ± 0.2% FS), the use of hysteresis settings can effectively protect against repeated actions caused by pressure fluctuations, protection control The equipment is a high-precision equipment that detects pressure and level signals and realizes pressure and level monitoring and control. The characteristics are: the electronic display is intuitive, with high precision and long service life. It is convenient to set the control point through the display screen, but the relatively high price requires power supply.
