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.
