Principle, structure
The KCP20 intelligent pressure switch is equipped with a high-precision instrument amplifier to amplify pressure signals and a built-in temperature sensor for temperature compensation. It is a high-precision device that detects pressure and liquid level signals and achieves pressure and liquid level monitoring. Equipped with two built-in relays, it can meet the requirements of high and low point control for various gases and liquids. At the same time, it can achieve multiple operational functions such as resetting, calibration, changing display units, and setting hysteresis. The shell adopts an all metal structure, and the pressure sensing film adopts a stainless steel 1.4435 (316L) core, with stable performance.

characteristic
4-digit display of current pressure or liquid level value; The pressure or liquid level can be set according to one's own needs.
Dual relay output, the alarm point can be set arbitrarily within the range, and there is no dead zone adjustment.
Three pressure units are available: Bar, PSI, and Kpa.
High precision, low hysteresis, fast response, stable and reliable, easy to adjust.
application
Applied to industrial process sites such as construction machinery, hydraulics, electricity, environmental protection, automation control, hydraulic and pneumatic systems.
