The BPZK04 electronic pressure switch is a fully digital control product that integrates pressure measurement, control display, and transmission output. It can function as a signal device when the pressure of non-corrosive gases and liquids reaches a limit value, or as a circuit contact switch for a pressure regulator. The compact size and lightweight design make it suitable for installation in aircraft, ships, and vehicles with intensive space requirements. Additionally, it offers advantages such as adjustable operating pressure, convenient and accurate control, and direct installation in field pipelines.
Product Features of electronic pressure switch:
- Stainless steel structural design with versatile pressure interface options.
- with high-brightness LED pressure display.
- Powered 24VDC or 24VAC.
- Can provide up to two control relay outputs, with the ability to set arbitrary relay values and states for precise and reliable control.
- High accuracy.
Applications of electronic pressure switch:
Measurement and control of pressure/differential pressure of fluid media in industries such as hydropower, metallurgy, and chemical engineering, for automatic control applications.

| Ordering tips of Electronic Pressure Switch |
1,When selecting products,please make sure they are suitable for contacting parts with measured media.
2,When placing an order,please specify power supply,precision level,number of control points,and whether it includes RS485 interface.
3,The measuring range for flat diaphragm pressure controllers ranges from 0~35KPa to 20MPa.
4,For users who choose differential pressure measurement,attention should be paid to ensuring that there is a proper relationship between differential pressure range with allowable overpressure as well as maximum pressures in high- & low-pressure chambers so as to meet field application requirements.To guarantee safe & reliable operation of this product,it's suggested installing a three-valve manifold between measuring point & transmitter.
5,To assure reliable operation,it's advised installing lightning protection devices on-site&ensuring dependable grounding for both product&power supply.If there're special demands like intense vibration,instantaneous impact force,strong electromagnetic or RF interference,pls notify our company when placing orders.
