The BPZK04 electronic pressure switch is an all-digital control device that combines pressure sensing, operational interface, and signal transmission. It can serve as an alert mechanism when pressure levels in non-corrosive gases or liquids reach a threshold, or act as an electrical contact switch within pressure regulation systems. Its small form factor and low weight allow for deployment in space-constrained environments such as aircraft, vessels, and automotive applications. Furthermore, it provides benefits including configurable set-point pressure, user-friendly and precise adjustment, and straightforward integration into on-site piping systems.
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 |
- When choosing products, ensure their wetted materials are compatible with the media being measured.
- At the time of order placement, please indicate the power supply requirements, accuracy class, number of control outputs, and whether an RS485 interface is included.
- The measuring span for flush diaphragm pressure controllers extends from 0–35 kPa up to 20 MPa.
- For customers opting for differential pressure measurement, care must be taken to correctly correlate the differential pressure range with both the allowable overpressure limit and the maximum working pressures of the high- and low-pressure sides to fulfill on-site application needs. To ensure safe and reliable performance, installation of a three-valve manifold at the connection between the sensor and the process is recommended.
- To maintain operational reliability, lightning arresters should be installed on site, and both the instrument and power supply must be properly grounded. Should specific conditions exist—such as severe vibration, sudden shock loads, or high levels of electromagnetic or radio frequency interference—please inform our company at the time of ordering.
