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.
