The BPZK04 electronic pressure switch is an all-digital control device that combines pressure measurement, control display, signal transmission, and output functions. It activates instantly to power connected equipment on or off when the pressure of non-corrosive gases or liquids reaches the predefined switching point. Compact and lightweight, it is ideal for installation in space-constrained environments including aircraft, ships, and vehicles. Featuring adjustable operating pressure and user-friendly precise control, the switch can be mounted directly onto 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 |
-
When selecting the product, please ensure its wetted materials are compatible with the medium being measured.
-
Please specify the power supply requirements, accuracy class, and set point(s) when placing an order.
-
The stainless steel diaphragm pressure controller offers a measuring range from 0–10 kPa up to 60 MPa.
-
For differential pressure measurement applications, ensure the differential pressure range is appropriately related to the allowable overpressure and maximum pressure ratings of the high and low pressure chambers to meet field requirements. To ensure safe and reliable operation, it is recommended to install a three-valve manifold between the measurement point and the transmitter.
-
To guarantee equipment reliability, lightning protection devices should be installed on-site, and both the product and power supply must be reliably grounded. Please inform our company at the time of ordering if special conditions apply, such as strong vibration, sudden shock forces, or strong electromagnetic/RF interference.
