ZK04 4-20mA and pressure switch control
BPZK04 Electronic Pressure Switch
Introduction: BPK-ZK04 electronic pressure switch is a fully digital measurement and control product that integrates pressure measurement, point control
display, and transmission output. It can be directly installed at the pressure
measurement point in the field or on the control screen of the test bench. It
allows on-site setting of parameters such as zero value, full-scale value, and
contact pressure value using the keypad.
- Stainless steel structural design with versatile pressure interface
options.
- with high-brightness LED pressure display.
- Powered 24VDC.
- 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:Measurement and control of pressure/differential pressure of fluid
media in industries such as hydropower, metallurgy, and chemical
engineering, for automatic control applications.

1. When selecting the product, please ensure that the measured
medium is compatible with the contacting parts of the product.
2. When placing an order, please specify the power supply, accuracy
grade, number of control points, and whether it comes with an RS485
interface.
3. The measurement range of the flat diaphragm pressure controller
is 0~35KPa...20MPa.
4. For users selecting differential pressure measurement, pay
attention to the relationship between the differential pressure
range and the allowable overpressure and maximum pressure of the
high and low pressure chambers, and ensure it aligns with the
requirements of the field application. To ensure the safe and
reliable operation of the product, it is recommended to install a
three-valve manifold between the measuring point and the
transmitter.
5. To ensure the reliable operation of the product, it is
recommended to install lightning protection devices at the site and
ensure that the product and power supply are reliably grounded. For
special requirements such as strong vibration, instantaneous impact
force, strong electromagnetic interference, and radio frequency
interference, please inform our company and specify them in the
order.
