Pressure Switch With 2 To 4 Point Controller And 4-20mA Electronic
Pressure Switch
BPZK Electronic Pressure SwitchIntroduction:BPK-ZK 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 choosing a product, please ensure that the medium to be
measured is compatible with the contact parts of the product.
2.When placing an order, please specify the power supply, accuracy
grade, number of control points, and whether it is equipped with an
RS485 interface.
3. The measurement range of the flat diaphragm pressure controller
is 0 to 35 kpa... 20MPa.
4. For users who choose differential pressure measurement, it is
necessary to 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
that it meets the requirements of on-site application. To ensure
the safe and reliable operation of the product, it is recommended
to install a three-valve manifold between the measurement point and
the transmitter.
5. To ensure the reliable operation of the product, it is
recommended to install lightning protection devices on site and
ensure that the product and power supply are reliably grounded. In
case of special requirements such as strong vibration,
instantaneous impact force, strong electromagnetic interference,
radio frequency interference, etc., please inform our company and
specify them in the order.
