BPZK04 0.25%F.S Two Point Switch Digital Electronic Pressure Switch
BPZK04 Electronic Pressure Switch
Introduction of electronic pressure switch:
BPZK04 differential 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,
Product Features of Electronic Pressure Switch:
1. Can provide up to two control relay outputs, with the ability to set arbitrary relay values and states for precise and reliable control.2. Can be used to protect the system from too high or too low
pressure damage. When the pressure exceeds or falls below a set
threshold, the controller triggers the appropriate action, such as
closing the valve or stopping the pump.
3. Can be used to regulate the pressure in the system to ensure
that it remains within the set range. When the pressure deviates
from the set value, the controller will adjust the working state of
the actuator to bring the pressure back to the set range.
4. can be used to achieve precise control of the pressure in the
system. In conjunction with other control devices, such as flow
regulating valves, precise regulation and control of pressure in
complex industrial processes can be achieved.
5. plays an important role in the safety system. For example, in
steam boiler systems, pressure controllers can be used to monitor
and control steam pressure to ensure safe and stable system
operation.

Ordering tips
Ordering tips:
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.
