BPZK04-D Electronic Pressure SwitchIntroduction of differential electronic pressure switch: BPZK04-D differential electronic pressure switch is a fully digital
measurement and control product integrating pressure measurement,
point control display and transmission output. The two pressure
difference values are measured through the positive and negative
pressure ends and fed back to the field. The output 4-20mA standard
signal is displayed on the spot with two relays. When the pressure
reaches the set value, the relay is closed or disconnected to
control. Allows field use of keyboard to fine-tune parameters and
differential pressure control points.

2. 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.
