BPZK03 intelligent pressure controller
DescriptionBPZK03 digital pressure controller combine pressure measuring,
display, control & transmit together, with RS485 communication
interface. It can utilize RS485 bus to achieve network, digital
signal transmitting and long-distance parameter setting &
calibration. It can set the zero output ,span output, ,pressure of
contact point and control pressure with key at scene.

2. When placing an order, please specify the power supply, accuracy
grade, number of control points.
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.
