BPZK04-D Electronic Pressure Switch Introduction of differential electronic pressure switch Differential Pressure Transmitter
: 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.
