BPZK04-D Electronic Pressure Switch Introduction 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.

| Ordering tips of electronic pressure switch |
1. When selecting the product, please ensure that the measured medium is compatible with the contacting parts of the product.
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.
