4-20mA Electronic Pressure Switch Multi Point High Precision Digital Pressure Switch
BPZK01 4-20mA Multi-Point Electronic Pressure Switch Control Digital Switch
BPZK01 Electronic Pressure Switch
Introduction OF Electronic Pressure Switch :
BPK-ZK01 digital electronic pressure switch is a collection of pressure measurement, display, output, control in one of the intelligent digital pressure measurement and control products. The product is an all-electronic structure, the front end adopts an oil-filled piezoresistance pressure sensor with an isolation film, the output signal is amplified by A high-precision, low-temperature drift amplifier, and is sent to A high-precision A/D converter, which is converted into a digital signal that can be processed by a microprocessor, and the signal is controlled by two switches through operational processing to measure and control the pressure of the control system. The intelligent pressure controller is flexible, easy to operate, easy to debug, safe and reliable.

| 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. 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.
