Hengtong 4-20mA OEM Smart Pressure Switch Controller Transmitter Digital Pressure Sensor

Product Description

ZK04 4-20mA and pressure switch control
BPZK04 Electronic Pressure Switch
Introduction: BPK-ZK04 electronic pressure switch is a fully digital measurement and control product that integrates pressure measurement, point control display, and transmission output. It can be directly installed at the pressure measurement point in the field or on the control screen of the test bench. It allows on-site setting of parameters such as zero value, full-scale value, and contact pressure value using the keypad.
Product Features:Stainless steel structural design with versatile pressure interface options. with high-brightness LED pressure display.Powered 24VDC.Can provide up to two control relay outputs, with the ability to set arbitrary relay values and states for precise and reliable control.High accuracy.
Applications:
Measurement and control of pressure/differential pressure of fluid media in industries such as hydropower, metallurgy, and chemical engineering, for automatic control applications.

Ordering tips

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, and whether it comes with an RS485 interface.
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.
