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

ZK04 4-20mA and pressure switch control BPZK04 Electronic Pressure SwitchIntroduction: 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.   Performance ParametersMeasurement Range-100kPa…0kPa ~ 10kPa…100MPa0-10KPa~2MPa(Differential Pressure)Pressure TypeGauge Pressure, Absolute Pressure, Sealed Pressure,Differential PressureOverload≤ 1.5 times of the rated rangeAccuracy @ 25ºC±0.25% (Typical) ±0.5% (Maximum)Long-Term Stability±0.3%F.S/yearZero Point Temperature Drift±0.02%F.S/ºC(≤100KPa) ±0.01%F.S/ºC(>100KPa)Full Scale Temperature Drift±0.02%F.S/ºC(≤100KPa) ±0.01%F.S/ºC(>100KPa)Compensation Temperature0-50ºC(0-10KPa, 0-20KPa) ,0-70ºC ,-10-70ºCOperating Temperature-20ºC~80ºCStorage Temperature-40ºC~120ºCHousing Material1Cr18Ni9TiDiaphragm Material316LInsulation Resistance100MΩ 100VDCRelay Control1-2 channels of control or electronic switch quantity controlContact LifeExceeds 100,000 cyclesDisplay Range-1999~9999Installation Methodvertical axis installationExplosion-proof RatingIntrinsically SafeProtection RatingIP65Weight~0.3kgOutline Construction  DimensionOrdering tips1. 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.    Q&A1.Q: What are the features of your pressure sensor transmitters?   A: High precision, durability, and excellent performance.
