Interface level transmitter is designed and certified in accordance with explosion-proof requirements. It is suitable for accurate measurement of process vessels and storage vessels in petroleum, chemical, electric power, steel, food, pharmaceutical and other industries.
Interface Level Transmitter can provide high-speed, reliable and high-precision continuous measurement in explosive gas environment. The output is in analog or digital form. The analog output form is two-wire 4-20mA+Hart; the digital output adopts RS485 (Modbus protocol) communication. When interface level transmitter working, it can be one or more floating balls. The floating ball can be suspended on the liquid-gas interface and liquid-liquid interface in the storage tank respectively, and move synchronously with them, WPX902 interface level transmitter realizes the real-time detection of the liquid level or interface of the liquid tanks.
