Intelligent Float Level Transmitter
Summary
The UQD series intelligent float level transmitters are widely used for measuring and controlling liquid levels in viscous, dirty, flammable, explosive, corrosive, and other types of media. The transmitter consists of two main components: a measuring sensor mechanism and a transmitter unit. The measuring sensor features a spherical float, while the transmitter employs a torque balancing mechanism with a balance rod and counterweight, allowing the float to move freely with liquid level changes. When the liquid level shifts, the float's position changes, driving the main shaft to rotate. The shaft connects to the transmitter's angular displacement sensor, which converts the float's movement into electrical signals. An intelligent processor automatically switches direction and outputs 4-20mA signals via the HART protocol. This product is extensively used in industrial processes such as petroleum, chemical, metallurgy, power, and light industries for level measurement and control.
▲ Characteristic
◆ The appearance is beautiful, the structure is simple, and it is easy to disassemble and maintain.
◆ The working chamber and the wiring chamber of the transmitter are isolated from each other, which is safe and reliable.
◆ It is especially suitable for viscous, dirty, flammable, explosive and corrosive media.
◆ The intelligent signal processor is adopted, which can be directly adjusted the zero point and the range without manual switching.
◆ The measurement accuracy is high.
◆ LCD backlight display.
◆ Output 4-20mA with HART protocol.
