UHS series float liquid level transmitter


UHS magnetic float liquid level transmitter can measure liquid level or interface continuously. The differential density of the two kinds liquid isn’t less than 0.1g/cm3 when the interface is measured. UHS transmitter transfer the level information to standard 4~20mA.DC current signal to output. If matched with CH series digital display alarm device, UHS can support the remote measurement, adjustment, control, or alarm of liquid level and interface in petroleum, chemical, textile, food, making wine, electric power, pharmacy, shipping, and water treatment etc..  

*Two-wire system
*Simple structure and reliable performance
*Simple installation and convinent maintenance
*Resistance to corrosion and moisture resistance
*Optional LED digital field indicator

Work principle
UHS magnetic float liquid level transmitter is based on the rules of buoyancy and magnetic coupling. As the liquid level rises or falls in the vessel, the power of permanent magnet in the float actuates reed switch in chief rod to close the reed switch in responding position. Electrical signal proportion to liquid level can be got , and transferred by circuit to standard 4~20mA DC signal.
