OW740 pressure type liquid level transmitter

OW740 pressure type liquid level transmitter, the sensitive device is installed at the lower end of the relay box, and the input component is the balance cover. The two are connected by a pressure guiding pipe (pressure guiding pipe), and the pressure of the liquid column is indirectly transmitted to the sensitive component through the air conduction through the pressure guiding pipe, thus avoiding direct contact between the sensitive component and the measured medium

OW740Pressure type liquid level transmitter, the sensitive component is installed at the lower end of the relay box, and the input component is a balance cover. The two are connected by a pressure guide pipe (pressure guide), and the pressure of the liquid column is indirectly transmitted to the sensitive component through the air conduction through the pressure guide pipe, thus avoiding direct contact between the sensitive component and the measured medium. Not only suitable for measuring ordinary water, but also for liquid level measurement in special occasions such as high temperature, viscous, corrosive media. Widely applicable in fields such as chemical engineering, metallurgy, power plants, water conservancy, urban water supply, and industrial wastewater.
