Description PL301 Submersible level transmitter
For corrosive media applications such as seawater or leachate, especially in landfills, we offer advanced dual phase stainless steel submersible level transmitters with extremely high corrosion resistance.
Submersible level sensor with 304 stainless steel housing and waterproof cable, can be directly into the water/oil/tank or reservoir for level measurement. Measuring range :0 to 1m, 0 to 3m, 0 to 5m, 0 to 10m, 0 to 500m. The accuracy of the liquid level sensor is 0.5%FS or 0.3%FS. Output signal 4-20mA/0-5V/RS485, power supply 24V/12V. Cable type and connection type are also customizable.
Submersible level sensor is essentially a pressure sensor used to measure liquid level. According to the principle that the static pressure of the liquid under test is proportional to the height of the liquid, the static pressure is converted into electrical signal by the isolated diffusion silicon sensor or ceramic capacitive pressure sensor. The signal after temperature compensation and the linear correction is converted into a standard signal. Submersible level sensor is generally used in petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection and other media liquid level measurement.
The submersible level sensor essentially is a pressure transducer that measures the liquid level. Based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid, it uses an isolated diffused silicon sensitive element or a ceramic capacitive pressure sensitive sensor to convert the static pressure into the electrical signal. The electrical signal is converted into a standard electrical signal after temperature compensation and linear correction. Submersible level sensor is generally suitable for liquid level measurement of various media in petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage and environmental protection.
The submersible hydrostatic level transmitter PL301 has been designed for continuous liquid level monitoring in water wells, reservoirs, tanks, boreholes, rivers and other liquids.
The submersible unit measures the static pressure of the liquid column above the transmitter and transmits a current signal proportional to the water column to the instrumentation above.
The highly stable 316L stainless steel diaphragm sensor is fully compatible with raw or chlorinated water and most semi-corrosive liquids.
A special ventilation cable is provided to compensate for changes in atmospheric pressure, and it accurately transmits measured liquid levels. The cable lengths associated with the application can be determined to the desired range at the time of purchase or can be adjusted by the customer at the site of the application.
The submersible static pressure liquid level transmitter PL301 is specially designed for continuous monitoring of liquid level in Wells, reservoirs, water tanks, boreholes and rivers.
