Description PL301 Submersible level transmitter
The PL 301 series is a highly reliable and accurate level sensor.
Widely used in liquid pressure and liquid level measurement, such
as water, oil and other low corrosive liquids.
SU304 or 316L stainless steel construction, quality oil filled
pressure sensing device, dedicated amplifier and V/I inverter
circuit board, easy external programmable zero and full range
calibration.
The frequency converter can be equipped with wear-resistant,
oil-resistant, acid-alkali resistant, high-strength breathable
cable according to the different use environment on site.
The PL301 submersible level transmitter/hydrostatic level sensor is
designed for use in rivers, reservoirs, water tanks, boreholes,
boats and channels. Because of their long-term immersion protection
up to 100 meters, they are also ideal for measuring pressure in
underwater pipelines and ships.
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 case and
waterproof cable, can be directly into the water/oil/tank or
reservoir for level measurement. The measurement range ranges from
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. The output signal is
4-20mA/0-5V/RS485, and the power supply is 24V/12V. Cable type and
connection type are also customizable.
Submersible level sensor is essentially a pressure sensor for
measuring liquid level. According to the principle that the static
pressure of the measured liquid is proportional to the height of
the liquid, the static pressure is converted into electrical
signals by isolated diffused silicon sensor or ceramic capacitive
pressure sensor. The signal is converted to standard signal after
temperature compensation and linear correction. Submersible level
sensors are generally used for liquid level measurement in
petrochemical, metallurgy, electric power, pharmaceutical, water
supply and drainage, environmental protection and other media.
