Description PL301 Submersible level transmitter
The PL301 Series Submersible Level Sensor provides continuous level
measurement for both corrosive and non-corrosive liquids. These
submersible hydrostatic transmitters have been designed for the
toughest industrial applications. Unlike ultrasonic level
transmitters, our liquid level sensors are completely unaffected by
any foam, vapor, turbulence or condensate in the tank.
The PL301 Series Tank Level Sensor works by sitting at the bottom
of the tank and measuring the head pressure of the liquid pushing
down on its stainless steel sensing diaphragm. The only submersible
level sensor with an integral molded weight to ensure the sensor
will remain at the bottom and you will always receive an accurate,
reliable reading.
Submersible level sensor adopts 304 stainless steel housing and
waterproof cable, can be put in water/oil/fuel tank or reservoir
directly for liquid level measurement. The measuring range can be
0-1m/0-3m/0-5m/0-10m ~ 0-500m. Liquid level sensor has optional
accuracy 0.5%FS or 0.3%FS, output signal 4-20mA/0-5V/RS485, power
supply DC 24V/12V. The cable type and connection type are also
customizable.
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.
