Liquid level sensor
Nov 02, 2016

Liquid level sensors (static pressure liquid level transmitter level//liquid level sensors/water level sensor) is a pressure sensor to measure liquid level. Submersible level transmitter static pressure (gauge) is based on the measuring the static pressure and the principle of proportional to the height of the liquid, adopts the foreign advanced isolated Silicon sensing element or pressure-sensitive ceramic capacitance sensor converts the static pressure into electrical signals, and temperature compensation and linear correction, converted into standard signals (typically 4~20mA/1~5VDC).


Is divided into two class: a for contact type, including danfalanjing pressure/double method blue poor pressure liquid bit variable sent device, floating ball type liquid bit variable sent device, magnetic liquid bit variable sent device, input type liquid bit variable sent device, electric within floating ball liquid bit variable sent device, electric buoy liquid bit variable sent device, capacitor type liquid bit variable sent device, magnetic to telescopic liquid bit variable sent device, paternity clothing liquid bit variable sent device,. Second is non-contacting, divided into ultrasonic level transmitters, radar level transmitters.


Submersible level transmitter static pressure (gauge) applied to petroleum, chemical, metallurgy, electric power, pharmaceutical, water supply and drainage, and environmental protection systems and liquid level measurement of the various media. Compact structure, simple set-up and flexible installation provides convenience for users to easily use the. 4~20mA, and 0~5V, 0~10mA and other standard signal output mode optional as required by the user.


Using hydrostatic measuring liquid level, is an important application of pressure sensor. With special cable and dedicated with a ventilation duct sealing technology, ensuring the water tightness of the sensor, makes reference to a pressure Chamber connected with the environmental pressures, so as to ensure high measurement precision and high stability.
