Level measurement water level float switch
Principle of water level float switch :
Input type (Hydraulic pressure) liquid level transmitter adopt high performance diffused silicon piezoresistive pressure sensor as measuring element, after the high reliability of amplification circuit and precise temperature compensation, convert the gauge pressure or absolute pressure of the measured medium into standard voltage or current signals.
This product has the advantages of small volume, convenient use and installation, directly put into the water, that can measure liquid height from the surface to the end of the liquid level transmitter.
Feature of water level float switch :
Use advanced circuit processing technology, stable performance and high sensitivity
A variety of range, maximum measuring 200m (Water column pressure)
Adopting the 316L stainless steel diaphragm, applicable to a variety of measuring medium
Flexible configuration, select different configuration according to requirements.
Reverse polarity and overvoltage protection
Shock and lightning protection design
Laser trimming resistance temperature compensation, zero and range can be adjusted on site
Anti-Corrosion, suitable for a variety of medium
Overload and strong anti-interference ability, stable performance
Application of water level float switch :
Industrial site level measurement and control
City water supply and sewage treatment
hydrological monitoring of Petroleum, chemical industry, power plant industry
Level measurement and control of reservoirs, DAMS, water and electricity construction, etc
