Principle 4-20mA pressure sensor water level controller
Input type (Hydraulic pressure) liquid level transmitter adopt high performance diffused silicon
piezoresistive pressure sensor as measuring an>, 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
This product has the advantages of small volume, convenient use and installation, directly put int the water, that can measure liquid height from the surface to the end of the liquid level transmitter.
Features 4-20mA pressure sensor water level controller
