Hydrostatic level transmitter PS-UPLH
PS-UPLHSubmersible hydrostatic level transmitter for continuous liquid level measurement in wells, tanks, open vessels and water bodies, based on hydrostatic pressure.
Description
PS-UPLH is a submersible hydrostatic level transmitter that uses the dependence of hydrostatic pressure on liquid column height. The sensor sits at the bottom of the media and converts pressure into a unified 4–20 mA or 1–5 V output.
The fully sealed IP 68 housing with a stainless steel diaphragm is resistant to water, corrosion and aggressive media. The cable gland is rated for prolonged submersion up to 100 meters deep.
The device suits water intake wells, fire reserve tanks, wastewater treatment storage, open water bodies, fuel vessels and any application requiring simple, reliable level monitoring.
