The US Gauge Model 575P submersible level transmitters are hydrostatic level products for rapid, reliable level measurement. The unit comes standard with CSA Intrinsically Safe approvals for a variety of different level monitoring needs including lifts stations, inventory tank measurement, ponds, lakes, rivers, landfills, reservoirs, or any type of water treatment facility including power plants, steel mills, mines, industrial chemical plants, refineries, and municipal water and wastewater treatment facilities.
The 575P indicates level by continuously measuring hydrostatic level pressure via its sensing element and transmitted by a 4-20 mA signal. This design provides exceptional linearity and repeatability, low hysteresis and long term stability. Installation is easy; simply lower the transmitter into the tank, well, or vessel. The unit can be calibrated to any measuring range needed, up to 690 feet.
The 575P submersible level transmitters has a 316 Stainless Steel housing. More still, the unit has a protective cage and Hastelloy C diaphragm for agitated liquid in sewage and industrial applications. Cable options include Teflon or polyurethane, and optional potting is available.
The 575P submersible level transmitter is manufactured in the USA.
