The CS15 non-clogging submersible pressure transducer is designed for liquid level measurement in turbulent tanks and tanks with viscous medias such as wastewater lift stations. A Hastelloy C276 diaphragm, stainless steel construction and an ETFE cable jacket allow for installation in a wide variety of liquids. The heavy-duty steel cage anchors the sensor at the bottom of the tank to ensure accurate level readings as well as acting as a barrier between solids in the tank and the flush diaphragm of the sensor. A vent tube runs the length of the cable and quickly equalizes the barometric pressure within the sensor body. The CS15 is available in various output signals including 4-20mA for long-distance transmissions and voltage outputs for low power, low current consumption applications.
The CS15 Non-Clogging Submersible Pressure Transducer was carefully engineered to withstand some of the toughest environments. With a thickness of 1 to 1.5 mils, the diaphragm is the thinnest component of the transducer. To help protect this critical component, Hastelloy* C276 (UNS N10276) is the standard diaphragm material. This material is a super nickel-molybdenum-chromium alloy offering excellent corrosion resistance, prolonging the life of the transducer. 300 series stainless steel (316L and 304) makes up the remaining metallic construction including the heavy-duty steel cage, housing (case), and 1/2″ MNPT conduit fitting. Precision TIG welds along with a Kynar strain relief and Viton seals prevent liquids from entering the sensor, resulting in an IP68 rating.
