EMI/RFI protection
IP68 ratingThe 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 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, which prolongs the life of the transducer.
