CS15
Non-Clogging Submersible Pressure Transducer
About the CS15
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.

1
A flush diaphragm in Hastelloy C276 material prevents clogging while also surviving in some of the toughest environments.
2
A Kynar strain relief with Viton seals help prevent liquids from entering the sensor.
3
High corrosion resistance and superior strength make ETFE (Ethylene tetrafluoroethylene) an excellent cable jacket material for the CS15’s most common applications.
4
High strength 304 SS construction makes up the majority of the metallic construction including the heavy duty steel cage, housing (case), and 1/2″ MNPT conduit fitting.
Engineered For The Toughest Environments
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) make 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.
A high quality ETFE cable jacket exits the sensor, allowing for long term submersion in a wide variety of liquids.
