The BCS41 sensor is designed for high pressure, high temperature conductivity measurements and is an ideal choice for boiler control applications. Blowdown control, condensate monitoring, leak detection on heat exchangers and steam purity measurements are just a few of the many applications in which this rugged and reliable sensor can be used. Wetted materials are 316 stainless steel and PEEK. All possible leak paths through the sensor are double sealed with EPR O-rings for maximum on-stream reliability. Hot water is a severe environment for any elastomer and the front seals bear the brunt of chemical attack, allowing the back seals to remain relatively unaffected. This results in a sensor life which is more than double that expected of single sealed or epoxy sealed sensors. BCS42 this sensor has a small footprint for its high probe constant of K=20. Its size and economical pricing make it ideal for use in various OEM applications, such as skid mounted R.O. Systems, water treatment units, chemical dilutions and many more. Wetted materials are 316 stainless steel and TEFLON. The thermowell containing the temperature sensor in its tip is exposed directly to the stream, assuring rapid automatic temperature compensation for maximum accuracy. Process connections are ¾”NPT for insertion .
