Conductivity
Properly understood and applied, conductivity is probably simpler to operate and maintain than any other analytical measurement. Each type of sensor has certain applications for which it is best suited. Most applications decisions involve the sensor more than the instrument. Modern instruments are so featured-packed that they will cover almost any application, but not so the sensors. They are where the measurement system meets the process.
CS41 Conductivity Sensors
- Measure conductivity directly in process temperature up to 205ºC @ 250 PSIG
- O-ring seals used on all versions for high on-stream reliability
- Boiler condensate and blowdown control without coolers
The Model CS41 sensor was 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.
Application Notes
Wetted materials of construction are 316 stainless steel, PEEK, and EPDM o-rings. All possible leak paths through the sensor are double sealed with 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. The result is that sensor life is more than double what can be expected of single sealed, or epoxy sealed units.
