The Myron L Model CS41 sensor was designed for high pressure, high temperature Conductivity & Resistivity 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 of construction are 316 stainless steel and Kel-F®†  or Teflon®*, depending on the range of temperature required. All possible leak paths through the sensor are double sealed with EPR O-rings for maximum onstream reliability.

Hot water is a severe environment for any elastomer, and the first O-ring bears the brunt of chemical attack, allowing the second O-ring to remain relatively unaffected. The result is the sensor life is more than double what can be expected of single sealed, or epoxy sealed units. 

Probe constants of 0.05, 0.1, & 1.0 are available, which will cover the ranges in most boiler related applications.



• Measures conductivity or resistivity directly in process temperatures up to 205ºC.
• Dual O-ring seals used on all versions for high on-stream reliability.
• Boiler condensate and blowdown
• Explosion-proof enclosure
