Rugged CSX2 Conductivity Sensor Ideal For High Pressure, High Temperature Application
Boiler Control Applications, Blowdown Control, Condensate Monitoring, Leak Detection on Heat Exchangers, Steam Purity Measurements
Engineers in search of a rugged conductivity sensor for high pressure, high temperature environments will find that the new Electro-Chemical Devices (ECD) offers maximum reliability and a dramatically increased usable lifetime for harsh industrial processes.
The Model CSX2 is a two-electrode sensor that measures electrolytic conductivity at a range of 1.0-50,000 µS. It is designed for high temperature service up to 200°C at pressures of 250 psig. At temperatures below 100°C, the CSX2 is rated for pressures up to 400 psig.
The Model CSX2 features rugged construction with a 316 stainless steel outer body and center electrode, separated by a PEEK® (poly ether ether ketone) internal insulator. All possible leak paths are double-sealed with EPR O-rings for maximum on-stream reliability. Industrial hot water processes are a severe environment for any elastomer, and the EPR front O-ring seals bear the brunt of the chemical attack to allow the back seals to remain relatively unaffected. This redundant design increases the reliability of the CSX2, dramatically increasing the usable lifetime of the sensor in harsh applications to reduce instrument maintenance requirements and total lifecycle costs.
With its rugged design and superior accuracy, the CSX2 provides highly accurate and reliable conductivity measurement in a wide range of demanding industrial process plant applications. It is suitable for use in petrochemical refining, electric power generation, food/beverage, metals/mining or anywhere high pressure steam boilers are in use.
The CSX2 features a weather-resistant aluminum junction box that allows easy access to the terminal strip or the signal conditioner. The junction box is both explosion-and weatherproof and features a 0.75-inch FNPT connection. It includes a low temperature (80°C) 0.5-inch polyamide cable gland with reducer bushing.
The signal conditioner amplifies the conductivity signal, allowing noise-free transmission for hundreds of feet. A wide range of signal conditioners are available for the CSX2 sensor to optimize the conductivity measurement at specific ranges. The signal conditioner can be mounted in the integral junction box at temperatures below 70°C or located in the instrument or remote junction box at higher temperatures.
The measurement of conductivity and resistivity in liquid water-based solutions is an essential requirement in a wide range of industrial processes. Conductivity and resistivity measure the electrical conductivity of a solution, which correlates to the purity of the water or the amount of dissolved ions in the liquid.
Accurate, reliable conductivity data is important when either recycling water for re-use within the plant to protect sensitive equipment and/or when discharging water from the plant into wastewater treatment systems. The data helps ensure the effluent meets local, state and federal water quality standards to avoid plant shutdowns and costly fines.
