Pyxis CR-300 Wired LPR Corrosion Rate Sensor

LPR Corrosion Sensors vs. Corrosion Coupons:

LPR corrosion rate monitoring is a valuable tool that can be easily and affordably deployed to provide both general and localized corrosion measurements instantly. There is a common industrial misnomer that the use of inline LPR corrosion sensors should be identical to corrosion coupons. The LPR Corrosion level represents the real-time electrochemical measurement of corrosion. Measurements gathered from the CR-200 are instant & represent “real-time conditioning” on an MPY scale based on the metallurgy being assessed.

The CR-300 corrosion rate sensor is ideal for cooling and process water treatment monitoring where robustness and affordability are a must. The sensor utilizes the linear polarization resistance (LPR) method to produce a raw signal. The raw signal is conditioned, amplified and digitized directly in the sensor itself. This avoids the interferences and attenuation of the raw signal caused by long distance wiring needed for other corrosion sensors. Our corrosion sensors measure sample water conductivity directly and compensate for the conductivity impact on LPR measurement. These unique product characteristics make the Pyxis Lab® LPR superior in performance and accuracy. In addition to the LPR measurement used to obtain the general corrosion rate, the CR-300 sensor also measure for electrochemical noise. The measured noise data is used to calculate an index to quantify the localized corrosion rate also referred to as pitting.
