Real time corrosion measurement transmitter
SmartCET Honeywell Process Solutions

The patented Honeywell SmartCET® corrosion transmitter uniquely provides on-line, real-time corrosion information that enriches the information in a process knowledge system (PKS). SmartCET interfaces to a DCS or PKS using a 4-20 mA signal with a HART protocol, allowing legacy system and Experion customers to have a direct method to bring the corrosion data into their system.

SmartCET gives plant operators access to time-trended general (uniform) corrosion rate, which can be correlated with plant process information. Also, it provides an indication of corrosion modality (localized or pitting corrosion) detection. Localized corrosion is responsible for approximately 70 percent to 90 percent of all corrosion-related equipment failures.

The SmartCET transmitter is available in two versions: a multivariable version and a single variable version. The multivariable version outputs a general (uniform) corrosion rate, a localized (pitting) corrosion indicator and two additional corrosion variables useful for further analysis.

SmartCET deploys a proprietary and patented automated, electrochemical multi-technique. The techniques applied include LPR in combination with two more recently developed and quantitative techniques: Electrochemical Noise (ECN) and Harmonic Distortion Analysis (HDA).
