The CorrTran MV corrosion-detection transmitters now deliver information wirelessly via the WirelessHART protocol. Users can determine the effectiveness of their corrosion inhibitors by detecting and correcting corrosion issues through upkeep and preventative maintenance.
Both WirelessHART and standard HART model CorrTran MV transmitters use a new algorithm of the LPR (linear polarization resistance), HDA (harmonic distortion analysis), and ECN (electrochemical noise) measurement for maximum corrosion-monitoring accuracy. The units automatically calculate and update the Stern-Geary value (B-value) due to changes in other process variables to maintain maximum accuracy. At the end of each measurement cycle, the corrosion rate and pitting value is calculated and made available in the form of a 4-to-20-mA HART signal.
The transmitters can direct or remotely mounted in general-purpose, intrinsically safe, explosion/flameproof, and Class I, Division 2 hazardous locations.
