CorrTran MV corrosion monitoring transmitter
Apr 21, 2010
CorrTran MV corrosion monitoring transmitterThe CorrTran MV Corrosion Detection Transmitters, known for their ability to deliver multivariable outputs, including general and local corrosion rates and conductivity, from a single transmitter, now deliver that information wirelessly via the WirelessHART protocol. This functionality enables users to determine the effectiveness of their corrosion inhibitors, and to detect and correct corrosion issues through upkeep and preventative maintenance, before they become a costly problem. 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. They automatically calculate and update the Stern-Geary value (B-value) due to changes in other process variables to maintain maximum accuracy. At the completion of each measurement cycle, the respective corrosion rate and pitting value is calculated and made available to the plant personnel in the form of a 4…20 mA HART signal. CorrTran MV transmitters can be located in general purpose, intrinsically safe, explosion/flame proof and Class I, Division 2 hazardous locations, and are suitable for direct or remote mounting. New models feature the same design and dimensions as earlier versions, and can be retrofitted to older units.
