Corrosion Data Delivered Wirelessly

April 7, 2010
CorrTran MV Corrosion Detection Transmitters—which can deliver multivariable outputs, including general and local corrosion rates and conductivity, from a single transmitter—can 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. 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. At the completion of each measurement cycle, the respective corrosion rate and pitting value is calculated and made available to plant personnel in the form of a 4-20mA Hart signal.Pepperl+Fuchs Inc.www.pepperl-fuchs.com330.486.0002
