Corrosion Monitoring Transmitter Supports WirelessHART

Pepperl+Fuchs CorrTran MV Corrosion Detection Transmitters can now deliver information via the WirelessHART protocol.  This functionality is said to enable 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 problem.

"CorrTran MV is field-proven technology that represents a truly revolutionary approach to corrosion monitoring by taking corrosion evaluation out of the laboratory and bringing it into everyday process control. Now CorrTran MV takes this success to a new level with a simple, easy to-use two-wire transmitter operating on the industry standard four … 20 mA control basis and easily integrated HART protocol," says Kristen Barbour, product marketing manager, Pepperl+Fuchs.
 
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.  They also 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.
