The Division 2 / Zone 2 corrosion
data logging system complements the manufacturer’s online corrosion monitoring
transmitter, allowing users to access real-time corrosion data via Ethernet,
USB, SD card, or locally via videographic chart recorder. The corrosion data
logging system is packaged in a portable, stainless steel enclosure weighing
less than 20 lbs. The corrosion data logging system includes a HART loop
converter. This device receives HART data from the corrosion monitor and delivers
three distinct 4-20 mA outputs that represent general corrosion, localized
corrosion, and conductance. These three variables can then be recorded and
displayed on a paperless data recorder that features a full color touch screen
display, up to 16 analog inputs, multiple types of media retrieval, and a Class
I/Div 2, Zone 2 Ex-hazardous rating. A Type 4X stainless steel enclosure allows
for the most severe of installations. The lightweight construction also permits
easy mobility for the system to be moved from one location to another, where a
PLC/DCS might not be available.
