MS3600L LPR Data Logger |
View data sheet (PDF)
Intrinsic Safety Certificate |
Metal Samples’ MS3600L is a battery‐powered, intrinsically safe, remote data logger capable of measuring and storing data from Linear Polarization Resistance (LPR) corrosion probes. The instrument is microprocessor‐based and features a simple, menu‐driven interface.
The MS3600L data logger measures general corrosion, localized corrosion (pitting), and conductance, and stores that information. It utilizes state‐of‐the‐art algorithms and data analysis techniques to accurately measure general corrosion rate and pitting. Harmonic distortion analysis (HDA) is applied to improve the performance of the industry‐accepted linear polarization resistance (LPR) technique used to measure corrosion rate. |
|
To further enhance the performance, an application‐specific Stern‐Geary variable (B value) is calculated
and updated every measuring cycle. There is no need to manually update the B value because of process changes. During the measurement cycle, the data logger also performs an automated electrochemical
noise (ECN) measurement, which in combination with the corrosion rate data can provide a measurement
of localized corrosion (pitting). The data logger works with Metal Samples' two-electrode and three‐electrode LPR probes. Probes are available in a variety of mounting types and materials to suit almost
any type of installation.
The MS3600L takes probe readings on a user‐programmable logging interval. Readings are time and date stamped as they are taken, then stored to memory. Between readings, the instrument remains in
a “sleep” mode to conserve main battery power. The instrument’s memory is capable of storing more than 100,000 readings and is stored in non‐volatile Flash memory.
Stored data can be uploaded to any PC as a comma‐delimited ASCII text file. Because the data is in ASCII text format, it can be imported into any standard data analysis program such as Microsoft Excel. Data can also be reviewed on the instrument’s LCD display for quick reference.
Stored data can be downloaded directly to a certified data storage device. This eliminates the need to remove the MS3600L from its site, or to bring a laptop PC to the site. This can be particularly useful when collecting data from multiple MS3600L data loggers. And since the MS3600L is intrinsically safe, data can be downloaded from the MS3600L even in hazardous locations.
The MS3600L also offers an optional 4‐20mA current loop output. This feature allows data from the instrument to be fed directly to any industrial process computer that accepts analog inputs.
The instrument is housed in a stainless steel NEMA 4X / IP 66 enclosure, and all external connections are weather‐proof. This makes the MS3600L suitable for use in almost any indoor or outdoor environment. |
