MS2540 Receiver / Repeater

The MS2540 Receiver is designed to be used with our ER and LPR current loop transmitters to provide a single-channel corrosion monitoring system. The MS2540provides a local display of the probe and transmitter data. Additionally the MS2540 can repeat the information to a plant control room via RS-485 Modbus.

The MS2540 utilizes a color touch screen to displayinformation and present user controls. The unit ispowered by 100-240 VAC, and provides the 24 VDCsupply for powering the transmitter's 4-20 mA loop.The receiver processes the 4-20 mA signal to provide a digital readout of the cumulative metal loss and the probe corrosion rate based on the monitoring period set by the user (48 hours, 7 days, 15 days or 30 days).

This method finds a wide variety of applications since it can be used in conductive and nonconductive environments such as petroleum, chemical, water, soil, or even atmosphere. The new high-resolution measurement of the MS4500E-HC detects smaller increments of metal loss, providing faster response than traditional ER instruments.

After taking a reading, the instrument displays metal loss in mils and corrosion rate in mils per year (mpy). The reading can then be stored to memory or discarded. All stored readings are automatically time and date stamped. Readings are stored to non-volatile Flash memory which retains data without the need for a battery backup.

The MS4500E-HC can store 16,000 readings per probe on up to 250 different probes (4 million total). Stored data can be downloaded directly to a non-certified USB Flash drive in non-hazardous areas or to a certified USB Data Transfer Unit in hazardous areas. Data can also be downloaded to a PC through a certified USB Barrier in non-hazardous areas. Data can be opened and charted using the provided Corrosion Data Management software, or can be imported into any standard data analysis (spreadsheet) program such as Microsoft Excel. Data can also be reviewed and charted on the instrument’s LCD display for quick reference.
