The MS3011 is an automatic corrosion
transmitter capable of measuring and transmitting data from all types of 3-electrode
linear polarization resistance (LPR) corrosion probes.
Corrosion rate measurements are made using the linear polarization resistance technique. The instrument measures the current required to polarize the electrodes of a probe to a known potential. From the polarization potential and the measured current, polarization resistance can be calculated. Then, using Faraday’s law, instantaneous corrosion rate is calculated from polarization resistance.
The instrument offers measurement ranges as low as 0 to 0.5 mpy, and as high as 0 to 1000 mpy. The measurement cycle time is also adjustable. Both values are set using switches on the front panel of the instrument. This allows the instrument to be configured to almost any application.
Corrosion Rate is transmitted via current loop. This feature allows data from the instrument to be fed directly to any industrial process computer that accepts analog inputs. The current loop output has a switch-selectable range, making it compatible with most systems.
The MS3011 also offers a programmable alarm circuit. The alarm set-point is adjusted as a percentage of full scale, using a switch on the front panel. The alarm is capable of switching up to 115VAC at 5A, and offers normally-open and normally-closed contacts.
The instrument can be mounted in a standard 19-inch rack, using optional hardware. There is also an optional NEMA-12 weather-proof housing for field-mounting of the instrument.
