GENERAL INFORMATION
The TRANSMITTER AECO 400 LPR monitor corrosion penetration in any environment (solid, liquid or gaseous) using the electrochemical law of potential deviation.
The transmitters are connected to LPR Probes by suitable Cables and are located near the Probes themselves.
Data can be transferred to the receiver Unit or to a Computer (laptop or notebook IBM compatible) or to a Multimate 41 equipment either through a cable RS232 or, to maintain the intrinsically safe design of the unit, via an optical, infrared, RS232 Link.
The measurement is carried out timed and memorised in a internal memory.
The rates of measures are re-programmable 0.1-1000 hours.
Data and set-up are retained automatically for a minimum period of 30 Years
A single instrument can be set to measure one of many LPR probes: each Probe can be distinguished by a unique TAG number and measures are memorised in a non-volatile memory with Tag number & Date/time associated.

OPERATING PRINCIPLE
The TRANSMITTER AECO 400 LPR reads the electrical resistance of the corroding electrode-electrolyte interface. The polarization resistance is measured as the ratio of the applied DC potential to the flowing current and is constant over a small range (<20mV) and is related to corrosion rate.
