Multiplexed LPR Field Unit Transmitter

One function for corrosion monitoring

The CHxxLPR Transmitter 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 141DL 14xER/LPR equipment either through a cable RS232 or 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 (CH01LPR) or many (CHxxLPR multiplexed) 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.

The CHxxLPR Transmitter 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.

• Software controlled, reprogrammable of the probe readings, upon simple operator commands via a portable PC, or our mULTIMATE 141DL 145ER/LPR equipment.
