Linear Polarization Resistance (LPR) Transmitter Model 9020 Features  Two-Wire Loop Powered  Continuous Corrosion Rate  Second Loop for Imbalance Measurement  Extended Operating Range  Available as an OEM Module The Model 9020 Linear Polarization Resistance (LPR) Transmitter is ideal for accurately monitoring corrosion rate in water systems ranging from high conductivity cooling water and seawater to low conductivity condensates. Power is supplied to the transmitter and the corrosion rate data obtained over a single pair of wires which facilitates installation and operation. The 9020 LPR Transmitter is mounted in a NEMA‐4X (IP 66) weatherproof enclosure suitable for field mounting; or for OEM users, the 4‐20 mA. The Loop LPR Transmitter Module can be easily installed in existing systems or tower controllers to provide continuous corrosion rate monitoring. An independent second current loop provides the imbalance measurement which is a sample of Electrochemical Current No
