9020 CORRATER® LPR Continuous Corrosion Rate Transmitter
The Model 9020 CORRATER® 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 CORRATER® Transmitter is mounted in a NEMA- 4X (IP 66) weatherproof enclosure suitable for field mounting; or for OEM users, the 4-20 mA. Loop CORRATER® 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 Noise (ECN) between the electrodes. The ECN or imbalance current is related to pitting corrosion activity and inhibitor film stability. |
