ABB IM/C1900-OGR Operating Guide Recorder

Product Description

The ABB IM/C1900-OGR is a C1900 Series Circular Chart Recorder, specially designated as an Operating Guide Recorder. It is designed to continuously record one or two process variables—such as temperature, pressure, or flow rate—on a 10-inch circular chart, providing a clear, analog representation of process behavior over time. The OGR version includes enhanced guidance features for operator reference, such as preset alarm thresholds and operator instructions on the chart, making it ideal for critical or regulated processes.
