Yokogawa Electric Corporation 4176 Hybrid Chart Recorder

The Yokogawa 4176 Hybrid Chart Recorder is a panel- or bench-mounted instrument that logs process variables onto a 180 mm chart with optional electronic recall, providing a durable archival tool for industrial data acquisition. It accepts multi‑channel inputs including voltage, current, temperature, and pressure signals to monitor process conditions across industrial environments such as process plants, power generation facilities, manufacturing lines, and laboratory testing setups. Its hybrid recording method combines an analog chart with electronic backup (configuration dependent), delivering a continuous paper record for audits, troubleshooting, and operational analysis while displaying data on an analog chart with pen recording. The unit runs on 104–126 VAC power and stores information primarily on paper charts, with possible electronic recall depending on model. Mounting options include panel mounting or bench mounting to suit existing installations. Common replacements include Yokogawa µR10000 Hybrid Recorder, Yokogawa µR20000 Recorder, and DX1000 / DX2000 Paperless Recorder, aiding legacy system continuity. Status: Legacy / discontinued recorder series. Applications span oil & gas, chemical processing, power plants, and general manufacturing facilities requiring continuous process monitoring and data logging.
