Yokogawa Electric Corporation 437024 Chart Recorder

The Yokogawa 437024 UR1800 Chart Recorder is an industrial data‑acquisition instrument that records process variables such as temperature, pressure, and electrical signals on a 180 mm wide chart. It supports 1–4 pen channels or up to 24 dot channels (model dependent) with analog pen or dot printing, and accepts inputs including DC voltage, thermocouples, RTDs, digital inputs, and current via shunt, providing a VFD display with bargraph and digital data readout. The recorder uses a Z‑fold chart about 20 m in length, is flush‑panel mounted, typically powered from 100–240 VAC (model dependent), and offers IP54 front‑panel protection, making it suitable for continuous data logging, compliance recording, and replacement of legacy chart recorders in process plants, power generation, manufacturing lines, and environmental monitoring. Note that this model is discontinued and has common replacements in Yokogawa’s µR10000 and µR20000 series (and the DX1000 paperless recorder).
