The document describes the features and characteristics of the CS3253-925 product.
The EDR‑N7A absolute pressure transmitter incorporates a semiconductor sensor and micro‑computer to provide high‑accuracy pressure measurement with a 4‑20 mA output. It is designed for process line absolute pressure monitoring and can be configured for various pressure ranges and communication options.
The device supports selectable pressure ranges (0.6‑27 kPa, 7‑133 kPa, 107‑800 kPa), operates from DC 11.4‑42.0 V, and offers HART communication, IP67 protection, and explosion‑proof versions (ExdoTCT4). Materials such as SUS316 diaphragm and SUS316L contact parts are specified for corrosion resistance. This manual is written in Japanese.
