User manual for the JYB-G shipboard pressure and level transmitter, covering features, installation, wiring, safety, and troubleshooting.
The JYB-G shipboard pressure/level transmitter is designed for marine applications, measuring pressure and liquid level in various ship compartments. It complies with CCS certification and offers robust anti‑corrosion, anti‑overload, and anti‑condensation features.
The manual provides detailed instructions on installation (vertical mounting, use of pressure buffering for fast pressure changes), wiring (standard HART, 4‑20 mA or 0‑5 V output), safety measures for explosive environments, maintenance, and fault diagnosis. This manual is written in Chinese.
