The Nanpu integrated temperature transmitter converts signals from thermocouples, RTDs, resistance and voltage sensors into a standardized 4‑20 mA current loop. It supports a two‑wire system and offers configurable measurement ranges, high accuracy, and explosion‑proof certification for use in industrial environments such as power, metallurgy, petrochemical, and food processing.
The device operates from a 12‑30 V DC supply (rated 24 V) and includes features like fault monitoring, electromagnetic compatibility, and optional PC configuration via PROFIBUS‑PA or HART protocols. Various mounting options and waterproof connection boxes are provided for flexible installation.
