This document describes the features and characteristics of products from the brand EMA Electronic, including PC, WH, BU, BN, BK models, their technical specifications, and the corresponding input/output signal types and voltage ranges.
The manual describes the operating principle of the G114 pressure transmitter, where pressure applied to a diaphragm changes resistance in a Wheatstone bridge, producing a voltage proportional to pressure that is converted to standard 0‑10 V or 4‑20 mA signals. It also details the device's simple structure, low power consumption, high measurement accuracy, and robust solid‑state construction.
Key sections cover product features, functional specifications such as output ranges, voltage drop, power consumption, temperature limits, pressure ranges, IP67 protection, and installation guidelines including wiring for PNP/NPN outputs and recommended mounting orientation. This manual is written in Chinese.
