This document introduces a product named PC, which has features such as WH, BU, BN, BK, etc., and is suitable for oil measurement. The product has 13 functional points and supports 4~20mA and O~10V input/output. For more detailed information, please visit www.ema-electronic.com.
This manual describes the working principle of the SMA G114 pressure transmitter, which converts pressure into a proportional voltage signal (0‑10 V) or current signal (4‑20 mA) via a Wheatstone bridge and signal conditioning circuit. It also explains how to configure output types (PNP/NPN) and alarm points through the interface circuit.
Key product features include simple structure, low power consumption, high measurement accuracy, robust solid‑state construction, and a digital calibration method. Technical data such as output ranges, power consumption, temperature limits, IP67 protection, and MTBF are listed, along with installation precautions and recommended operating conditions. This manual is written in Chinese.
