This manual describes the operating principle of the SMA PB pressure transmitter, which converts pressure into a proportional voltage or current signal. It explains the sensor's bridge circuit, the digital calibration method, and the selectable output modes.
Key features include low power consumption, high measurement accuracy, robust construction with IP67 protection, and flexible PNP/NPN output configuration. The document also provides wiring diagrams, physical dimensions, and installation precautions for both 0‑10 V and 4‑20 mA output types. This manual is written in Chinese.
