Keqi SMF/WMF Wind Pressure Transmitter User Manual
The SMF/WMF wind pressure transmitters feature high sensitivity, high accuracy and strong overload resistance. They use an imported pressure chip and a highly integrated sensor and amplification circuit, housed in a die‑cast aluminum body with a painted surface. The sensor element forms a Wheatstone bridge whose resistance changes proportionally with applied pressure, producing a linear 4‑20 mA output.
The manual describes the device structure, adjustment method (zero‑point and span calibration using a standard power source and ammeter), and safety precautions such as avoiding direct mechanical stress on the membrane, proper torque on connections, and overload limits. Technical parameters such as measurement range, accuracy, supply voltage and environmental limits are also listed. This manual is written in Chinese.

Questions answered in SMF manuals
How do I adjust the zero and span of the SMF/WMF transmitter?
First, with the transmitter unpressurized, adjust the zero‑point resistor until the output current is 4 mA. Then apply full‑scale pressure and adjust the span resistor until the output reaches 20 mA. Repeat the steps two or three times until the signal is stable, and finally tighten the protection cover.
