Description of DM9280 Digital Acceleration Vibration Sensor
DM9280 is an accelerometer that is highly suitable for power plants, paper mills, gas turbines, and other extensive industrial applications. Applied in some small applications, such as diesel engines, water pumps, generators, etc.
The DSP signal processor built into the sensor performs FFT (Fourier Transform) analysis on vibration data and calculates acceleration, velocity, and displacement values. Sensors can directly output vibration waveform data in both time and frequency domains.
Up to 64 vibration sensors can be connected to form a vibration measurement network, and a host (such as a PC computer) connected to this network can read vibration data, analyze and process the data.

3) Cable lead instructions:
The DM280 vibration sensor adopts an anti vibration stainless steel hose lead structure, and a 4-core (6-core) shielded cable provides power and RS485 communication for the sensor. The signal definition is distinguished by different cable colors. The following figure illustrates the sensor signal definition.
