MJ-VR280 Digital vibration sensor

●  DSP digital signal processor       

●With RS485 digital interface

● With FFT frequency analysis

● Software can be upgraded

●Low cost, easy to install

● Relay outputOptional

    MJ-VR280 digital vibration sensor is a low cost vibration sensor, which with DSP digital signal processor and  RS485 digital interface. The mechanical vibration signal can be directly converted to digital waveform data, and through the RS485 interface of the sensor is transmitted to the computer. In order to make the sensor suitable for the wet environment, we select with stainless steel waterproof shell.

Sensor built-in DSP signal processor analyze vibration data through FFT( Fu Liye transformz), and calculated the acceleration, velocity and displacement. The sensor can directly output vibration wave data in time and frequency domain.

Up to 64 vibration sensors can be connected into a vibration measurement networkconnected to the host of this network ( like PC computer) read vibration data, analyze and process data.

MJ-VR280 configuration / monitoring software is a free vibration sensor testing software, vibration data collected through computer software by sensor

Cable signal definition

MJ-VR280 digital vibration sensor adopted antivibration stainless steel hose lead structure, power supply and RS485 communication through 4 core (6 core) shielded cable, The definition of signal is different from the cable color., the following diagram illustrates the definition of sensor signal.
