VMIACC_0562 Product Details
Product Overview
VMIACC_0562 is a high-precision three-axis acceleration sensor module launched by VMI(Vibration Monitoring International)or its partners,designed for industrial vibration monitoring,structural health analysis,rotating machinery fault diagnosis and other applications.The module integrates a three-axis(X/Y/Z)MEMS(micro-electromechanical system)accelerometer,supports wide-band vibration signal acquisition,and can be connected to a data acquisition system(DAQ),PLC or embedded controller through a digital interface(such as I2C,SPI)or analog output.Its compact design,high sensitivity and anti-interference ability make it suitable for harsh industrial environments.
Core Function
Three-axis synchronous measurement
Integrated X,Y,Z three-axis accelerometers can simultaneously measure vibration signals in three directions and comprehensively analyze equipment vibration characteristics(such as radial and axial vibrations).
Low cross-interference between axes(typical value<1%)ensures measurement independence.
Wideband response
Frequency range:0.5 Hz to 5 kHz(typical),covering low-frequency mechanical vibration(such as imbalance)to high-frequency fault characteristics(such as bearing defects).
Supports constant current(IEPE)or voltage output(some models),compatible with traditional vibration analyzers.
High accuracy and high sensitivity
Sensitivity:100 mV/g(typical, 1g acceleration),can detect small vibration changes.
Non-linearity:<0.1%FS(full scale),ensuring long-term measurement stability.
Resolution:up to 0.001g(depending on sampling rate and noise level),meeting the needs of precision diagnosis.
Anti-interference design
Protection level:IP67(dust and water proof),suitable for humid and dusty environments.
Temperature compensation:built-in temperature sensor,automatic correction of temperature drift(-40°C to+125°C operating range).
Electromagnetic compatibility(EMC):compliant with IEC 61000 standard,resistant to electromagnetic interference in industrial sites.
Flexible interface and power supply
Digital interface:supports I2C,SPI(some models),easy to integrate with embedded systems.
Analog output:0-5 V or 4-20 mA(optional),directly connected to PLC or DAQ devices.
Power supply:5-24 V DC wide voltage input,low power consumption design(typical value<10 mA).
