Piezoelectric accelerometer sensor made of 304 stainless steel, support 50-5g and 100-50g two ranges optional, output range ±5V, sensitivity ±5V/range, suitable for medium and high intensity vibration monitoring. Adopting M12*1 two-core output mode, output impedance <100Ω, bottom insulation impedance >10⁸Ω, to ensure clean and stable signal.
A piezo accelerometer is a sensor that uses the piezoelectric effect to convert mechanical vibrations into electrical signals. Its core component is a piezoelectric crystal or ceramic material, which generates an electrical charge signal proportional to the applied force when subjected to vibrations or impacts. These signals are converted by internal circuits and can output voltage, current, or digital signals, enabling real-time monitoring of vibration acceleration.
Piezo accelerometers are primarily suited for high-frequency, high-g-value vibration monitoring, while capacitive or MEMS accelerometers are more suitable for low-frequency, low-g-value dynamic or static detection. Piezoelectric sensors offer higher sensitivity, a broader frequency response (up to several thousand Hz or higher), and stronger environmental adaptability. However, they are typically unsuitable for static acceleration detection because they only respond to changing mechanical stress signals.
Common installation methods for piezoelectric accelerometer sensors include threaded mounting, magnetic attachment, adhesive bonding, and L-shaped mounting plate fixation. The following precautions should be observed during installation:
