Technology
Single Axis Vibration Sensor
Single Axis Vibration Sensor
Product Introduction
The ICP/IEPE piezoelectric accelerometer comes with an internal charge amplifier, where power supply and signal output share a single cable (commonly known as a two-wire system, i.e., coaxial cable providing a constant current power supply of 2-10mA to the sensor, and the output signal is also transmitted through this coaxial cable).
The components utilize stable piezoelectric ceramic crystal materials. The piezoelectric ceramic sensor elements exhibit excellent long-term stability, ensuring prolonged, repeatable, and accurate measurements.
Additionally, the shear-type element design features low lateral sensitivity, insensitivity to base deformation and thermal transients, reducing interference, providing reliability, and simplifying testing methods. ICP/IEPE accelerometers support long-distance signal transmission.
Product Parameters
The product parameters meet the international standards, ensuring excellent performance.
