Small Single Axis Voltage Sensor Output Acceleration Sensor Piezotronic Miniature IEPE Accelerometer Micro Sensors
This series of micro acceleration sensors is equipped with an accelerometer with a built-in circuit, which converts high impedance charge signals into low impedance voltage signals, and uses coaxial cables to simultaneously perform constant current source excitation input and signal output.
Wide frequency response, small size, light weight, suitable for applications such as structural testing, fatigue testing, environmental testing, drop testing, component calibration, high-frequency applications, etc.
