Miniature Tri-axial Piezoelectric accelerometer sensor in IEPE type
This series of micro accelerometer sensors is equipped with an accelerometer that 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.
1/4-28 four core socket output, capable of simultaneously measuring acceleration signals in the X, Y, and Z axes. It has a wide frequency response, small size, and light weight, making it suitable for vibration testing occasions such as modal analysis, motors and pumps, and precision machining.
