Machine monitoring vibration sensor AKP342

for machine condition monitoringfor fansfor wind turbine

Product description
AKP342 is a high-precision, low-noise triaxial vibration sensor designed for fan and wind-turbine monitoring. Units are calibrated and temperature-compensated across the operating range and are subjected to a minimum two-week stability test before shipment to ensure consistent long-term performance. The sensor integrates an FFT engine capable of measuring static (0 Hz) and low-frequency vibration (0.1–10 Hz), estimating vibration parameters and outputting 60-second RMS, maximum, minimum, peak-to-peak and first-order frequency/amplitude.
