Murata’s PKGM-200D-R vibration sensor detects high-frequency vibrations as much as 11 kHz to help predictive upkeep in manufacturing tools. The system measures vibration acceleration alongside the Z-axis to detect irregular vibrations, which may point out early bearing put on and stop surprising tools stoppage.
For rotary bearings, engineers can make use of FFT evaluation on vibration information to pinpoint irregularities attributable to depleted grease or minor floor imperfections. By detecting these anomalies early on, FFT evaluation allows proactive intervention, probably averting impeding points earlier than they escalate.
Housed in a compact 5.0×5.0×3.5-mm surface-mount package deal, the PKGM-200D-R integrates a PZT piezoelectric ceramic component, driver circuit, and temperature sensor. Differential analog output reduces line noise. Specs for the sensor embody a detection vary of ±10.2 g minimal, a frequency band of 6 kHz to 11 kHz, and sensitivity of 118 mV/g typical.
The PKGM-200D-R vibration sensor requires a provide voltage of three.0 V to five.2 V, with present consumption of three.5 mA. It operates over a temperature vary of -20°C to +85°C. The system is now in mass manufacturing.
