±3 g (ADXL335) chegarasida tezlik diapazoni
ADXL335 ±3 g gacha o'lchaganligi sababli, maksimal tebranish velocity sensor qayd eta oladigan qiymati chastotaga bog'liq. Quyidagi jadvalda tezlik chegarasi ko'rsatilgan — tezlanish ±3 g ga yetadigan daraja:
| Frequency | RPM | Vmaks (peak) | Vmaks (RMS) |
|---|---|---|---|
| 10 Hz | 600 | 468 mm/s | 331 mm/s |
| 25 Hz | 1500 | 187 mm/s | 132 mm/s |
| 50 Hz | 3000 | 93.7 mm/s | 66.2 mm/s |
| 100 Hz | 6000 | 46.8 mm/s | 33.1 mm/s |
| 200 Hz | 12000 | 23.4 mm/s | 16.6 mm/s |
| 500 Hz | 30000 | 9.4 mm/s | 6.6 mm/s |
| 1000 Hz | 60000 | 4.7 mm/s | 3.3 mm/s |
Calculation: Vpeak (mm/s) = 3 · 9810 / (2π·f) ≈ 4683 / f. RMS = peak / √2.
Bu sensor ±3 g chegarasiga yetgunga qadar bo'lgan maksimal tebranish tezligidir. Odatdagi balanslashtirish tezliklarida (1500–3000 ayl/daq) tezlik zaxirasi ISO 10816 bo'yicha istalgan chegaradan ancha yuqori; tezlanish cheklovi faqat 30 000 ayl/daq va undan yuqori yuqori tezlikli shpindellarda muhim ahamiyat kasb etadi.
