ʻO ka PV660 piezoelectric velocity sensor kahi sensor vibration maʻamau i hoʻolālā ʻia no ka nānā ʻana a me ka pale ʻana i nā mīkini i nā wahi ʻoihana paʻakikī. ʻO ka PV660 kahi ʻoihana maʻamau IEPE (integrated electronics piezo electric) velocity sensor e koi ai i ka mana mau o kēia manawa a hāʻawi i kahi hōʻailona hoʻopuka vibration (AC voltage) ma kahi pae bias (DC voltage). Loaʻa ia me ka sensitivity o 4 mV/mm/s. Loaʻa ka PV660 ma ke ʻano he sensor wale nō (me kahi mea hoʻohui luna). Hiki i kēia ke hoʻohana ʻia i nā hui kelepona e hoʻopili i ka sensor i ka ʻōnaehana nānā, e pili ana i ka noi/kaiapuni. Loaʻa ka PV660 i nā mana maʻamau no ka hoʻohana ʻana i nā wahi maʻamau (ʻaʻole pilikia) wale nō.
