Hana ʻia ʻo Bently Nevada 330500-07-04 Velomitor piezoelectric velocity sensor e Bently Nevada Corporation a ua hoʻolālā ʻia e ana i ka haʻalulu piha (e pili ana i kahi kaʻawale) o kahi hale, hale a hale paha.

ʻO ka 330500 kahi piezoelectric accelerometer kūikawā kahi hoʻolālā paʻa me nā mea uila i hoʻopili ʻia.

Me nā lako uila paʻa a ʻaʻohe ʻāpana neʻe, ʻaʻole hiki ke hoʻohaʻahaʻa ʻia a me ka ʻaʻahu ʻana, a hiki ke kau ʻia ma ke kū pololei, horizontally a i ʻole ma kekahi kihi ʻē aʻe.
Nā hiʻohiʻona:

1. ʻIke uila: Me ka sensitivity o 3.94mV/mm/s (100 mV/in/s) a me kahi hewa i loko o ± 5%, hiki iā ia ke hoʻololi pololei i nā hōʻailona velocity vibration i nā hōʻailona uila.
2. Ka pane pinepine: Ma ke alapine o 4.5 Hz a 5 kHz (270 cpm a 300 kcpm), ʻo ± 3.0 dB ka hewa pane; ma ke alapine alapine o 6.0 Hz a 2.5 kHz (360 cpm a 150 kcpm), ʻo ka hewa pane he ± 0.9 dB, hiki ke hoʻololi i nā ana vibration o nā alapine like ʻole.
3. ʻIke wela: Ma ke ʻano wela o ka hana, ʻo ka waiwai maʻamau o ka ʻike wela ma waena o - 14% a me + 7.5%, e hōʻike ana i ka hopena o ka hoʻololi ʻana o ka mahana i loko o kahi ākea hiki ke mālama ʻia.
