Bently Nevada 330500-07-04 Ko te Velomitor piezoelectric velocity sensor he mea hanga e Bently Nevada Corporation ka hangaia hei ine i te wiri tino (e pa ana ki te waahi waatea) o te whare whai, whare, hanganga ranei.

Ko te 330500 he piezoelectric accelerometer motuhake he hoahoa totika me te hikohiko kua whakauruhia.

Ma te hikohiko totika me te kore o nga waahanga neke, kaore e pa ki te paheketanga o te miihini me te kakahu, ka taea te whakanoho poutū, whakapae, ki tetahi atu koki ranei.
Āhuatanga:

1. Te Hiko Hiko: Ma te kaha o te 3.94mV/mm/s (100 mV/in/s) me te hapa i roto i te ±5%, ka taea e ia te huri tika i nga tohu tere wiri ki nga tohu hiko.
2. Te whakautu auau: I roto i te awhe o te 4.5 Hz ki te 5 kHz (270 cpm ki te 300 kcpm), ko te hapa whakautu he ± 3.0 dB; i te awhe auau o te 6.0 Hz ki te 2.5 kHz (360 cpm ki te 150 kcpm), ko te hapa whakautu he ±0.9 dB, ka taea te urutau ki nga inenga wiri o nga rerenga rereke.
3. Te tairongo pāmahana: I roto i te awhe pāmahana whakahaere, ko te uara angamaheni o te tairongo pāmahana kei waenganui i - 14% me + 7.5%, e tohu ana ka pangia e nga huringa pāmahana i roto i tetahi awhe ka taea te whakahaere.
