imikhiqizo

Inzwa ye-CA202 ifaka ingxenye yokulinganisa ye-shearmode ye-polycrystalline ene-insulation yekesi yangaphakathi kukesi le-austenitic stainlesssteel (indlu). I-CA202 ifakwe ikhebula elibalulekile elinomsindo ophansi elivikelwe ipayipi eliguquguqukayo lokuvikela insimbi engagqwali (leaktight) elishiselwe inzwa ukuze kukhiqizwe umhlangano ongavuzi ovaliwe. I-CA202 piezoelectric accelerometer iyatholakala ngezinguqulo ezihlukene ezindaweni ezihlukene zezimboni: Izinguqulo ze-Ex zokufakwa ezindaweni ezingase zibe neziqhumane (izindawo eziyingozi) nezinguqulo ezijwayelekile ezizosetshenziswa ezindaweni ezingenabungozi. I-CA202 piezoelectric accelerometer yakhelwe ukuqapha nokulinganiswa kokudlidliza kwemboni. Ngezinhlelo zokusebenza ezithile, xhumana nomele i-Meggitt yangakini.

Okujwayelekile

Izidingo zamandla okokufaka : Akukho

Ukudluliswa kwesignali : Isistimu yamaphini angu-2, ivalekile ekesini, ukuphuma kweshaji

Ukucutshungulwa kwesiginali : Isiguquli sokushaja (I-IPC70x yesiginali yesimondisi)

Isebenza (Ku-23°C ±5°C, 73°F ±9°F)

Ukuzwela (ku-120 Hz no-5 g, bona Ukulinganisa ekhasini 4) : 100 pC/g ±5%

Ibanga lokulinganisa elinamandla : 0.01 kuya ku-400 g ukuphakama

Umthamo wokulayisha ngokweqile (ama-spikes) : Kufika ku-500 g ukuphakama

Umugqa • 0.01 ukuya ku-20 g (ukuphakama) : ±1% • 20 ukuya ku-400 g (ukuphakama) : ±2%

Ukuzwela okuguquguqukayo : ≤3% Imvamisa ye-resonant : >22 kHz okuzisholo

Ukusabela kwemvamisa

• 0.5 kuya ku-6000 Hz : ±5% (imvamisa yokusika ephansi inqunywa isilungisi sesignali)

• Ukuchezuka okujwayelekile kokuthi 8 kHz : +10% Ukumelana nokufakwa kwangaphakathi : 109 Ω Ubuncane be-Capacitance (igama)

• Inzwa : 5000 pF pin to pin. 10 pF pin to case (umhlabathi).

• Ikhebula (imitha ngayinye yekhebula) : 105 pF/m ukuphinwa. 210 pF/m pin to case (umhlabathi). Ibanga lokushisa kwemvelo

• Ukusebenza okuqhubekayo : −55 kuya ku-+260°C (−67 kuya ku-+500°F) yenzwa. −55 kuya ku-+200°C (−67 kuya ku-+392°F) kukhebula ehlangene.

• Ukusinda kwesikhashana : −70 kuya ku-+280°C (−94 kuya ku-+536°F) kwenzwa. −62 kuya ku-+250°C (−80 kuya ku-+482°F) kukhebula ehlangene.

Iphutha lokuzwela izinga lokushisa (ngokuya ku-23°C, 73°F)

• −55 kuya +23°C (−67 kuya +73°F) : 0.25%/°C

• +23 kuya ku-260°C (−73 kuya +500°F) : 0.1%/°C Ukugqwala, umswakama

• Inzwa : Insimbi engagqwali ye-Austenitic (1.4441), eshiselwe nge-hermetically

• Ipayipi lokuvikela : Insimbi engagqwali engashisi (1.4541), ishiselwe nge-hermetically

Yazi: Inzwa kanye nepayipi elivikelayo eliguquguqukayo kushiselwe komunye nomunye nge-hermetically ukuze kwakheke ukuhlangana okuvuzayo okuvalwe kahle okungakwazi ukungena ku-100% umswakama ohlobene (RH), amanzi, isitimu, uwoyela, nomoya kasawoti wasolwandle, ngaphezu kokunye ukungcola okungaba khona njengothuli, ukhunta nesihlabathi. Ukuzwela kwe-base-strain : 0.15 x 10−3 g/µε ku-250 µε peak-peak-peak Ukusheshisa ukushaqeka : ≤1000 g ukuphakama (uhhafu wesine, ubude besikhathi esingu-1 ms)
