III. Ƙa'idar Aiki Mai Zurfafa: Tasirin Piezoelectric da Fasahar IEPE

Babban ka'idar aiki na 330400 accelerometer ya dogara ne akan Tasirin Piezoelectric kuma ya haɗa fasahar Integrated Electronics Piezo-Electric (IEPE), wani balagagge kuma abin dogara ƙira.

1. Tasirin Piezoelectric: Canza Makamashin Injini zuwa Makamashin Lantarki

• Mahimmin Sensing Element: Zuciyar firikwensin shine kristal piezoelectric (yawanci ma'adini ko yumburan piezoelectric na musamman). Wannan kayan yana da keɓaɓɓen kadarorin jiki: lokacin da aka fuskanci damuwa na inji (misali, matsawa ko tashin hankali), yana haifar da cajin wutar lantarki na ciki daidai da ƙarfin da ake amfani da shi. Ana kiran wannan da Tasirin Piezoelectric Kai tsaye.

• Seismic Mass and Force Application: A cikin firikwensin, an ɗora ma'aunin girgizar ƙasa akan ma'aunin piezoelectric. Lokacin da tushen firikwensin ya yi rawar jiki tare da cak ɗin na'ura, bisa ga Newton's Law na Biyu (F=ma), yawan girgizar ƙasa yana haifar da ƙarfin da bai dace ba daidai da saurin girgiza. Ana ci gaba da yin amfani da wannan ƙarfin akan kristal piezoelectric.

• Ƙarfafa Ƙarfafawa: Tun da ƙarfin (F) akan kristal piezoelectric daidai yake da haɓakawa (a) (F = m·a, tare da taro m kasancewa akai-akai), cajin lantarki (Q) wanda kristal piezoelectric ya haifar kuma yana daidai da ma'auni acceleration (a). Don haka, bayanin hanzarin girgizar injin yana juyar da shi zuwa bambancin cajin lantarki.

2. Gina-ginen Microelectronics da Tsarin IEPE
   Siginar cajin piezoelectric mai rauni yana da rauni sosai kuma yana da babban cikas, yana mai da shi saurin kamuwa da hayaniyar kebul da wahalar watsawa a nesa mai nisa. 330400 tana amfani da fasahar IEPE (kuma aka sani da ICP®) don magance wannan matsalar.

• Ƙara Siginar Sigina da Juya Hali: Ƙarƙamar ƙaramar ƙarar caji ko da'irar mai canzawa tana haɗawa a cikin firikwensin. Wannan da'irar tana juyar da siginar caji mai ƙarfi daga kristal piezoelectric zuwa siginar ƙarancin ƙarfin ƙarfi. Wannan shine asalin ji na firikwensin (100 mV/g) - ga kowane 1g na shigarwar hanzari, kewayawa yana fitar da siginar millivolt 100.

• Samar da Wutar Lantarki na Zamani & Watsawa Sigina: Babban fasalin tsarin IEPE shine tsarin wayoyi biyu. Ana amfani da kebul iri ɗaya duka don samar da wutar DC zuwa na'urorin lantarki na ciki na firikwensin (yawanci -24 Vdc, kamar yadda 330400 ya buƙata) da kuma fitar da siginar girgiza AC. Tsarin sa ido ko mai kusanci yana ba da madaidaicin halin yanzu zuwa firikwensin (na 330400, halin yanzu son rai shine 2 mA mara kyau). Na'urorin lantarki na ciki suna daidaita wannan halin yanzu, suna haɓaka siginar wutar lantarki akan wutar lantarki ta DC. A ƙarshen karɓar, tsarin kulawa yana amfani da capacitor mai haɗawa don toshe bangaren DC, yana fitar da siginar girgiza AC mai tsabta.

• Bias Voltage: Under static (zero acceleration) conditions, the sensor outputs a stable DC voltage, known as the Bias Voltage (for the 330400, it is -8.5 ± 0.5 Vdc). Wannan ƙarfin lantarki shine wurin tunani da ake buƙata don kewayawa na ciki yayi aiki daidai, kuma dole ne tsarin kulawa ya samar da hanyar DC don shi.

3. Amsa Mita-Tsarki da Karawa

• Ƙwaƙwalwar Mitar Aiki: Ƙayyadaddun 10 Hz zuwa 15 kHz (± 3 dB) shine kewayon mitar da 330400 zai iya yin ma'auni daidai. A ƙasa da 10 Hz, amsawar firikwensin ya tashi; sama da 15 kHz, amsa yana tashi da ƙarfi yayin da yake gabatowa ta mitar resonant.

• Mitar Resonant Mai Haɗawa: Kowane hanzarin mita yana da mitar resonant na halitta. Mitar resonant na 330400 da aka ɗora ya fi 30 kHz. Wannan siffa ce mai kyawawa saboda tana da nisa sama da rukunin aikin sa (15 kHz), yana tabbatar da amsa mai faɗi mai faɗi da amsa lokaci mai layi a cikin rukunin aiki, yana guje wa karkatar da sigina ta hanyar resonance. Ana sarrafa kololuwar resonant zuwa iyakar 20 dB.

4. Rarraba Muhalli da Tsangwama Tsare Tsare Tsare

• Matsakaicin Zazzabi: Kaddarorin kayan aikin lantarki da kayan piezoelectric suna canzawa tare da zafin jiki. An ƙera 330400 don ci gaba da ingantaccen aiki akan kewayon zafin jiki mai faɗi, tare da yanayin zafin yanayi na -11% zuwa + 3% sama da kewayon zafin aikinsa.

• Sensitivity mai jujjuyawa: Har ila yau, firikwensin yana da ɗan hankali ga rawar jiki daidai da babban axis. Hannun juzu'i na 330400 bai kai kashi 5% ba, adadi mai kyau yana nuna ƙarancin hankali ga girgizawa a cikin hanyoyin da ba a aunawa ba, yana tabbatar da daidaiton bayanai.

• Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwaƙwalwa na Ƙarya na Ƙarya na Ƙarya ) na Ƙarya na Ƙarya na Ƙarya. Domin 330400 raka'a tare da serial lambobin gabace ta 'G' (ciki har da duk sabon model), da tushe iri ji na ƙwarai rage zuwa 0.0005 g/µε (lokacin amfani da kawota API hawa tushe). Wannan yana da mahimmanci a aikace-aikace tare da manyan gradients na thermal ko akan sifofi masu saurin lalacewa.

• Immunity EMI: Harshen ƙarfe da kebul mai kariya suna ba da kariya ta lantarki mai kyau. Lallacewar filin maganadisa bai wuce 225 mg/gauss ba, ma'ana yana iya aiki da ƙarfi ko da a cikin yanayin filin maganadisu mai ƙarfi.

• Hatimin Muhalli: Case ɗin firikwensin an yi shi da bakin karfe 316L kuma an rufe shi ta hanyar hermetically, yana samun ƙimar IP68 (mai ƙura da hana ruwa), yana ba shi damar jure yanayin zafi na 100% da matsananciyar yanayin masana'antu.
