Inzwa yokucindezela kawoyela yemishini yokwakha 12617592532

Izici ze-Sensor

Inzwa isho idivaysi noma idivaysi engabona ubuningi obucacisiwe ngokomzimba bese uyiguqula ibe isibonakaliso sokufaka esisebenzisekayo ngokuya ngomthetho othile. Kalula nje, inzwa iyithuluzi eliguqula inani elingewona amagesi ngobungako bakamagesi.

I-sensor imvamisa iqukethe izingxenye ezintathu: into ebucayi, into yokuguqula kanye nomjikelezo wokulinganisa.

1), into ebucayi ibhekisa engxenyeni engazizwa ngokuqondile (noma iphendule), okungukuthi, into ebucayi elikalwa nge-sensor iguqulwa ibe yinani elingelona kagesi noma elinye inani elinobudlelwano obucacile nangokulinganiswa.

2) Into yokuguqulwa iguqula inani elingelona likagesi libe yipharamitha kagesi.

Inkomba yepharamitha ye-static yohlamvu lwe-sensor

1. Ukuzwela

Ukuzwela kubhekisele kwisilinganiso sokukhipha y Ukufaka u-X we-sensor e-steady State, noma isilinganiso sokukhuphuka kokukhipha y ukwengeza kokufaka x, okuvezwa yi-K njengoba

k = dy / dx

2. Isinqumo

Ushintsho oluncane lwenzwa lungabona ngaphakathi kwebanga lokulinganisa elicacisiwe libizwa ngokuthi ukulungiswa.

3. Ukulinganisa ibanga kanye nobubanzi bokulinganisa

Ngaphakathi komkhawulo wephutha elivumelekile, ibanga ukusuka komkhawulo ophansi kuya kumkhawulo ophezulu wenani elinganisiwe libizwa ngokuthi yibanga lokulinganisa.

4. I-Lineartity (Iphutha le-Nonlinear)

Ngaphansi kwemibandela ebekiwe, iphesenti lokuphambuka okuphezulu phakathi kwejika lokulinganisa inzwa kanye ne-line eliqondile elihlanganisiwe kanye nenani lokukhipha okugcwele libizwa ngokuthi i-lineartity noma iphutha le-nonlineaar.

I-5. Hysteresis

I-Hysteresis ibhekisela ezingeni lokungahambisani phakathi kwezimpawu ezinhle zohlangothi kanye nezici zenhlangothi ezihle kakhulu zenzwa ngaphansi kwezimo ezifanayo zokusebenza.

6. Ukuphindaphinda

Ukuphindaphinda kubhekiselwa ekungeneni kwejika lesimo esitholwe ngokushintsha ngokuqhubekayo inani lokufaka endaweni efanayo izikhathi eziningi ezifanayo ngaphansi kwezimo ezifanayo zokulinganisa.

⒎ Zero Drift kanye Temperature Drift

Lapho inzwa ingenakho okufakwayo noma okufakwayo kungenye inani, iphesenti lokuphambuka okuphezulu kwenani lokufaka kusuka kunani lokukhonjiswa kwangempela kanye nesilinganiso esigcwele kungu-zero drift ngezikhathi ezithile. Kodwa-ke, kuwo wonke amazinga okushisa angu-1
