Sensor maitiro

Sensor (sensor) inoreva mudziyo kana mudziyo unokwanisa kunzwa huwandu hwakatarwa hwemuviri uye wochishandura kuita chiratidzo chinogoneka chekuisa zvinoenderana nemumwe mutemo.Zvichitaurwa zviri nyore, sensor chinhu chinoshandura huwandu husiri hwemagetsi kuita huwandu hwemagetsi.

Sensor inowanzova nezvikamu zvitatu: chinhu chinonzwisisika, chinhu chekushandura uye chiyero chekuyera.

1), chinhu chinonzwa chinoreva chikamu chinogona kunzwa zvakananga (kana kupindura) chakayerwa, kureva kuti, chinhu chinonzwa chinoyerwa kuburikidza ne sensor chinoshandurwa kuita chisiri chemagetsi huwandu kana humwe huwandu hune hukama hwakasimba. neyakayerwa.

2) Chinhu chekushandura chinoshandura huwandu husiri hwemagetsi kuita parameter yemagetsi.

Static hunhu parameter index ye sensor

1. Sensitivity

Sensitivity inoreva chiyero chekubuda Y kuisa X ye sensor panzvimbo yakatsiga, kana chiyero chekuwedzera kwekubuda Y kusvika kukuwedzera kwekuisa X, iyo inoratidzirwa ne k as.

k=dY/dX

2. Chisarudzo

Iko kudiki shanduko iyo sensor inogona kuona mukati meyero yakatarwa inonzi resolution.

3. Chiyereso chekuyera uye kuyera chiyero

Mukati memuganho wemhosho inotenderwa, muganhu kubva pamuganhu wepasi kusvika kumuganhu wepamusoro weukoshi hwakayerwa hunonzi measuring range.

4. Linearity (kukanganisa kusiri kwemutsara)

Pasi pemamiriro ezvinhu akatarwa, chikamu chekutsauka kwepamusoro pakati pe sensor calibration curve uye yakarongedzerwa mutsara wakatwasuka uye iyo yakazara-chiyero chekubuda kukosha inonzi mutsara kana nonlinear kukanganisa.

5. Hysteresis

Hysteresis inoreva chiyero chekusawirirana pakati pezvakanaka sitiroko maitiro uye reverse sitiroko maitiro e sensor pasi pemamiriro akafanana ekushanda.

6. Kudzokorora

Kudzokororwa kunoreva kusaenderana kwechimiro chechimiro chinowanikwa nekuramba uchichinja huwandu hwekupinda munzira imwechete kwenguva dzakawanda muyero yese yekuyera pasi pemamiriro ekushanda akafanana.

⒎ Zero Drift uye tembiricha kudonha

Kana iyo sensor isina kupinza kana kupinza imwe kukosha, iyo muzana yekutsauka kwepamusoro kweiyo kukosha kwekuisa kubva kune yekutanga chiratidzo kukosha uye chiyero chakazara zero kudhiraivha nguva nenguva.Nekudaro, kune yega yega 1 ℃ kuwedzera kwekushisa, iyo muzana yekutsauka kwakanyanya kweiyo sensor inobuda kukosha kune yakazara chiyero inonzi tembiricha yekudonha.
