Makhalidwe a sensa

Sensa imatanthawuza chipangizo kapena chipangizo chomwe chimatha kuzindikira kuchuluka kwake kwakuthupi ndikuchisintha kukhala chizindikiro chomwe chingagwiritsidwe ntchito molingana ndi lamulo linalake. Mwachidule, sensa ndi chipangizo chomwe chimasintha kuchuluka kwa magetsi kukhala magetsi.

Sensa nthawi zambiri imakhala ndi magawo atatu: chinthu chodziwikiratu, chosinthira ndi dera loyezera.

1), chinthu chodziwika bwino chimatanthawuza gawo lomwe limatha kumva (kapena kuyankha) choyezera, ndiye kuti, chinthu chodziwika bwino chomwe chimayezedwa kudzera pa sensa chimasinthidwa kukhala chosakhala chamagetsi kapena kuchuluka kwina komwe kuli ndi ubale wotsimikizika. ndi miyeso.

2) Chinthu chosinthika chimasintha kuchuluka kwa magetsi kukhala gawo lamagetsi.

Static characteristic parameter index of sensor

1. Kumverera

Sensitivity imatanthawuza chiyerekezo cha kutulutsa kwa Y kupita ku kulowa X kwa sensa pamalo osasunthika, kapena chiwopsezo cha kuchuluka kwa kutulutsa Y mpaka kukulitsa kwa X, komwe kumawonetsedwa ndi k as.

k=dY/dX

2. Kusamvana

Kusintha kochepa komwe sensor imatha kuzindikira mkati mwa miyeso yodziwika imatchedwa kusamvana.

3. Muyezo wosiyanasiyana ndi mitundu yoyezera

Mkati mwa malire ovomerezeka olakwa, mulingo wochokera ku malire otsika mpaka kumtunda kwa mtengo woyezedwa umatchedwa muyeso woyezera.

4. Linearity (zolakwika zopanda mzere)

Pansi pamikhalidwe yodziwika, kuchuluka kwapang'onopang'ono kwapakatikati pakati pa sensa calibration curve ndi mzere wowongoka wowongoka komanso kuchuluka kwapang'onopang'ono kumatchedwa linearity kapena zolakwika zopanda mzere.

5. Hysteresis

Hysteresis imatanthawuza kuchuluka kwa kusagwirizana pakati pa mikhalidwe yabwino ya sitiroko ndi mawonekedwe a sitiroko am'mbuyo a sensa pansi pamikhalidwe yomweyi.

6. Kubwerezabwereza

Kubwerezabwereza kumatanthawuza kusagwirizana kwa mapindikidwe a khalidwe omwe amapezeka mwa kusintha kosalekeza kuchuluka kwa zolowetsa mu njira imodzi kwa nthawi zambiri muyeso yonse yoyezera pansi pa zochitika zomwezo zogwirira ntchito.

⒎ Zero Drift ndi kutentha kwapang'onopang'ono

Pamene sensa ilibe cholowera kapena kulowetsako ndi mtengo wina, kuchuluka kwapang'onopang'ono kwapang'onopang'ono kwa mtengo wolowera kuchokera pamtengo woyambira komanso sikelo yathunthu ndi zero drift pafupipafupi. Komabe, pakuwonjezeka kulikonse kwa kutentha kwa 1 ℃, kuchuluka kwapang'onopang'ono kwapang'onopang'ono kwa sensa yotulutsa mtengo mpaka sikelo yonse kumatchedwa kutentha kwa kutentha.
