Ukuqhathaniswa Kwezobuchwepheshe Kwamaseli Womthwalo

Ukuqhathaniswa kweIseli Lokulayisha I-Strain Gaugekanye ne-Digital Capacitive Senso Technology

Womabili amaseli omthwalo wegeji ye-capacitive kanye ne-strain gauge ancike ezintweni ezinwebekayo eziwohlokayo ekuphenduleni umthwalo ozokalwa.

Impahla yento enwebekayo ivamise ukuba yi-aluminium yamaseli okulayisha abiza kancane kanye nensimbi engagqwali kumaseli omthwalo wezinhlelo zokusebenza zezimboni ezibolayo.

Izinzwa ze-Capacitive strain gauge zikala ukuwohloka kwezinto ezinwebekayo ngazinye, futhi okukhiphayo kwezinzwa kuguqulwa isekethe ye-elekthronikhi ibe isignali emelela umthwalo.

I-capacitive sensor iyi-conductor ebekwe ebangeni elincane ukusuka ku-elastic element futhi ikala ukuwohloka ngaphandle kokuthintana nento enwebekayo, kuyilapho i-strain gage iyi-foil evikelayo evikelayo ehlanganiswe ngqo ne-elastic element ukuze ibonakale ngokuqondile Ekushaqekeni nasekulayisheni ngokweqile. , ezivame ukuhlangana nazo ekusetshenzisweni kwezimboni.

Ukuzwela
Ukwengeza, izinzwa ze-capacitive zizwela kakhulu, ngokushintsha kwe-10% ku-capacitance, kuyilapho ama-gauge e-foil strain ngokuvamile anoshintsho lwe-0.1% kuphela lokumelana. Njengoba izinzwa ze-capacitive zizwela kakhulu futhi ngenxa yalokho zidinga ukuwohloka okuphansi kakhulu kwe-elementi enwebekayo, ukucindezelwa kwesici sokunwebeka kweseli elithwala i-capacitive liphansi ngokuphindwe izikhathi ezi-5 kuya kweziyi-10 kunalelo leseli lomthwalo we-strain gauge.

Izintambo kanye nokuvala uphawu
Ushintsho oluphezulu lwamandla lusiza ekunikezeni isignali yokuphumayo yedijithali, lapho kumaseli omthwalo we-capacitive kuyisignali yesivinini esikhulu eveza ngokuqondile umthwalo ngo-g, kg, noma ama-Newtons. Intambo ye-coaxial ebiza kancane enesixhumi esivaliwe ngocingo olulodwa inika amandla iseli yokulayisha futhi idlulisele isignali yedijithali enesivinini esikhulu ibuyele ensimbini, engase ibekwe endaweni engamakhulu amamitha. Kuseli elijwayelekile lomthwalo we-analog strain gauge, ukunikezwa kwamandla kanye nesignali ye-analog yezinga eliphansi ngokuvamile kuqhutshwa emshinini ngentambo ebiza kakhulu engu-6 lapho isignali ye-analog iguqulelwa kudijithali. Kuseli lomthwalo wegeji ye-digital strain gauge, i-amplifier nokuguqulwa kwe-A/D kubekwa endlini, futhi amandla namasiginali edijithali ngokuvamile ahanjiswa kumathuluzi ngezintambo ezibiza kakhulu ezingu-6 noma ezingu-7.
