Ukuxhumanisa izintambo zesikali samakhanda amaningi

Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

I-Multihead weigher iyithuluzi eliguqula amasignali edatha ekhwalithi abe amasignali kagesi. Luhlobo lwenzwa ezwela amandla. Ukusetshenziswa kwe-multihead weigher kuvame kakhulu, ikakhulukazi emishinini yokukala, okuyinhliziyo yemishini yokukala. Kulesi sigaba, kunezinhlobo eziningi ze-multihead weigher emakethe, njengohlobo lwe-resistor strain, uhlobo lwe-optical, uhlobo lokucindezela uwoyela, inzwa ye-capacitive, kanye nohlobo lwamandla kazibuthe. Uhlobo ngalunye lunezici zalo kanye nezinhlelo zalo. Kunezinhlobo ezimbili ze-multihead weigher: uhlelo lwezintambo ezine kanye nohlelo lwezintambo eziyisithupha. Njengamanje, uhlelo lwezintambo ezine luvame ukusetshenziswa emakethe.

Uhlelo olunezintambo ezine: EXC+, EXC-: Ipulaki yamandla, enikeza ukunikezwa kwamandla okulawulwa yi-DC kwe-inductor. Isisindo se-Cangzheng esinezinhloko eziningi i-EXC+ sibomvu ngokugqamile, i-EXC- ingwevu-mnyama. SIG+, SIG-: Umugqa wamandla, okungukuthi, umphumela womugqa wamandla yinzwa, ngokuvamile ukhipha isignali yedatha ye-mV, okuncike ku-voltage ejwayelekile yokusebenza kanye nokuzwela kwenzwa.

Isikali samakhanda amaningi i-Cangzheng i-SIG+ iluhlaza okotshani, i-SIG- imhlophe njengobisi. Uhlelo lwezintambo eziyisithupha: Ngaphezu kwezintambo ezine ezingenhla, kunezintambo ezimbili ezengeziwe kunesistimu yezintambo ezine: i-SEN+, imigqa yempendulo ye-SEN-:, okungukuthi, inzwa izophendula inani elithile le-voltage yokusebenza elitholwe kumitha yokulinganisa amakhanda amaningi. Ngaphezu kwalokho, izinzwa zezintambo ezine kanye nezintambo eziyisithupha ziyizintambo ezivikelwe: ISIKHUNGO Umehluko phakathi kwalezi ezimbili: isikali samakhanda amaningi esinezintambo ezine sisetshenziswa ezindaweni lapho isikali samakhanda amaningi kanye nesikali samakhanda amaningi ziseduze, kanye nokulahleka kwamandla okusebenza komzila ochaziwe Kuncane kakhulu; uhlelo lwezintambo eziyisithupha lusetshenziswa ezindaweni lapho kwenziwa khona ukulinganisa okunembile kwebanga elide, futhi ukulwa nokuphazamiseka kwalo kunamandla.

Ngokuvamile, isikali samakhanda amaningi sifanelekile kuma-sensor anezintambo ezine kanye nama-wire ayisithupha. Kodwa-ke, uma ufaka izintambo ku-sensor enezintambo ezine, sebenzisa umugqa wamandla ukuxhuma i-EXC+ kanye ne-SEN+, kanye ne-EXC- kanye ne-SEN- ekugcineni kwemitha yesikali samakhanda amaningi. Ukukhishwa kwesignali yedatha yesikali samakhanda amaningi kuyisignali yedatha ye-millivolt. Lesi siginali yedatha sibuthakathaka kakhulu. Ukukhishwa kwesikali esigcwele kwesikali samakhanda amaningi = ukuzwela kwe-voltage ejwayelekile yokusebenza *. Ngokuvamile, kumele kuhambisane ne-transmitter ehlakaniphile (i-amplifier) ​​​​noma ithuluzi lokubonisa ledijithali. Emsebenzini, indlela yokuxhuma ye-sensor imakwe ku-transmitter ehlakaniphile kanye nephaneli yethuluzi.
