Abantu abaningi bavame ukwenza iphutha lokucindezela ama-transmitters kanye nezinzwa zokucindezela ezifanayo, ezimele izinzwa. Eqinisweni, ahluke kakhulu.
Ithuluzi lokulinganisa likagesi kuthuluzi lokulinganisa lokucindezela libizwa ngokuthi inzwa yengcindezi. Izinzwa zengcindezi ngokuvamile zakhiwa izinzwa ze-elastic kanye nezinzwa zokuxoxisana.
1. Umsebenzi we-Enstiastistic Element ukwenza isenzo sokulinganisa esikalwa endaweni ethile futhi usiguqule sibe yindawo yokufuduka noma ukuguqula, bese usiguqula sibe yisiginali kagesi esihlobene nengcindezi enobunzima noma i-strain gauge ebucayi. Kwesinye isikhathi imisebenzi yalezi zinto ezimbili ihlanganisiwe, njengenzwa eqinile yesifundazwe inzwa yePiezoresurive.
2. Ingcindezi iyinhlangano ebalulekile yenqubo yenqubo enqubweni yokusebenzisa kanye ne-aerospace, izindiza ze-Aviation kanye nasezimbonini zezokuvikela. Akudingeki kuphela ukumisa isilinganiso esisheshayo nesinamandla, kepha futhi kuboniswe ngokwedijithali bese uqopha imiphumela yokulinganisa. Ukushintshwa kwama-outomioreries amakhulu ama-oyela, izitshalo zamakhemikhali, izitshalo zamandla kanye nezitshalo zensimbi nezinsimbi nazo zidinga ukuhambisa ingcindezi namanye amapharamitha, ukugeleza kanye nokubona, zibe yikhompiyutha.
3. I-Pressure Sensor uhlobo lwenzwa ebaluleke kakhulu futhi yathuthukiswa ngokushesha okukhulu. Umkhuba wentuthuko we-Sensor Yengcebo ukuthuthukisa ukuthuthuka okuguqukayo kwejubane, ukunemba kanye nokwethenjwa, kanye ne-digitization ephelele kanye ne-intelligence. Izinzwa zengcindezi ezijwayelekile zifaka inzwa yengcindezi ye-capacial, inzwa yokucindezela yengcindezi, inzwa yengcindezi yehholo, inzwa yokucindezela kwe-fiber ye-Optical fiber, inzwa yengcindezi yengcindezi ye-resonant, njll.
Kunezinhlobo eziningi zama-transmitters. Ama-transmitter asetshenziswa ezinsizeni zokulawula izimboni ikakhulukazi afaka ama-transmitter okushisa, ingcindezi transmitter, ukuguqulwa kwe-transmitter, ukudluliselwa kwamanje, ukudlulisela iVoltage Transmitter nokunye.
1. I-transmitter ilingana ne-amplifier yesiginali. I-AC220V Transmitter esiyisebenzisayo ihlinzeka nge-DC10V Bridge Voltage ku-Sensor, bese ithola isiginali yempendulo, iyakhulisa kanye nokukhipha i-0V ~ 10v Voltage noma isiginali yamanje. Kukhona futhi ama-transmitters amancane e-DC24V, acishe abe makhulu njengezinzwa futhi kwesinye isikhathi afakwe ndawonye. Ngokuvamile, i-transmitter inikezela amandla enzwa futhi ikhulise isinali. I-sensor iqoqa kuphela amasiginali, njenge-strain gauge, eshintsha isiginali yokufuduka ibe isibonakaliso sokumelana. Vele, kukhona izinzwa ngaphandle kokuhlinzekwa kwamandla, njenge-thermocoumpules kanye ne-pezoelectric ceramics, ezivame ukusetshenziswa.
2. Sisebenzise izinhlobo ezahlukene zezinzwa zengcindezi, kepha umdluliseli awuzange ungene esikhundleni. Inzwa yengcindezi ithola isinali yokucindezela, ngokuvamile ibhekisa kumamitha ayinhloko. I-Transmitter yengcindezi ihlanganisa imitha eyinhloko kanye nemitha yesibili, futhi iguqula isibonakaliso esitholiwe ibe yi-Called 4-20, u-0-5v, isibonakaliso esicacile, futhi futhi "siba" isibonakaliso esijwayelekile bese "sikuthumela".
Inzwa yengcindezi ngokuvamile isho into ebucayi eguqula isiginali yengcindezi eshintshiwe ibe isibonakaliso esiguqukayo sokuphikisa noma isibonakaliso se-capacitance, njll. Into ye-Piezoresusive, njll. Into ye-Priezoresusive, njll. Into ye-Transmive ngokuvamile isho ingcindezi yengcindezelo ehlanganiswe nengcindezelo. Ngokuvamile, kungakhipha ngokuqondile isinali elijwayelekile le-voltage noma isinali yamanje ebudlelwaneni obuqondile nengcindezi yokuqoqwa okuqondile ngamathuluzi, i-PLC, ikhadi lokutholwa kanye neminye imishini.
