Ingcindezi: Amandla oketshezi olusebenza endaweni yeyunithi. Iyunithi yalo yokulinganisa esemthethweni yi-pascal, efanekiselwa yi-Pa.
Ingcindezi ephelele (P)A): Ukucindezela kulinganiswa ngokusekelwe ku-vacuum engenalutho (ukucindezela okungu-zero).
Ingcindezi yegeyiji (P)G): Ukucindezela kulinganiswa ngokusekelwe ekucindezelweni kwangempela komkhathi.
Ingcindezi evaliwe (P)S): Ingcindezi ilinganiswa ngokusekelwe kungcindezi ejwayelekile yomkhathi (101,325Pa).
Ukucindezela Okubi: Lapho inani lokucindezela kwegeji < ukucindezela okuphelele kwangempela. Kubizwa nangokuthi izinga le-vacuum.
Ukucindezela okuhlukile (P)D): Umehluko wokucindezela phakathi kwanoma yimaphi amaphuzu amabili.
Inzwa yokucindezela: Idivayisi izwa ingcindezi futhi iguqula isignali yokucindezela ibe isignali yokukhipha kagesi ngokwephethini ethile. Akukho circuit ye-amplifier ngaphakathi kwenzwa. Ukukhishwa kwesikali esigcwele ngokuvamile kuyiyunithi ye-milivolt. Inzwa inomthamo ophansi wokuthwala futhi ayikwazi ukuxhumanisa ikhompyutha ngqo.
Umthumeli wokucindezela: Umthumeli angaguqula isignali yokucindezela ibe isignali yokukhipha kagesi ejwayelekile enobudlelwano obuqhubekayo bokusebenza obuqondile. Izimpawu zokukhipha ezijwayelekile ezihlanganisiwe zivame ukuba ugesi oqondile: ① 4~20mA noma 1~5V; ② 0~10mA noma 0~10V. Ezinye izinhlobo zingaxhumana nekhompyutha ngqo.
Umthumeli wokucindezela = Inzwa yokucindezela + Isekethe ye-amplifier enikezelwe
Empeleni, abantu bavame ukungahlukanisi kahle phakathi kwamagama amadivayisi amabili. Omunye umuntu angase akhulume ngenzwa ebhekisela ku-transmitter enomphumela ongu-4~20mA.
