Matsi: Ƙarfin ruwa mai aiki a yankin naúrar. Naúrar aunawa ta doka ita ce pascal, wadda Pa ke wakilta.
Matsi mai ƙarfi (P)A): An auna matsin lamba bisa ga cikakken injin (matsi sifili).
Matsi na ma'auni (P)G): An auna matsin lamba bisa ga ainihin matsin lamba na yanayi.
Matsi mai rufewa (P)S): An auna matsin lamba bisa ga matsin lamba na yanayi na yau da kullun (101,325Pa).
Matsi mara kyau: Lokacin da ƙimar ma'aunin matsin lamba < ainihin matsin lamba mai cikakken ƙarfi. Ana kuma kiransa da digirin injin.
Matsi mai bambanci (P)D): Bambancin matsin lamba tsakanin kowace maki biyu.
Na'urar firikwensin matsi: Na'urar tana jin matsin lamba kuma tana canza siginar matsi zuwa siginar fitarwa ta lantarki bisa ga wani tsari. Babu da'irar amplifier a cikin na'urar firikwensin. Fitar cikakken sikelin gabaɗaya na'urar milvolt ce. Na'urar firikwensin tana da ƙarancin ƙarfin ɗaukar kaya kuma ba za ta iya haɗa kwamfuta kai tsaye ba.
Mai watsa matsi: Mai watsawa zai iya canza siginar matsin lamba zuwa siginar fitarwa ta lantarki mai daidaito tare da ci gaba da alaƙar aiki mai layi. Siginar fitarwa ta daidaitattun daidaitattun yawanci suna kan wutar lantarki kai tsaye: ① 4~20mA ko 1~5V; ② 0~10mA ko 0~10V. Wasu nau'ikan na iya haɗawa da kwamfuta kai tsaye.
Mai watsa matsi = Na'urar firikwensin matsi + Da'irar amplifier da aka keɓe
A aikace, mutane ba sa bambanta sosai tsakanin sunayen na'urorin biyu. Wani zai iya magana game da firikwensin da aka ambata a zahiri yana nufin mai watsawa mai fitarwa 4 ~ 20mA.
