Tunanin nau'ikan matsin lamba, firikwensin da mai watsawa

Matsi: Ƙarfin matsakaicin ruwa mai aiki akan yanki naúrar.Naúrar ma'auni na doka ita ce pascal, alama ce ta Pa.

Cikakken matsi (P_A: Matsi da aka auna bisa cikakken matsa lamba (sifili).

Ma'aunin ma'auni (P_G): Matsi da aka auna bisa ainihin matsi na yanayi.

Rufe matsi (P_S): Matsi da aka auna bisa daidaitaccen yanayin yanayi (101,325Pa).

Matsin mara kyau: Lokacin da ƙimar ma'aunin ma'auni

Matsa lamba daban-daban (P_D): Bambancin matsin lamba tsakanin kowane maki biyu.

Na'urar firikwensin matsin lamba: Na'urar tana jin matsa lamba kuma tana canza siginar matsa lamba zuwa siginar fitarwar lantarki bisa ga takamaiman tsari.Babu da'irar amplifier a cikin firikwensin.Cikakken sikelin fitarwa shine gabaɗaya naúrar milivolt.Na'urar firikwensin yana da ƙarancin ɗaukar nauyi kuma ba zai iya mu'amala da kwamfuta kai tsaye ba.

Mai watsa matsi: Mai watsawa na iya juyar da siginar matsa lamba zuwa daidaitaccen siginar fitarwar lantarki tare da ci gaba da alaƙar aikin layi.Haɗin kai daidaitattun sigina na fitarwa yawanci yawanci kai tsaye: ① 4 ~ 20mA ko 1 ~ 5V;0 ~ 10mA 0 ~ 10V.Wasu nau'ikan na iya yin mu'amala da kwamfuta kai tsaye.

 

Mai watsa matsi = firikwensin matsin lamba + Sadadden da'irar amplifier

 

A aikace, sau da yawa mutane ba sa bambancewa tsakanin sunayen na'urorin biyu.Wani na iya yin magana game da firikwensin wanda haƙiƙa yana nufin mai watsawa tare da fitowar 4 ~ 20mA.
