Khopolo ea mefuta ea khatello, sensor le transmitter

Pressure: Matla a fluid medium a sebetsa sebakeng sa unit. Tekanyo ea eona ea molao ke pascal, e tšoantšetsoang ke Pa.

Khatello e felletseng (P_A): Khatello e lekantsoe ho ipapisitsoe le vacuum e felletseng (khatello ea zero).

Khatello ea sekhahla (P_G): Khatello e lekanngoa ho latela khatello ea sebele ea sepakapaka.

Khatello e tiisitsoeng (P_S): Khatello e lekantsoeng ho latela khatello e tloaelehileng ea sepakapaka (101,325Pa).

Khatello e mpe: Ha boleng ba khatello ea gauge <khatello ea sebele e feletseng. E boetse e bitsoa degree ea vacuum.

Khatello e fapaneng (P_D): Phapang ea khatello pakeng tsa lintlha leha e le life tse peli.

Sensor ea khatello: Sesebelisoa se utloa khatello ebe se fetola lets'oao la khatello ho ba lets'oao la tlhahiso ea motlakase ho latela mokhoa o itseng. Ha ho na potoloho ea amplifier ka har'a sensor. Sephetho se felletseng ka kakaretso ke yuniti ea milivolt. Sensor e na le matla a tlase a ho jara 'me ha e khone ho hokahanya komporo ka kotloloho.

Transmitter ea khatello: Transmitter e ka fetolela lets'oao la khatello hore e be lets'oao le tloaelehileng la tlhahiso ea motlakase ka kamano e tsoelang pele ea ts'ebetso. Matshwao a tlhahiso a kopaneng a tlwaelehileng hangata ke a hona jwale: ① 4~20mA kapa 1~5V; ② 0~10mA 0~10V. Mefuta e meng e ka hokahana le komporo ka kotloloho.

 

Mochine oa khatello = Sensor ea khatello + potoloho ea amplifier e inehetseng

 

Ha e le hantle, hangata batho ha ba etse phapang e tiileng pakeng tsa mabitso a lisebelisoa tse peli. Motho e mong a ka bua ka sensor eo leha ho le joalo e buang ka transmitter e nang le tlhahiso ea 4 ~ 20mA.
