I-sensor yokucindezela uwoyela 161-1705-07 ye-Cat Excavator E330C

Umgomo Wokusebenza

I-Sensor yakhelwe ngomgomo wokunwetshwa kwensimbi

inzwa yokushisa

inzwa yokushisa

I-Metal izokhiqiza ukunwetshwa okuhambisanayo ngemuva kokushintsha kwezinga lokushisa kwezemvelo, ngakho inzwa ingaguqula isiginali yalokhu kusabela ngezindlela ezihlukile. isithupha

Inzwa ye-bimetallic chip

Ishidi le-Bimetallic liqukethe izingcezu ezimbili zensimbi ezinama-coefficients ahlukile anamathele ndawonye. Ngoshintsho lwamazinga okushisa, izinga lokukhulisa lezinto ezibonakalayo a liphakeme kunaleso elinye insimbi, elibangela ishidi lensimbi ligobe. I-curvature ye-bend ingaguqulwa ibe isinali yokuphuma.

I-Bimetal Rod ne-Metal Tube Sensor

Ngokunyuka kwamazinga okushisa, ubude be-tube yensimbi (izinto ezibonakalayo a) kuyanda, kepha ubude benduku yensimbi engaxhunyiwe (i-metal b) ayitholi, ngakho-ke ukwandiswa okuqondile kweshubhu lensimbi kungatholwa ngenxa yokushintshwa kwesikhundla. Futhi, lokhu kwandiswa okuqondile kungaguqulwa kube yisiginali yokuphuma.

Inzwa yokuthola ijika le-defformation curve loketshezi negesi

Lapho izinga lokushisa lishintsha, umthamo wevolumu negesi nakho kuzoshintsha ngokufanele.

Izinhlobo ezahlukahlukene zezakhiwo zingaguqula lolu shintsho lokunwebeka lube lushintsho lwesikhundla, ngaleyo ndlela lukhiqize indawo yokushintsha isikhundla (i-Potentiometator, ukuphambuka okubangelwayo, okuxakayo, njll.).

Ukumelana nokuzwela

Ngoshintsho lokushisa, inani lokumelana lensimbi liyashintsha.

Ngezinsimbi ezihlukile, ukuguqulwa kwenani lokumelana kwehlukile ngaso sonke isikhathi lapho izinguquko zokushisa zishintsha nge-degree eyodwa, futhi inani lokumelana lingasetshenziswa ngqo njengesiginali yokuphuma.

Kunezinhlobo ezimbili zezinguquko zokumelana.

Coueffleeflication yokushisa okuhle

Ukuvuka kokushisa = ukukhuphuka kokumelana

Ukwehla kokushisa = ukwehla kokumelana.

I-coeffient engalungile yokushisa

Ukushisa kukhuphuka = ​​ukumelana kuyancipha.

Izinga lokushisa lincipha = ukumelana kuyanda.

I-Thermocouple Sensing

I-thermocouple iqukethe izintambo ezimbili zensimbi zezinto ezihlukile, ezifakwe ndawonye emikhawulweni. Ngokukala okushisa okukhona kwengxenye engashintshiwe, izinga lokushisa lendawo yokushisa lingaziwa ngokunembile. Ngoba kumele ibe nabaqhubi ababili bezinto ezihlukile, ibizwa ngokuthi i-thermocouple. Ama-thermocoumpules enziwe ngezinto ezahlukahlukene asetshenziswa kumabanga okushisa ahlukene, futhi ukuzwela kwawo nakho kuhlukile. Ukuzwela kwe-thermocouple kubhekisa ekushintsheni komehluko ongaba khona lapho amazinga okushisa okushisa ashintsha ngo-1 ℃. Kuma-thermocouples amaningi asekelwa yizinto zensimbi, leli nani lingama-microvolts acishe abe ngu-5 ~ 40.

Ngoba ukuzwela kwe-thermocouple lokushisa sensor akuhlangene ngalutho nobukhulu bezinto ezibonakalayo, nakho kungenziwa ngezinto ezinhle kakhulu. Futhi, ngenxa yokuhlehlisa okuhle kwezinto zensimbi ezisetshenziselwa ukwenza i-thermocouple, le nto encane yokulinganisa izinga lokushisa inesivinini esikhulu kakhulu sokuphendula futhi ingalinganisa inqubo yokushintsha okusheshayo.
