Cov Hom Khoom Siv Hluav Taws Xob Hluav Taws Xob

Cov kev ntsuas kub kom sib xyaw yog feem ntau muaj kev soj ntsuam kub (thermocouple lossis thermal resistor sensor) thiab ob-hlau tau ruaj khov chav tsev. Cov kev soj ntsuam kub yog ncaj qha ntsia hauv lub thawv hlws ris uas siv cov qauv-xeev module los ua cov khoom sib xyaw. Cov kev sib xyaw ua ke hloov hluav taws xob feem ntau muab faib ua ob hom: thermal resistor thiab thermocouple.

Lub thermal resistor kub xovxwm xa tawm ntawm ib chav tsev, chav sib hloov, rov qab tiv thaiv kev sib txuas, thim rov qab tiv thaiv tam sim no, thiab chav hloov pauv. Tom qab ntsuas qhov ntsuas kub ntsuas hluav taws xob muab teeb liab yog hloov dua siab tshiab ntawm kev ntsuas qhov kub thiab tsis muaj kev cuam tshuam nrog qhov ntsuas kub tam sim no tom qab kuv hloov mus rau hluav taws xob.

Lub thermocouple qhov hloov hluav taws xob feem ntau muaj cov ntaub ntawv them nqi, kev kho mob txias, hloov dua tshiab, thim kev sib txuas ntawm, thiab lwm cov chaw sib txuas. Nws yog kom ua kom nrov dua lub thermoelectric peev xwm tsim los ntawm thermocouplle kev them nyiaj thiab kub thiab txias thiab kub thiab hloov nws mus rau 4 ~ 20ma Tam sim no cov khoom xa tawm. Txhawm rau kom tsis txhob muaj xwm txheej los ntawm kev ntsuas kub tsis ua haujlwm vim yog thermocouple ntsuas, lub tshuab xa hluav taws xob, lub nkoj hluav taws xob tiv thaiv hluav taws xob. Thaum tus xov thermocouple tawg lossis qhov txuas tsis zoo, lub transmitter yuav tso tawm cov nqi siab tshaj plaws (28ma) txiav tawm lub zog hluav taws xob.

Cov kev sib xyaw ua ke xa tawm tau qhov zoo ntawm cov qauv yooj yim, kev tiv thaiv kev tiv thaiv loj, cov khoom pov thawj loj, rov qab cov kev sib txuas, thiab kev ua haujlwm tsis yooj yim.

Cov zis ntawm cov kev sib xyaw ua ke xa tawm yog kev sib koom ua ke 4 ~ 20ma teeb liab; Nws tuaj yeem siv nrog kev sib txuas nrog cov microcomputer system lossis lwm yam twj paj nruag. Cov neeg siv kuj tuaj yeem thov kom nws mus rau hauv kev tawg-ntawv pov thawj lossis ntsuas hluav taws kub ntsuas.
