Ua hauj lwm txoj cai ntawm kev siv zog thermocouple

Ua li cas tho cov thermocouple ua hauj lwm? Nyob rau hauv cov ntaub ntawv ntawm

1, daim ntawv thov ntawm lub zog thermocouple

Feem ntau thiab pom cov twj paj nruag, cov ntaubntawv povthawj siv, electronic computing thiab lwm yam kev txhawb nqa kev siv. Kev ntsuas ncaj qha ntawm cov kua, cov pa hluavtaws thiab cov kis kub thiab cov khoom kub deg hauv qhov ntau ntawm 0 ° C txog 1300 ° C ntawm cov khoom tawg xws li cov zaubmov uas muaj nyob rau hauv qhov chaw ua haujlwm.

2, tus yam ntxwv ntawm armored thermocouple

· Muaj ntau hom tawg, daim ntawv pov thawj tawg yog qhov zoo;

· Spring-type temperature sensing element, kev ua haujlwm zoo los tiv thaiv kev vibration;

· Cov ntsuas kub ntau;

· High mechanical zog, kev ua haujlwm zoo;

3, thermocouple armored ua haujlwm

Kev siv thaij thaus npau yog siv cov qauv kev sib txawv ntawm qhov sib tsoo tawg, tsim nrog lub zog ntawm lub thawv ntuag thiab lwm yam khoom, yuav ua rau txhua lub txim, kab mob thiab qhov chaw kub hnyiab raug ntim rau hauv lub qhov rooj kab noj hniav, thaum muaj kab noj hniav, Los ntawm qhov sib txeeb ntawm qhov sib txawv ntawm lub nplaim thiab cua txias, thiaj li hais tias tom qab tawg ntawm nplaim taws thiab kub tsis tuaj yeem tawm sab nraud cov kab noj hniav, thiaj li coj tus flameproof.

4, lub ntsiab kev tsis ntawm kev siv zog thermocouple

Cov qauv siv khoom tsim: IEC584, EC1515, GB / T16839-1997, JB / T5518-91, GB3836

5, muaj zog thermocouple ntawm chav tsev kub Kub yeem tawm ua haujlwm:

Cov thermocouple ntawm kub nruab nrab ntawm 20 ± 15 ° C, sib txheeb ze ntawm tsis tshaj li ntawm 80%, qhov kev ntsuas ntawm 500 ± 50V (DC) ntawm cov electrode thiab cov rwb thaiv tsev ntawm cov khoob> 1000Ω.m

Kev siv thermocouple compensation tel yuav tsum xyuam xim rau cov qauv kev sib tw, lub polarity tsis tuaj yeem yuam kev, nyiaj xaim thiab thermocouple kev txuas sab ntawm qhov kub tsis tshaj 100 ℃.
