Yuav ua li cas paub qhov zoo thiab qhov tsis zoo ntawm S-hom thermocouples

1. Txiav txim siab raws li qhov sib txawv voltage
Raws li lub hauv paus ntsiab lus ntawm thermocouples, yog tias qhov sib txawv ntawm ob lub thermocouple terminals yog qhov zoo, nws qhia tau hais tias qhov zoo electrode kub siab dua qhov kub tsis zoo electrode; Yog tias qhov sib txawv ntawm qhov tsis zoo, nws qhia tau hais tias qhov zoo electrode kub qis dua qhov tsis zoo electrode kub.

2. Kev txiav txim raws li cov khoom siv xim
Feem ntau, lub raj tiv thaiv ntawm qhov zoo thermocouple yog xim dawb, thaum lub raj tiv thaiv ntawm qhov tsis zoo thermocouple yog xim dub. Yog li ntawd, qhov polarity ntawm s-hom thermocouple tuaj yeem txiav txim siab raws li xim ntawm cov raj tiv thaiv.

3. Kev txiav txim raws li cov cim
Qee qhov S-hom thermocouples muaj cov cim ntawm lawv cov raj tiv thaiv, xws li lub cim "+" lossis lub cim liab uas qhia qhov zoo electrode, thaum lub cim "-" lossis lub cim xiav qhia qhov tsis zoo electrode. Los ntawm kev soj ntsuam cov cim no, qhov polarity ntawm s-hom thermocouple tuaj yeem txiav txim siab.

4. Siv lub tshuab digital multimeter los txiav txim
Teem lub digital multimeter rau voltage ntsuas hom, txuas cov probes mus rau ob qho kawg ntawm lub thermocouple, thiab saib xyuas tus nqi tso tawm. Yog hais tias tus nqi yog qhov zoo, nws qhia tau hais tias qhov zoo electrode kub siab tshaj qhov tsis zoo electrode kub; Yog tias tus nqi tsis zoo, nws qhia tau tias qhov zoo electrode kub qis dua qhov tsis zoo electrode kub.

5. Siv lub rooj hom clamp los txiav txim
Teem lub clamp hom meter rau qhov ntsuas kub hom, thiab clamp lub fixture mus rau ob qho kawg ntawm lub thermocouple los soj ntsuam cov txiaj ntsig tau tshwm sim ntawm lub ntsuas ntsuas clamp. Yog hais tias tus nqi yog qhov zoo, nws qhia tau hais tias qhov zoo electrode kub siab tshaj qhov tsis zoo electrode kub; Yog tias tus nqi tsis zoo, nws qhia tau tias qhov zoo electrode kub qis dua qhov tsis zoo electrode kub.

6. Nrog rau cov chaw tsim khoom rau kev txiav txim
Yog tias cov txheej txheem saum toj no tsis tuaj yeem txiav txim siab qhov polarity ntawm s-hom thermocouple, koj tuaj yeem sab laj nrog cov chaw tsim khoom ntawm cov thermocouple. Cov chaw tsim khoom yuav muab cov kev txiav txim kom raug raws li cov qauv tshwj xeeb thiab cov yam ntxwv ntawm cov khoom.

Los ntawm kev siv cov hau kev saum toj no, qhov polarity ntawm S-hom thermocouples tuaj yeem txiav txim siab kom raug thiab txhim khu kev ntsuas kub thaum siv.
