Thermocouples, Kuj kub hnyiab, NTC tus cua nab

Kub Sensors yog siv los nres ntsuas kub. Txawm hais tias lawv muaj ntau, hauv kev siv tswv yim, thermocouples, ua thermometers, thiab NTC cov cua nab kuab yog cov ntsuas kub feem ntau siv kub tshaj plaws. Hauv qab no yog cov lus qhia ntxaws ntxaws rau peb hom ntawm qhov kub thiab txias.

1. Thermocouple: muaj ntawm ob qho kev sib xyaw nrog cov hlau sib xyaw walded ua ke los ua ob lub junctions. Qhov ntsuas kub sib txawv ntawm cov nodes yuav tsim kom muaj cov peev xwm thermoelectric (piv txwv li voltage) nruab nrab ntawm ob xaim. Los ntawm kev tswj hwm qhov ntsuas ntawm lub tshuab paub kub thiab ntsuas qhov ntsuas hluav taws xob thaum cov txheej txheem, ntsuas kub ntawm kev kuaj pom ntawm node tuaj yeem ua tau zoo. Qhov zoo ntawm thermocouples yog tias lawv muaj ntau txoj haujlwm kub thiab lub cev me me. Txawm li cas los xij, lawv kuj muaj qhov tsis zoo xws li cov zis qis heev, muaj peev xwm ua tau lub suab nrov los ntawm cov voj hlau, thiab nrawm.

2. Tiv thaiv tus pas ntsuas kub (RTD)

Nws yog cov hlau coiled los yog nyias zaj duab xis muab kauv raj uas yuav ua tau cov kev hloov pauv ntawm tus nqi tiv thaiv nrog kub. Txawm hais tias feem ntau siv cov hlau muaj xws li tooj liab muaj xws li tooj liab, thiab npib tsib xee, rtds ua cov platinum ua kom zoo nkauj, rov ua dua, thiab ruaj khov. Cia siab rau nws zoo linearity

Nrog kev ruaj ntseg ib ntus ntawm *, platinum rtd khov kho nws txoj hauj lwm ua qhov ntsuas kub thiab txias siv rau kuv. Although thin-film platinum RTDs provide functional matching, scale grade wire wound resistors are superior in terms of cost, shape, size, and convenience. Cov theem lig-ua yeeb yaj kiab Platinum RTDs yog plaged los ntawm drift vim lawv cov nominal ntim sib xws, ua rau lawv paub ntau zuj zus. Tom qab, kev txhim kho ntawm zaj duab xis txiav thiab ntim tshem tawm cov kev ua tiav no, ua yeeb yaj kiab RTD cov kab mob hlau thiab NTC thermicors thiab ua kom sov siab.

3. NTC thermistor

Sau ntawm cov hlau oxide ceramics, nws yog tus nqi qis thiab ntsuas kub siab heev. Nyob rau tib lub sijhawm, lawv kuj yog qhov ntsuas kub nrog kab sib txawv thiab muaj qhov kub thiab txias coefficients. Tus cua kub muaj ntau cov duab thiab ntau thiab tsawg, cov hauv paus puas tsuaj, uas tuaj yeem siv rau kev txuas thiab tso tawm cov kab tawm hauv tsheb.
