Cov hlau tsis kam yog ib qho tseem ceeb ntawm ntau yam khoom siv hluav taws xob thiab hluav taws xob thiab ua ntau yam haujlwm tseem ceeb rau lawv txoj haujlwm. Lub luag haujlwm tseem ceeb ntawm cov hlau tsis kam yog thaiv cov hluav taws xob ntws, yog li hloov lub zog hluav taws xob mus rau hauv cua sov. Cov yam ntxwv no ua rau cov hlau tsis kam tseem ceeb hauv cov ntawv thov xws li cov khoom siv cua sov, kev tiv thaiv Circuit Court, thiab cov kab ke tswj kub.

Ib qho ntawm cov kev siv ntau tshaj plaws rauhlau tsis kamyog nyob rau hauv cov khoom cua sov, uas yog siv los tsim cua sov rau ntau yam kev siv. Txij li cov qhov cub hluav taws xob thiab qhov cub mus rau cov qhov cub kev lag luam thiab cov cua sov chaw, cov hlau tsis kam ua lub luag haujlwm tseem ceeb hauv kev hloov lub zog hluav taws xob mus rau hauv cua sov. Cov hlau tsis kam muaj peev xwm tiv taus qhov kub siab thiab nws cov conductivity zoo heev ua rau nws zoo tagnrho rau kev siv cua sov.

Ntxiv rau lawv lub luag haujlwm hauv cov khoom cua sov, cov xov hlau tiv thaiv kuj tseem siv rau hauv cov khoom siv tiv thaiv hluav taws xob xws li fuses thiab circuit breakers. Thaum cov hluav taws xob ntau dhau ntws hauv lub voj voog, cov xov hlau tiv thaiv ntawm lub fuse kub thiab yaj, ua rau lub voj voog tawg thiab tiv thaiv kev puas tsuaj rau cov khoom siv txuas nrog. Ib yam li ntawd, hauv cov circuit breakers, cov xov hlau tiv thaiv tau tsim los ua kom tawg thiab tawg lub voj voog thaum muaj kev thauj khoom ntau dhau, yog li tiv thaiv lub kaw lus hluav taws xob ntawm kev phom sij.

Tsis tas li ntawd xwb, cov hlau tiv taus yog ib feem tseem ceeb ntawm kev ua haujlwm ntawm lub kaw lus tswj qhov kub thiab txias rau cov khoom siv xws li thermistors thiab thermocouples. Thermistors yog cov resistors uas rhiab heev rau qhov kub thiab txias uas siv cov hlau tiv taus los ntsuas thiab tswj qhov kub thiab txias hauv cov ntawv thov xws li cov tshuab tswj cav tsheb mus rau cov khoom siv kho mob. Ib yam li ntawd, cov thermocouples siv cov hlau tiv taus los ntsuas qhov sib txawv ntawm qhov kub thiab hloov lawv mus rau hauv cov teeb liab hluav taws xob, uas ua rau lawv tseem ceeb rau kev saib xyuas qhov kub thiab txias thiab kev tswj hwm hauv cov txheej txheem kev lag luam thiab kev tshawb fawb.

Qhov ua tau ntau yam ntawmcov xov hlau tiv thaivtxuas ntxiv mus rau lawv siv rau hauv cov khoom siv hluav taws xob xws li resistors, uas yog siv los tswj cov tam sim no hauv lub voj voog. Los ntawm kev muab ib qib tshwj xeeb ntawm kev tiv thaiv, cov xov hlau tiv thaiv tuaj yeem tswj tau cov yam ntxwv hluav taws xob ntawm lub voj voog, ua rau lawv yog ib qho tseem ceeb hauv cov khoom siv hluav taws xob thiab cov kab ke.

Tsis tas li ntawd xwb, cov xov hlau tiv thaiv tau siv rau hauv cov teb tshwj xeeb xws li aerospace thiab kev tiv thaiv, qhov twg lawv qhov kev ntseeg tau thiab kev ua tau zoo nyob rau hauv cov xwm txheej hnyav yog qhov tseem ceeb. Hauv kev siv aerospace, cov xov hlau tiv thaiv tau siv rau hauv cov tshuab cua sov, cov tshuab de-icing thiab cov kev daws teeb meem thermal rau cov khoom siv dav hlau. Lawv lub peev xwm los tiv taus qhov kub siab thiab qhov chaw ib puag ncig hnyav ua rau lawv zoo tagnrho rau kev ua haujlwm zoo thiab muaj kev nyab xeeb ntawm cov tshuab aerospace.

Qhov tseem ceeb ntawm cov hlau tiv taus hauv ntau yam lag luam thiab daim ntawv thov qhia txog nws qhov tseem ceeb hauv kev siv tshuab niaj hnub no. Nws lub peev xwm hloov lub zog hluav taws xob mus rau hauv cua sov, tswj cov tam sim no thiab pab tswj qhov kub ua rau nws yog ib qho tseem ceeb hauv kev ua kom sov, hluav taws xob thiab hluav taws xob. Thaum thev naus laus zis txuas ntxiv mus, qhov kev thov rau cov hlau tiv taus ua haujlwm siab nrog cov yam ntxwv zoo dua yuav txuas ntxiv loj hlob, ntxiv dag zog rau lawv lub luag haujlwm hauv cov khoom siv thiab cov kab ke uas muaj zog rau lub ntiaj teb niaj hnub no.
