Mechanical thiab hluav taws xob,
Txhua yam txheej uas muaj ob txheej uas txawv thermal expansion coefficient ntawm cov hlau ua ke, qhov hloov pauv, yuav pauv nws cov khoov thaum nws khoov rau qee qhov, qhov txuas (los yog kaw), qhov cua txias (lossis cua sov).
Electronically ntawm thermocouples, platinum kuj kub kub sensor teeb liab mus rau hluav taws xob teeb liab, tswj los ntawm microcontroller, PLC, circuit relay ua rau cov cua kub (lossis txias) khoom (los yog tso tseg).
Nws muaj qhov ntsuas kub ntawm Mercury, kub kom muaj kev sib chwv thiab mercury hloov
