Qhov ntsuas kub tsis tu ncua
Lub ntsuas kub ntsuas tsis zoo yog lub ntsuas hluav taws uas ua kom muaj lub suab ceeb toom thaum qhov kub nce los ntawm qhov hluav taws kub tshaj qhov txiaj ntsig nyob hauv lub sijhawm teev tseg. Nws muaj ob hom qauv: hom kab thiab hom taw tes. Cov hom kab yog tias thaum qhov chaw ntsuas thaj chaw hauv cheeb tsam nce mus rau tus nqi uas tau teev tseg, lub fusible rwb thaiv tsev melts thiab luv luv ntawm ob txoj xov hluav taws xob, yog li tsim hluav taws xob teeb liab. Point-type tsau ntsuas siv hluav taws xob siv bimetal, fusible hlau, thermocouples, thermo-rhiab semiconductor resistors thiab lwm yam khoom siv los tsim hluav taws kub lub teeb liab ntawm tus nqi ntsuas kub.
