Kev piav qhia txog khoom
Cov thermocouples hom R, S, thiab B yog cov thermocouples "Noble Metal", uas yog siv rau hauv cov ntawv thov kub siab.
Hom S thermocouples yog tus cwj pwm los ntawm qib siab ntawm kev tsis muaj zog tshuaj lom neeg thiab kev ruaj khov ntawm qhov kub siab. Feem ntau siv ua tus qauv rau kev ntsuas cov thermocouples hlau puag.
Platinum rhodium thermocouple (S/B/R hom)
Platinum Rhodium Assembling Type Thermocouple siv dav hauv cov chaw tsim khoom nrog qhov kub siab. Nws yog siv los ntsuas qhov kub hauv kev lag luam iav thiab ceramic thiab kev lag luam salting.
Cov khoom siv rwb thaiv tsev: PVC, PTFE, FB lossis raws li tus neeg siv khoom xav tau.
Daim ntawv thov ntawmhlau thermocouple
• Kev Ua Kub - Cov roj hlawv rau qhov cub
• Txias - Lub Tub Yees
• Kev tiv thaiv cav - Kub thiab kub ntawm qhov chaw
• Kev tswj kub siab - Kev ua hlau casting
