Domain metrologymeasuring instruments
  • elektriline mõõtevahend (põhimõtteliselt voolumõõtur), milles mõõdetav vool läbib peenikese traadi ja põhjustab selle temperatuuri tõusu
  • electrical measuring instrument (basically an ammeter) in which the current to be measured is passed through a thin wire and causes its temperature to rise
  • instrument which operates by the heating effect(s) od (a) current(s) on it(s) conductor(s)
soojusmõõtevahend preferred
Usage examples
  • Soojusmõõtevahendis läbib vool traati, mis kuumenedes jämeneb, ja kuigi neil mõõtevahenditel on aeglane reageerimisaeg ja madal täpsus, kasutati neid mõnikord raadiosagedusliku voolu mõõtmiseks.
hot-wire instrument preferred
Usage examples
  • In a hot-wire instrument, a current passes through a wire which expands as it heats, and although these instruments have slow response time and low accuracy, they were sometimes used in measuring radio-frequency current.
thermal instrument
