Jeoro Amapereka Mitundu Yosiyanasiyana Yakutentha
Ma transmitters osinthika samangosamutsa ma siginecha otembenuka kuchokera ku resistance thermometers (RTD) ndi thermocouples (TC), amasamutsanso ma siginecha okana (Ω) ndi ma voltage (mV).Kuti mupeze kulondola kwapamwamba kwambiri, mawonekedwe a mzere wamtundu uliwonse wa sensa amasungidwa mu transmitter.Pochita izi, mfundo ziwiri zoyezera kutentha zadzitsimikizira ngati muyezo:
RTD - Zowunikira kutentha kwa Resistance
Sensa ya RTD imasintha kukana kwamagetsi ndi kusintha kwa kutentha.Ndioyenera kuyeza kutentha kwapakati pa -200 °C ndi pafupifupi.600 ° C ndikuwoneka bwino chifukwa cha kuyeza kwake komanso kukhazikika kwanthawi yayitali.Sensa yomwe imagwiritsidwa ntchito kwambiri ndi Pt100.
TC - Thermocouples
Thermocouple ndi chigawo chopangidwa ndi zitsulo ziwiri zosiyana zolumikizana wina ndi mzake pamapeto amodzi.Ma Thermocouples ndi oyenera kuyeza kutentha kwapakati pa 0 °C mpaka +1800 °C.Iwo amawonekera chifukwa cha nthawi yoyankha mwachangu komanso kukana kugwedezeka kwakukulu.
