Matšeliso a phahameng a CJ
Ho tsitsa le ho nepahala ha mocheso oa CJ ho bapala karolo ea bohlokoa ho lekanya li-thermocouples tse nepahetseng haholo.Limithara tsa dijithale tse sebelisoang hangata tse nepahetseng haholo li hloka ho kopanngoa le lisebelisoa tse khethehileng tsa matšeliso a CJ bakeng sa tekanyo ea thermocouple.Mojule oa matšeliso a Phahameng ka ho Fetisisa oa CJ o kenyelelitsoe ho PR293 series thermometers, kahoo phoso ea CJ ea mocha o sebelisitsoeng o molemo ho feta 0.15 ℃ ntle le lisebelisoa tse ling e ka phethahala.
Mesebetsi e ruileng ea metrology ea mocheso
Li-thermometers tsa PR291/PR293 ke sesebelisoa se ikhethileng sa tlhahlobo se etselitsoeng indasteri ea metrology ea mocheso.Ho na le mekhoa e meraro e sebetsang ea ho fumana, ho latela mocha o le mong, le tekanyo ea phapang ea mocheso, eo har'a eona mokhoa oa ho lekanya phapang ea mocheso o ka hlahlobang ho tšoana ha mocheso oa mefuta eohle ea lisebelisoa tsa mocheso tse sa khaotseng.
Ha ho bapisoa le multimeter ea setso ea dijithale, ho kenyelletsoa mefuta e mengata ea 30mV ka ho khetheha bakeng sa ho metha li-thermocouples tsa mofuta oa S le 400Ω bakeng sa tekanyo ea khanyetso ea platinamo ea PT100.'Me ka mananeo a ho fetola a hahelletsoeng ka har'a li-sensor tse fapaneng tsa mocheso, li-sensor tse fapaneng (joalo ka li-thermocouples tse tloaelehileng, li-thermometers tse tloaelehileng tsa platinamo, li-thermometers tsa platinamo tsa indasteri le li-thermocouples tse sebetsang) li ka tšehetsoa,' me data ea setifikeiti kapa lintlha tsa tokiso li ka hlalosoa ho latela mohlala. mocheso oa liphetho tsa liteko.
Mosebetsi oa ho hlahloba lintlha
Ntle le lintlha tse fapaneng tsa liteko, li-curve le polokelo ea data li ka bonts'oa, boleng ba data ba nako ea nnete bo boholo / bonyane / karolelano, lintlha tse fapaneng tsa botsitso ba mocheso li ka baloa, 'me lintlha tse phahameng le tse fokolang li ka tšoauoa ho thusa tlhahlobo ea data e hlakileng. setšeng sa teko.
Moqapi o nkehang
Limitara tsa dijithale tsa boleng bo holimo tse sebelisoang hangata lilaboratoring li kholo ebile ha li nkehe.Ka lehlakoreng le leng, li-thermometer tsa PR291/PR293 li nyane ka bophahamo le boima ba 'mele, tse loketseng tlhahlobo ea mocheso oa maemo a holimo libakeng tse fapaneng tsa sebaka sa marang-rang.Ntle le moo, moralo oa betri ea lithium e nang le matla a maholo le eona e etsa hore ts'ebetso e be bonolo.
