Joalokaha bohle re tseba, mosebetsi o ka sehloohong oa li-thermocouples ke ho lekanya le ho laola mocheso. Li sebelisoa haholo liindastering tse kang petrochemical, meriana le tlhahiso. Lits'ebetsong tsa indasteri, tlhahlobo e nepahetseng ea mocheso e amana haufi-ufi le taolo ea boleng ba sehlahisoa le ntlafatso ea ts'ebetso ea ts'ebetso. Ka hona, terata ea platinum-rhodium thermocouple ke khetho e tšepahalang le e nepahetseng har'a mefuta e mengata ea lihlahisoa.
Empa ke engterata ea platinum-rhodium thermocouple? Ho hlakile hore ke thermocouple e entsoeng ka litšepe tse peli tsa bohlokoa, platinum le rhodium, tse etselitsoeng ka ho khetheha ho mamella mocheso o phahameng le ho fana ka tekanyo e nepahetseng ea mocheso tlas'a maemo a feteletseng. Litšepe ka bobeli li khethiloe ka hloko bakeng sa lintlha tse phahameng tsa ho qhibiliha, ho hanyetsa kutu le mocheso o pharaletseng. Mefuta e tloaelehileng ka ho fetisisa ea terata ea platinum-rhodium thermocouple eo re e bonang ke S-mofuta (platinum-10% rhodium / platinum) le mofuta oa R (platinum-13% rhodium / platinum) thermocouples.
Platinum-rhodium thermocouple terata e na le litšobotsi tse 'maloa tsa bohlokoa. Ntlha ea pele, terata ea platinum-rhodium thermocouple e ka mamella mocheso ho fihlela ho 1600 ° C (2912 ° F), e etsa hore e tšoanelehe bakeng sa lisebelisoa tse phahameng tsa mocheso tse kang ho sebetsa ho chesang, ho hlahloba sebōpi le ho etsa lifofane. Taba ea bobeli, ho kopanngoa ha platinum le rhodium terata ea thermocouple ho tiisa botsitso le ho pheta-pheta ha tekanyo ea mocheso, esita le tlas'a maemo a thata a ho sebetsa. Ntle le moo, terata ea platinum-rhodium thermocouple e boetse e na le khanyetso e matla ea kutu, hammoho le nako ea karabelo e potlakileng, mme terata e ka fihlela tekanyo e potlakileng le e nepahetseng ea mocheso, e leng bohlokoa lits'ebetsong tse matla tsa indasteri.
Platinum-rhodium thermocouple terata e sebelisoa haholo masimong a indasteri a nang le litlhoko tse phahameng haholo bakeng sa ho metha le ho laola mocheso o phahameng. Ka mohlala, indastering ea phekolo ea mocheso, terata ea platinum-rhodium thermocouple e sebelisetsoa ho shebella le ho laola mocheso oa libōpi, lionto le mekhoa ea phekolo ea mocheso ho netefatsa hore thepa e hlokahalang ea thepa e finyelloa. Ho feta moo, indasteri ea lifofane e itšetlehile ka terata ea platinum-rhodium bakeng sa ho beha leihlo mocheso o nepahetseng nakong ea ts'ebetso ea ho etsa likarolo tsa lifofane, likarolo tsa enjene le lisebelisoa tse ling tsa bohlokoa tsa sefofane. Indasteri ea tlhahiso ea likhalase le tsa ceramic e e sebelisa ho lekola mocheso oa libopi le libopi tse sebelisoang ha ho etsoa likhalase, lirafshoa le lisebelisoa tsa refractory.
Ka bokhutšoane,terata ea platinum-rhodium thermocoupleke sesebelisoa sa bohlokoa bakeng sa tekanyo e nepahetseng ea mocheso le taolo lefapheng la indasteri ea mocheso o phahameng. Tshebetso ea eona e babatsehang, mocheso o pharaletseng le ho tšepahala ho etsa khetho ea pele bakeng sa liindasteri tse nang le litlhoko tse phahameng haholo bakeng sa ho nepahala le botsitso. Hore na o kenya letsoho ho phekola mocheso, tlhahiso ea sefofane, ts'ebetso ea petrochemical, kapa liindasteri tse ling tse hlokang litekanyo tsa mocheso o phahameng, terata ea platinum-rhodium thermocouple e fana ka ho nepahala le ho tšoarella ho hlokahalang ho netefatsa ts'ebetso e nepahetseng ea ts'ebetso le boleng ba sehlahisoa.
