Standard Platinum Resistance Thermometer

Standard Platinum Resistance Thermometer

I. Tsanangudzo

Iyo Standard Platinum Resistance Thermometer inoshandiswa kuripa mune yakajairwa tembiricha renji ye13.8033k—961.8°C, uye inoshandiswa seyakajairwa paunenge uchiyedza akasiyana siyana mathermometers uye yakakwirira-chaiyo mathermometers.Mukati meiyo iri pamusoro petembiricha zone, inoshandiswawo zvakananga kuyera tembiricha yepamusoro-yechokwadi.

Iyo Standard Platinamu Resistance Thermometer inoyera tembiricha zvinoenderana neinochinjika yakajairika yekupikisa tembiricha yeplatinamu.

Zvinoenderana nemirairo yeITS90, iyo T₉₀inotsanangurwa ne platinamu thermometer apo katatu (13.8033K) yenitrogen balance yasvika kune tembiricha yesirivheri yechando.Iyo inonongedzwa nekushandisa boka reinodiwa inotsanangurwa yechando nzvimbo uye referensi basa pamwe nekutsauka basa rekushisa kupindirana.

Iyo yekumusoro tembiricha zoning yakakamurwa kuita akati wandei uye yakafunga kushanda zvakajairwa mukati me sub-tembiricha zone nenzira dzakasiyana siyana dzechimiro che thermometers.

Ona iyo yakadzama thermometers patafura pazasi:

Ongorora: Iyo Rtp yemathermometers ari pamusoro ndeye makumi maviri neshanu±1.0Ω.Kunze kwedhayamita yemachubhu equartz ndiko φ7±0.6mm.fekitari yedu inogadzirawo thermometer yeplatinamu ine tembiricha ye83.8058K~660.323℃sechishandiso chechiyero chekushanda.

1. Usati washandisa, chekutanga, tarisa iyo thermometer nhamba kuti ienderane nechitupa chebvunzo.

2. Paunenge uchishandisa, zvinoenderana neiyo lug logo yeiyo thermometer waya terminal, batanidza waya nemazvo.Iyo lug① yewaya dzvuku yakabatana kune yazvino yakanaka terminal;the lug③yeyero waya, kune yazvino inegetive terminal;uye lug②yewaya nhema, kune inogona kuita yakanaka terminal;the lug④yewaya yakasvibira, kune inogoneka yakaipa terminal.

Iyo inotevera rondedzero ye thermometer:

3. Ikozvino inofanira kunge iri 1MA zvichienderana nekuyera kwechikamu chekushisa che thermometer.

4. Pakuenzanisa mudziyo wemagetsi wekuyera thermometer yekuyeresa tembiricha, iyo yakaderera kuramba potentiometer yegiredhi 1 uye yakajairwa coil kuramba yegiredhi 0.1 kana yekuyera chaiyo tembiricha bhiriji pamwe nemidziyo inofanirwa kushandiswa.Iyo yakazara seti yemagetsi yekuyera mudziyo unofanirwa kuvimbiswa kuve nekunzwa kusiyanisa shanduko yeimwe gumi-chiuru Ohm.

5. Munguva yekushandiswa kwekushandisa, kuchengetedza uye kutakura, edza kudzivirira iyo yakanyanya mechanical vibration ye thermometer.

6. Paunenge uchishandisa giredhi rekutanga Standard Platinum Resistance Thermometer kuyedza tembiricha yegiredhi rechipiri Standard Platinum Resistance Thermometer, inofanirwa kutevedzera maitiro ekuona anotenderwa neNational Measurement Bureau.

7. Muedzo wenguva dzose weiyo thermometer unofanirwa kuitwa zvine simba zvichienderana neakakodzera maitiro ekusimbisa uye mirau.
