Yuav ua li cas txheeb xyuas lub Platinum Rhaurodium cov ntsiab lus ntawm ib thermocouple?

Rau s-nplai thermocouple platinuple Rhodium alloy hlau, rhodium muaj 10%; Rau platinum rhodium alloy hlau ntawm r nplai thermocouple, microdium muaj 13%; Rau b-qib thermocouple platinoup rhodium alloy hlau, cov hlau zoo muaj 30% rho tawm muaj 30% rho tawm 6% rho tawm.

Siv lub khob roj cav, sim ua kom sov nws, ntxig ib khob raj ntsuas cua nab mercury ntsuas pa taws thiab ua kom sov roj thiab ua kom sov rau 200 degree. Ntxig qhov kawg ntawm thermocouple raug sim mus rau hauv cov roj thiab teeb plaub-thiab-ib-ib-precolision ntau yam (siv lub siab-precivolt ntsuas yog qhov zoo dua).

1. Kev nyeem ntawv ntsuas los ntawm cov digital pultimeter yog 1.441 millivolts, uas yog platinum thread ntawm s-nplai thermocouple, muaj 10% rhodium.

2. Kev nyeem ntawv ntsuas los ntawm cov digital pulloimeter yog 1.469 millivolts, uas yog lub platinum micro dai dej thiab kev sojntsuam liab, muaj 13% rhodium.

3. Kev nyeem ntawv ntsuas los ntawm cov digital multimeter yog {}}. 178 millivolts, uas yog b scale thermocouple. Lub Platinum Rhodium alloy hlau (zoo electrode) hauv kev sib cuag nrog cov kev sib tw liab (tsis zoo rau hluav taws xob (tsis zoo rau hluav taws xob)

Ntawm chav kawm, cov roj kub tuaj yeem raug tsa mus rau 300 degree, thiab S thiab R Caliburation thermocouples tuaj yeem zoo dua.

1. Kev nyeem ntawv ntsuas los ntawm cov digital pultimeter yog 2.323 millivolts, uas yog platinum throde ntawm s-scale thermocouple, muaj 10% rhodium.

2. Kev nyeem ntawv ntsuas los ntawm cov digital multimeter yog 2.401 hmoov nplej, uas yog lub Platinum

3. Kev nyeem ntawv ntsuas los ntawm cov digital multimeter yog {1}}. 431 millivolts, uas yog b scale thermocouple. Lub Platinum Rhodium alloy hlau (zoo electrode) hauv kev sib cuag nrog cov kev sib tw liab (tsis zoo rau hluav taws xob (tsis zoo rau hluav taws xob)
