PR1231/PR1232Paerewa Platinum-10% Rhodium/Platium Thermocouple
Wāhanga1 Overview
Ko te tuatahi me te tuarua o nga paerewa konukawata-iridium 10-platinum thermocouples e tika ana te pai o nga ahuatanga o te tinana me te matū, he pai te aukati i te waikura i te teitei o te wera, te pai o te pumau me te whakahou o te kaha thermoelectromotive.Na reira, ka whakamahia hei taputapu ine paerewa i roto i te (419.527~1084.62) °C, ka whakamahia hoki ki te whakawhiti i te nui o te pāmahana me te ine ine pāmahana tika i roto i te awhe pāmahana.

Wāhanga 4 Te tiaki me te tiaki
1. Ko te waa whakamaarama o te thermocouple paerewa ko te 1 tau, a ia tau me whakatauhia te thermocouple paerewa e te tari metrology.
2. Me mahi te whakatikatika i runga i te whakamahinga.
3. Ko te taiao mahi o te thermocouple paerewa kia ma ki te karo contamination o te thermocouple paerewa.
4. Me whakanoho te thermocouple paerewa i roto i te ahua kore-pollution me te tiaki i te ahotea miihini.
Wāhanga 5 Nga Whakatupato ina whakamahi
1. Kaore e taea te whakamahi i te ngongo whakamatao ki te tunu wera.Ka whakamahia te ngongo whakamaarama taketake i muri i te tino horoi me te tunu wera nui.
2. Ka warewarehia e te ngongo whakamatao te pai me te kino, ka poke te pou konukawata, ka heke te uara o te thermoelectric.
3. Ka whakapokea e te ngongo whakamatao whakamaarama paerewa me te waea iti te thermocouple paerewa, a me whakamahi te ngongo whakarewa whakamarumaru mo te manatoko o te thermocouple whakarewa turanga.
4. Ko te thermocouple paerewa e kore e taea te whakanoho ohorere ki roto i te oumu whakahaere pāmahana, kaua hoki e tangohia mai i te oumu whakahaere pāmahana.Ko te wera ohorere me te makariri ka pa ki te mahi thermoelectric
5.I raro i nga ahuatanga noa, ko te oumu whakapumau mo te thermocouple whakarewa utu nui me te thermocouple whakarewa turanga me tino tohu;ki te kore e taea, me whakauru te ngongo uku ma, ngongo corundum ranei (te diameter tata ki te 15mm) ki te ngongo oumu hei tiaki i nga Thermocouple whakarewa utu nui me nga thermocouples paerewa mai i te parahanga whakarewa werawera.
