PR1231/PR1232 Platinum-10% Rhodium/Platium Thermocouple
PR1231/PR1232Platinum e tloaelehileng-10% Rhodium / Platium Thermocouple
Part1 Overview
Li-thermocouples tsa sehlopha sa pele le sa bobeli sa platinum-iridium 10-platinum tse nang le thepa e ntle ea 'mele le lik'hemik'hale tse nepahetseng, ho hanyetsa oxidation e ntle ka mocheso o phahameng, botsitso bo botle le ho ikatisa ha matla a thermoelectromotive.Ka hona, e sebelisoa e le sesebelisoa sa ho lekanya se tloaelehileng ho (419.527 ~ 1084.62) °C, e boetse e sebelisetsoa ho fetisa boholo ba mocheso le tekanyo e nepahetseng ea mocheso sebakeng sa mocheso.
