Temperature measuring copolar R-type four-couple structure

The invention belongs to the thermocouple temperature measuring technology and particularly relates to a temperature measuring copolar R-type four-couple structure, which comprises a spherical joint (1), a platinum iridium 13 (R1+) electrode (2), a platinum (R1-) electrode ( 3), a platinum rhodium 13 (R2+) electrode (4), and a platinum (R2-) electrode (5). At the same measuring point, the copolarR-type four-coupler can obtain four groups of temperature values at a time, achieves mutual verification and evidence, and can reduce a temperature measurement error. The temperature measuring copolarR-type four-couple structure solves the influence of heat flow shock and vibration on the strength and the temperature measurement precision of a monopole double-couple in engineering application, and improves the temperature measurement reliability of a temperature sensor. The temperature measurement technology has the characteristics of multiple margins and reliable structure, and can be applied to gas temperature measu
