Second standard thermocouple (WRPB-2, WRRB-2) standard platinum-rhodium 10 - platinum thermocouple positive (SP) containing 10% rhodium alloy of platinum and rhodium, negative (SN) is a pure platinum, 550 mm long sleeve top The holes insulating ceramic tube; reference upright pole sleeve red or pink plastic pipe, the negative sleeve white or blue plastic pipe; the whole branch product in ordinary glass outer tube and save. Second-class standard platinum and rhodium 30- platinum and rhodium 6 thermocouple positive (SP) for 30% of the platinum-rhodium alloy rhodium thermocouple wear Cement, negative (SN) containing rhodium 6% of platinum-rhodium alloy wearable thermoelectric cement plant Even quoted above sets have holes insulating ceramic tube length 550 mm; see upright pole sleeve red or pink plastic pipe cement plant wearable thermocouple selection, negative sleeve white or blue plastic pipe; the whole branch product in the ordinary glass Save jacket tube. Cement special thermocouple thermocouple insulation resistance (at room temperature) at room temperature insulation resistance test voltage DC 500V ± 50V Cement prices wearable thermocouple to measure atmospheric conditions at room temperature insulation resistance temperature 15 ~ 35 ℃, relative humidity of 45%. For longer than 1 meter thermocouple, its temperature insulation resistance value is not less than the product of its length 100MΩm. That Rr L≥100 MΩm L> 1m formula: Rr- thermocouple temperature insulation resistance value, the length of L- thermocouple. For the length equal to or less than one meter of thermocouple, its temperature insulation resistance value should not be less than 100MΩ.
