annex:
Four-wire platinum resistance (PT100) temperature sensor (length standard is 5 meters):
Low temperature line: the use range is -60 ~ 230 ℃, the advantages are thin line, good flexibility, waterproof, anti-corrosion, not easy to break, pass through the door of the tested equipment without affecting the seal, to ensure the accuracy of the test data The use range is -100 ～ 300 ℃, the outer diameter is 5㎜, and it is wrapped with a metal shield layer. The advantages are strong anti-interference ability, high temperature resistance, waterproof and anti-corrosion. The disadvantage is that the wire diameter is thick, which affects the tightness of the tested equipment : Use range 0 ～ 450 ℃, outer diameter is 5㎜, wrapped with metal shielding layer, the advantage is strong anti-interference ability, high temperature resistance, the disadvantage is thick wire diameter, not waterproof. Measurement accuracy: ± 0.1% + 0.05 ℃
