A common wire-wound platinum resistance temperature sensor wraps platinum wires around the ceramic or plastic skeleton and cannot meet the requirements of high temperature test and vibration resistance. In this paper, a special platinum resistance dual-channel temperature sensor with high temperature resistance, good insulation, high temperature measurement accuracy and high reliability has been trial-produced and its scale mark can satisfy BA2. It adopts stainless steel skeleton as matrix material, and high temperature resistant insulating material is wrapped on the skeleton. After that, four high-purity platinum wires with the diameter of 0.04 mm are bound on the skeleton in a parallel way. The platinum wires almost cling to the surface of the stainless steel skeleton, which can reflect the actual temperature of the measured medium more accurately and rapidly than the general axial thermal resistor. The sensor can output two groups of the same resistance signal for use at the same time with agile response and dual redundant.
