| 一般的线绕式铂电阻温度传感器都是将铂丝缠绕在陶瓷骨架或塑料骨架上，难以同时满足高温测试和耐振动冲击机械环境的要求。本文试制了一种耐高温，绝缘性好，测温精度高，可靠性强，分度号满足BA2（22A）型铂电阻的特殊的双通道温度传感器。它的骨架采用不锈钢为基体材料，经过耐高温绝缘材料进行处理后，将直径为0.04mm的高纯度铂丝采用四线并绕的方式绕制于骨架上。铂丝几乎紧贴在不锈钢骨架表面，与一般轴向热电阻相比，更能正确和迅速地反映被测介质的实际温度。它可以同时输出两组相同的电阻信号供使用，具有响应速度快、双裕度等特点。 |
| 英文摘要: |
| 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. |
