提高工业电阻测温准确性和稳定性的传统手段都在元件纯度、封装技术、制作流程上下功夫;则从计算方法上给出了新思路,为精密铂电阻和工业铂电阻在温度量值传递和溯源体系的完善奠定了基础,可广泛应用于工业PT100铂电阻的测温领域。

测温技术

pt100redianzuyuputongxingredianzuxiangbi,tayouxialieyoudian:

·热响应时间短,减小动态误差;
·直径小,长度不受限制(三线制电阻受线长影响小);
·测量精度高,绍兴中仪的PT100热电阻均采用德国进口A级电阻,性能可靠稳定;
·统一设计产品,接口尺寸通用,互换性好;
·采用装配式结构,零件分解性好,维修方便;更换易损件成本低;
·体积小,内部无空气隙,热惯性上,测量滞后小;
·机械性能好、耐振,抗冲击;
·铠装式能弯曲,便于安装;
·使用寿命长。

绝缘电阻装配铂热电阻的常温绝缘电阻应不小于100MΩ,常温绝缘电阻的试验电压为10~100V DC。自热影响: 铂电阻允许通过的最大电流为5mA,由此产生的温升不大于0.3℃。热响应时间: 在温度出现阶跃变化时,热电阻的输出变化至相当于该阶跃变化的50%,所需要的时间,称为热响应时间,用τ0.5表示。热电阻时间常数热惰性级别时间常数(秒)热惰性级别时间常数(秒)Ⅰ90-180Ⅲ10-30Ⅱ30-90Ⅳ10。
  热电阻的公称压力: 一般是指在工作温度下保护管所能承受的静态外压而不破裂。热电阻最小插入深度: 应不小于其保护套管外径的8-10倍。绝缘电阻: 当周围空气温度为15-35℃,相对湿度<80%时,绝缘电阻20兆欧(电压100V)。具有防溅式接线盒的绝缘电阻应2兆欧(电压100V)热电阻感温元件在0℃ 时电阻值(R0)及其与在100℃  时的电阻值(R100)比值: 比值=R100/R分度号为Pt10、Pt100时;R100/R0=1.3850±0.001分度号为Cu50、Cu100时;R100/R0=1.3850±0.002
