1.WZPK系列铠装铂电阻测量范围和允差
| 热电阻类别 | 测量范围(℃) | 分度号 | 允差t(℃) |
| WZP型铂电阻 | -200~+420 | Pt100 | *±(0.15+0.00 2|t|) |
| B级±(0.30+0.00 5|t|) |
2.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%,所需的时间,称为热响应时间,用τ0.5表示。
3.绝缘电阻
常温绝缘电阻的试验电压可取直流10~100V任意值,环境温度在12~35℃范围内,相对湿度应不大于80%;常温绝缘电阻值应不小于100MΩ。
4.自热影响
热电阻允许通过的大测量电流为5mA,由此产生的温升不大于0.3℃。
