WZPK-225/WZPK-226PT100铠装铂热电阻
产品概述:
热电阻（thermal resistor）是中低温区常用的一种温度检测器。热电阻测温是基于金属导体的电阻值随温度的增加而增加这一特性来进行温度测量的。WZPK-225/WZPK-226PT100铠装铂热电阻主要特点是测量精度高，性能稳定。其中铂热电阻的测量精确度是高的，它不仅广泛应用于工业测温，而且被制成标准的基准仪。WZPK-225/WZPK-226PT100铠装铂热电阻大都由纯金属材料制成，目前应用多的是铂和铜，此外，现在已开始采用镍、锰和铑等材料制造热电阻。金属热电阻常用的感温材料种类较多，常用的是铂丝。工业测量用金属热电阻材料除铂丝外，还有铜、镍、铁、铁—镍等。
WZPK-225/WZPK-226PT100铠装铂热电阻工作原理:
热电阻的测温原理是基于导体或半导体的电阻值随温度变化而变化这一特性来测量温度及与温度有关的参数。热电阻大都由纯金属材料制成，目前应用多的是铂和铜，现在已开始采用镍、锰和铑等材料制造热电阻。热电阻通常需要把电阻信号通过引线传递到计算机控制装置或者其它二次仪表上。
偶丝直径材料:
常温绝缘电阻: 热电阻在环境温度为15—35°C，相对湿度不大于80%，试验电压为10—100V（直流）电极与外套管之间的绝缘电阻>100MΩ。 WZPK铠装热电阻测温范围及温差:
