2011-9-13 16:44:05

Brief introduction of armored thermal resistance
    东祥仪表 有限公司生产WZPK 系列铠装热电阻测量温元件,具 有以下 优点 精确 灵敏 热响应时间快 质量稳定 使用寿命长等 Jiangsu Dongxiang Instrument Co., Ltd. produces WZPK series armored thermal resistance measuring temperature elements, which have the following advantages : accuracy , sensitivity , fast thermal response time , stable quality , and long service life . 是一种温度传感器,它比装配式铂电阻 直径 小, 易弯曲,抗震性好, 而且 适宜安装在装配式热电阻无法安装 的场合 Armored thermal resistance is a type of temperature sensor, which has a smaller diameter than assembled platinum resistance , is easy to bend, has good shock resistance, and is suitable for installation where assembled thermal resistance cannot be installed .

     的外保护套采用 的是 不锈钢 材质 ,里面充满了高密度氧化物质绝缘体,因此,它具有很强的抗污染性能和优良的机械强度,并且适合安装在环境恶劣的场合 The outer protective sheath of the armored thermal resistor is made of stainless steel , which is filled with high-density oxidant insulators. Therefore, it has strong anti-pollution performance and excellent mechanical strength, and is suitable for installation in harsh environments . 温度,还可以直接用铜导线和二次仪表相连使用 Armored thermal resistors can be used to measure temperatures in the range of -200 to 500 ° C. They can also be directly connected to secondary meters using copper wires . 记录仪 调节仪 扫描器 数据记录仪以及电脑提供精确的温度变化输入信号 Because of its good electrical output characteristics, it can also provide accurate temperature change input signals for displays , recorders , regulators , scanners , data loggers, and computers .
Second working principle
     工作原理:在温度作用下热电阻丝的电阻 着温度的 变化而变化 Working principle of armored thermal resistance : The resistance of the thermal resistance wire will change with temperature under the action of temperature . 示出热电阻产生的电阻值所对应的温度值 The display meter will display the temperature value corresponding to the resistance value generated by the thermal resistance .
