Common sense of platinum thermal resistance
2011-8-20 9:55:09

  

    一样和 使用温度的不 一样 形成的 铂热电阻 按照绕制的 材料 区分,有云母 陶瓷 簿膜等元件。 According to the difference in the use situation and the use temperature , the platinum thermal resistance formed is divided according to the wound material , and there are elements such as mica , ceramics , and film. 可以将 精确的输入值提供 显示仪 记录仪 调节仪以及其它 类似 “电脑” 仪表 The temperature measuring element has good output performance, and can provide accurate input values to display instruments , recorders , regulators and other instruments such as "computers" . 配接 的是 一体化温度变送器 ,可输出4 - 20mA和0 - 10V等标准电流和电压信号,使用更 加的 方便。 If the integrated temperature transmitter is connected , it can output standard current and voltage signals such as 4-20mA and 0-10V, which is more convenient to use.
可以 组成装配式热电阻 Temperature sensing elements, stainless steel protection tubes, junction boxes, and fixtures for various uses can form assembled thermal resistors .
装配式铂热电阻 相比:( 1) 直径小 2) 易弯曲 3) 适宜安装在装配式无法安装的场合 4) 外保护管采用不锈钢 Comparing armored platinum thermal resistance with assembled platinum thermal resistance : ( 1) small diameter ( 2) easy to bend ( 3) suitable for installation where assembly cannot be installed ( 4) the outer protective tube is made of stainless steel . 内充满高密度氧化物质绝缘体 因此它具有很强的抗污染和优良的机械强度,能在环境较为恶劣的场合使用。 Because the armored thermocouple is filled with high-density oxidant insulators , it has strong anti-pollution and excellent mechanical strength, and can be used in harsh environments.
伴有各种易燃 易爆等化学气体 或者 蒸气场合 生产现场 中,不能 使用普通铂热电阻 ,因为普通的容易 引起环境气体爆炸,因此在这种场合必须使用爆式的铂热电阻 Generally, in the production site accompanied by various flammable , explosive and other chemical gases or vapors , ordinary platinum thermistors cannot be used , because ordinary gas is easy to cause ambient gas explosion, so explosion - proof platinum must be used in this occasion . Thermal resistance .
