    • An aspirating or suction pyrometer for measuring hot combustion gases. A thermocouple in the pyrometer has a temperature sensitive junction formed of platinum alloys. The thermocouple junction is insulated and is encased within a platinum alloy sheath. The sheathed thermocouple is mounted within inner and outer tubular radiation shields. These shields are formed of a platinum alloy having a radiation emissivity substantially the same as the thermocouple. The shields block radiated heat from the flame and combustion chamber from being transferred to the thermocouple. The radiation shields do not themselves radiate heat to the thermocouple because the shields and thermocouple are at the same temperature and formed of substantially the same noble alloys.
    • 用于测量热燃气的吸气或吸气高温计。 高温计中的热电偶具有由铂合金形成的温度敏感结。 热电偶接头是绝缘的,并被封装在铂合金护套内。 护套热电偶安装在内部和外部管状辐射屏蔽内。 这些屏蔽由具有与热电偶基本相同的辐射辐射率的铂合金形成。 屏蔽块将来自火焰和燃烧室的辐射热量传递到热电偶。 辐射屏蔽本身不会向热电偶辐射热量,因为屏蔽和热电偶处于相同的温度并由大体上相同的贵金属合金形成。

    • A stand-alone thermostat that mounts flush to a wall and obtains improved accuracy in ambient temperature measurement by actively intaking air from the room interior. An internal temperature measurement chamber communicates between air inlet and outlet. A heat generator located within the temperature measurement chamber causes thermal convection, the convection generating an air flow thus drawing ambient room air into the measurement chamber, across a temperature sensor, and out the outlet air opening. This feature assures that the temperature of room interior air is accurately measured.
    • 一个独立的恒温器,通过积极吸入室内空气,将其齐平地安装在墙壁上,从而提高环境温度测量的精度。 内部温度测量室在空气入口和出口之间连通。 位于温度测量室内的热发生器引起热对流,对流产生空气流,从而将环境室内空气通过温度传感器吸入测量室,并从出口空气开口排出。 该特征确保室内空气的温度被精确测量。
