The Model 2A Thermocouple Sensorube cosists of aube cotaininga filamenheated byhe passage of a costancue. Athermocouple is weldedohe ceer ofhis heated elemeherebyproviding a means of directly measuringhe elemeemperature ierms of voltage output. For any costanvalue of cuehroughthe filame,heemperature ofhe filamenincreases ashepressure itheube iseduced. Thehermocouple voltage isdirectly proportioalohe increasedemperature ofhe filame,andhus generates aincrease ivoltage. Sensitive circuitryincludeshehermocouple outpudirectly imicrons. The standardsensorube hasickel-plated, forged-brass housing which makes itcapable of withstanding 150 psi overpressure. Allhermocoupleelemes are preoxidized under cotrolled coditionso provideierchangeability ofubes withoutecalibration. This processalso provides high stability and minimizeshe effecofcoamination. Stainless steel versions are available.

型号A热电偶传感器的管组成的管包含由通过一个恒定的电流加热的灯丝。一个热电偶被焊接到该加热元件，从而提供了一种手段，直接测量在电压输出的元件温度的中心。对于任何恒定值的电流通过灯丝，灯丝的温度增加，作为在管内的压力被减小。热电偶电压直接正比于灯丝的温度增加，从而产生一个增加的电压。敏感的电路，包括热电偶直接输出微米。标准传感器管镀镍，锻造黄铜外壳的，这使得它能够承受150psi的压。所有热电偶元件的负压控制的条件下，以提供互换管，而无需重新校准。这个过程还提供了高稳定性，并**限度地减少了污染的效果。不锈钢版本可供选择。
