The Model 2A Thermocouple Sensor tube consists of a tube containinga filament heated by the passage of a constant current. Athermocouple is welded to the center of this heated element therebyproviding a means of directly measuring the element temperature interms of voltage output. For any constant value of current throughthe filament, the temperature of the filament increases as thepressure in the tube is reduced. The thermocouple voltage isdirectly proportional to the increased temperature of the filament,and thus generates an increase in voltage. Sensitive circuitryincludes the thermocouple output directly in microns. The standardsensor tube has nickel-plated, forged-brass housing which makes itcapable of withstanding 150 psi overpressure. All thermocoupleelements are preoxidized under controlled conditions to provideinterchangeability of tubes without recalibration. This processalso provides high stability and minimizes the effect ofcontamination. 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。
