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.

型號A熱電偶傳感器的管組成的管包含由通過一個(gè)恒定的電流加熱的燈絲。一個(gè)熱電偶被焊接到該加熱元件，從而提供了一種手段，直接測量在電壓輸出的元件溫度的中心。對于任何恒定值的電流通過燈絲，燈絲的溫度增加，作為在管內(nèi)的壓力被減小。熱電偶電壓直接正比于燈絲的溫度增加，從而產(chǎn)生一個(gè)增加的電壓。敏感的電路，包括熱電偶直接輸出微米。標(biāo)準(zhǔn)傳感器管鍍鎳，鍛造黃銅外殼的，這使得它能夠承受150psi的壓。所有熱電偶元件的負(fù)壓控制的條件下，以提供互換管，而無需重新校準(zhǔn)。這個(gè)過程還提供了高穩(wěn)定性，并**限度地減少了污染的效果。不銹鋼版本可供選擇。
