Sheathed Thermocouples - 1

SHEATHED THERMOCOUPLES A metallic sheath and a detection element are assembled in each sheathed temperature sensor. The clearance between the sheath and the thermocouple wire is tightly filled with magnesium oxide or another inorganic insulator to keep the insulation, and the interior to keep the insulation, and the interior is kept airtight to prevent the sensor from being corroded by air and hot gases. The features of these sensors are as introduced below. FEATURES Long life and economical Very high sensitivity and little time delay Excellent vibration resistance Employable under hot, high-pressure, corrosive gas atmosphere, and other unfavorable conditions Freely bendable and mountable at a frequent curved position. Since the minimum outer diameter of sheathed thermocouples is as thin as 0.15mm, these sensors can detect temperature of a small measuring substance at a narrow place where the temperature measurement has conventionally been impossible.
