Cặp nhiệt điện AEROPAK Mineral Insulated Thermocouple - Okazaki Vietnam

EROPAK is a trademark of our metal sheathed thermocouples. AEROPAK, a sheathed thermocouple, is a thin tube (sheath) made of stainless steel or heat-resistant steel, thermocouple wires enclosed within the tube and inorganic insulator (MgO) firmly packed around the wires. We manufacture various products based on this structure according to purposes of use. In comparison to general protection tube type thermocouples, sheathed thermocouples have many excellent features.

Principle of Thermocouples

A thermocouple consists of two metal wires whose types differ from each other with both ends connected and when a temperature difference occurs at the contacts of both ends, thermo-electromotive force occurs and current flows within this closed circuit. The amount and the polarity of this thermo-electromotive force depend on the temperature of both ends and the combination of two metal wires and is not influenced by the thickness and length of the metal wires. Therefore, if you know the thermo-electromotive force at each temperature of specific thermocouples beforehand, you can measure the temperature.

Features

In comparison to conventional Protection Tube type thermocouples, AEROPAK has the following features.

• １．Wider Application Range

  Since the outer diameter is small, you can measure the temperature of small targets. In addition, since the structure is a sheath type, AEROPAK is high temperature/high pressure tolerant and can be used for a wide temperature range of -200 to 1,260℃.

• ２．High Response

  Since a thermocouple with a smaller outer diameter has smaller heat capacity, AEROPAK sensitively responds to temperature changes.

• ３．Easier Handling

  The minimum bend radius is two times larger than the sheath outer diameter. AEROPAK easily installed in various places at a site.

• ４．Longer Product Life

  In comparison to conventional thermocouples, AEROPAK has a longer life since it is insulated and sealed with magnesium oxide which is stable chemically for thermo-electromotive force deterioration and accidents of disconnection, etc.

• ５．Mechanical Strength/Pressure Resistance

  Selecting sheath materials allows safe use even in places with high vibration, corrosive atmosphere, high temperature and low temperature. Even a sheath with a small outer diameter allows approx. 350 MPa of pressure resistance strength at 650℃.

• ６．Sheath Outer Diameter Manufacturing Available

  We can manufacture a sheath outer diameter of 0.08 to 22 mm.

• ７．Sheath Length Manufacturing Available

  We can manufacture up to approx. 1,000 m depending on the sheath outer diameter.

• ８．Special Needs Handling

  We can handle various needs with our factory dedicated to sheaths.
