Koaksiaalilämpöparianturit

Koaksiaalilämpöparianturit, known in English as coaxial thermocouples, are a type of temperature sensor designed for measuring temperatures within confined spaces or along the axis of cylindrical objects. Their construction involves a thermocouple junction placed at the center of a hollow, typically metallic, coaxial structure. This structure consists of an inner conductor and an outer sheath, with the thermocouple wires running through the central opening.

The primary advantage of koaksiaalilämpöparianturit is their ability to provide localized temperature readings with minimal disturbance to the surrounding environment. The coaxial design ensures that the thermocouple junction is well-protected and can be inserted deeply into a system without significantly altering its thermal properties or flow characteristics. This makes them suitable for applications such as measuring temperatures in pipes, nozzles, or within the cores of machinery.

These sensors are often used in industries where precise temperature control in restricted areas is crucial, including aerospace, automotive, and industrial manufacturing. The materials used for the outer sheath and inner conductor are selected based on the operating temperature range and the chemical environment to ensure durability and accuracy. They can be fabricated with various thermocouple types, such as Type K, J, or T, depending on the required temperature range and sensitivity. The response time of a koaksiaalilämpöparianturi can vary depending on the specific design and the thermal conductivity of the surrounding materials.
