A Thermocouple with a SS310 Sheath and Aluminium Head is a specialized, high-temperature industrial sensor assembly chosen primarily for its exceptional resistance to high-temperature oxidation and scaling.
This assembly is specified for applications where temperatures regularly exceed the practical limits of more common stainless-steel grades like SS304 and SS316.
1. Thermocouple Element
• Function: The internal element (which could be Type K, N, R, or S, depending on the required temperature range) measures the heat and converts it into a minute electrical signal mV.
2. SS310 Sheath
• Material: Stainless Steel Grade 310 (SS310). This is a high-chromium and high-nickel austenitic stainless steel.
• Key Advantage (High Temperature): The significantly higher chromium content (approx. 24-26%) and nickel content make SS310 the core feature of this assembly. This composition provides:
• Excellent Oxidation Resistance: It forms a stable, protective oxide layer even in continuously high temperatures 1150°C, preventing the sheath from rapidly scaling, flaking, or degrading.
• Creep Resistance: It maintains its mechanical strength and resists deformation (creep) better than lower-grade stainless steels at elevated temperatures.
• Applications: It is essential for use in furnaces, kilns, heat treatment ovens, fluidized beds, and high-temperature exhaust systems where extreme heat and oxidizing environments would quickly destroy SS304 or SS316.
3. Aluminium Head
• Design and Function: This is the robust, protective enclosure located at the cool end of the sensor.
•Material: Aluminium is lightweight, corrosion-resistant, and dissipates heat effectively. Since the head is positioned away from the direct high heat, aluminium is suitable for protecting the sensitive electronics and connections.

A temperature sensor is a device that gathers information about the thermal energy (heat) of a medium and converts that information into a readable electrical signal. Essentially, it measures heat and outputs a corresponding signal (voltage, current, or resistance) that can be interpreted by a control system or thermometer.
The three most widely used types of temperature sensors are:
The temperature reading needs to be converted into an electrical signal (like a voltage or current) so it can be:
Temperature sensing is foundational to industrial control and everyday technology:
