MgO sheathed thermocouples utilize magnesium oxide (MgO) as insulation within a metal sheath, resulting in a robust, flexible, and durable sensor with fast response time and high accuracy. This construction protects the thermocouple wires from high temperatures, pressure, vibration, corrosion, and mechanical impact, making them suitable for use in various industrial, medical, and research environments, even in hard-to-reach locations.

Why MgO in the sheathing?

High temperature resistance:

MgO is an excellent fire-resistant insulation material that protects the thermal wires at high temperatures.

The compact, pressed MgO provides good insulation between the thermal wires and the metal sheathing, while ensuring efficient heat transfer to the measuring point. This results in fast response times, crucial for accurate temperature measurements.

Protection and durability:

The metal sheath, insulated by MgO, protects the thermal wires from mechanical damage, vibration, corrosion, and aggressive chemicals.

Flexibility and flexible bending: The thin sheathed wire is flexible, allowing these sensors to be used in inaccessible locations.

Protection: The sheath protects the measuring point from oxidation and contamination, improving the sensor's lifespan and accuracy. Fast response: The efficient heat transfer through the MgO material ensures a fast response time, allowing temperature fluctuations to be quickly detected. Versatility: Sheathed thermocouples are available in various types (such as K,N, T, J, and S,B etc), diameters, and lengths, making them widely applicable in various applications, from food processing to power generation.
