What Is Magnesium Oxide Powder?
Meaning of MGO
Magnesium oxide powder (MGO powder) is a white powdered mineral that is a source of magnesium. It is also called Magnesia or MgO.
What is Magnesium Oxide used for?
Magnesium oxide powder is widely used as an insulation material in temperature sensors, particularly mineral-insulated thermocouples. It is tightly packed inside the sensor sheath to:
- Provide electrical insulation for sensor wires.
- Protect the wires from mechanical damage.
- Enable the sensor to withstand very high temperatures.
MgO powder has become the standard insulation material for high-temperature sensors due to its excellent thermal and electrical properties.
Ensure Reliability with Quality Magnesium Oxide Insulation
Magnesium oxide powder is essential for durable, high-temperature sensor insulation. Our MI thermocouples and RTDs use premium MgO powder to deliver precise, long-lasting performance in demanding environments.
