Mineral Insulated Metal Sheathed Thermocouple Cable is used to insulate thermocouple wires from one another and from the metal sheath that surrounds them. The simplex MI Cable has two thermocouple wires running down the middle of the tube. The tube is then filled with magnesium oxide powder and compacted to ensure the wires are properly insulated and separated. MI cable helps to protect the thermocouple wire from corrosion and electrical interference.
Feature:
Waterproof: The mineral insulated metallic sheath and special IP67 waterproof fittings prevent the penetration of water, and dust towards the cores. The Mineral insulated cables are also suitable for outdoor applications or for installation under concrete if properly protected against Eddy current.
Fireproof: MI cable can withstand very high temperatures (higher than 1000°C), since all its components are inorganic. It can go on working during a fire, maintaining power to all emergency services, allowing all safety and protection measures within the building to be activated.
Mechanical strength: The metallic sheath acts as a protective screen, and therefore Mineral insulated cables can withstand extremely high mechanical stress such as crushing and curvature with a bending radius equal to 6 times the diameter of the cable.
