Product Applications

Thermocouple Connections: MI cables are commonly used to connect thermocouples to temperature measurement devices in applications such as furnaces, kilns, and chemical processing plants.

Instrumentation: Suitable for connecting various instruments in process control systems, including pressure, flow, and level sensors.

Oil and Gas Industry: Employed in drilling operations, pipelines, and refineries to monitor temperatures in extreme environments.

Power Generation: Used in turbines, boilers, and other critical components where precise temperature measurement is essential for safety and efficiency.

HVAC Systems: Applied in heating, ventilation, and air conditioning systems for accurate temperature monitoring and control.

Installation Considerations:
  • Bending Radius: MI cables have a specified minimum bending radius that should be adhered to during installation to avoid damaging the insulation.
  • Termination Techniques: Proper crimping or welding techniques should be used to ensure reliable electrical connections at the thermocouple junctions.
  • Environmental Factors: Consideration of factors such as temperature, pressure, and chemical exposure is critical during the selection and installation of MI cables.
Common Applications:
  • Solid waste incinerators
  • Sintering powdered metals
  • Firing ceramic materials
  • Gas or oil fired furnaces
  • Fuel fired heat exchangers
  • Box furnaces
  • Nuclear or hydrocarbon based energy plants
