Versatile Sensing for Industrial Applications

These MI thermocouples are designed for rigorous industrial temperature sensing tasks, thanks to their robust construction, various sheath diameters, and high-performance materials. They withstand harsh conditions, allowing for accurate thermal energy measurement and monitoring in diverse manufacturing environments, refineries, and process plants.

Precision Meets Durability

Our thermocouples adhere to international standards, delivering Class 1 accuracy (up to 1.5C) and rapid response (3 seconds). Their insulation resistance over 1000 M and quality sheath materials (SS304, SS316, Inconel 600) ensure consistent, reliable readings, even in challenging environments or at high process temperatures.

FAQs of Mineral Insulated Thermocouple:

Q: How is a mineral insulated thermocouple installed in industrial applications?

A: Mineral insulated thermocouples can be mounted as probe/immersion, surface, or custom mount types. Installation depends on process requirements; typically, the sensor is inserted into a thermowell or directly into the process medium, ensuring the minimum bend radius of 2x sheath diameter is maintained to avoid damage.

Q: What are the benefits of using mineral insulated thermocouples for temperature measurement?

A: MI thermocouples offer fast response times (3 seconds), robust mechanical strength, flexibility in mounting, and high insulation resistance. Their design allows accurate and reliable temperature readings in demanding environments, minimizing downtime and enhancing process control.

Q: When should I choose SS304, SS316, or Inconel 600 sheath material for a thermocouple?

A: The choice of sheath material depends on your process environment. SS304 suits general industrial conditions, SS316 offers enhanced corrosion resistance, and Inconel 600 is ideal for high-temperature or highly corrosive settings. Material selection ensures sensor longevity and measurement reliability.

Q: Where can mineral insulated thermocouples be used?

A: These thermocouples are widely used in manufacturing, petrochemical plants, power generation, pharmaceuticals, and research laboratories across India. Their robust construction allows installation in both harsh and standard environments for continuous temperature monitoring.

Q: What process ensures high insulation resistance in MI thermocouples?

A: The mineral insulation, typically compacted magnesium oxide (MgO), is tightly packed around the thermocouple wires inside the sheath. This design provides reliable insulation, resulting in resistance greater than 1000 M at 500V DC at room temperature, ensuring measurement integrity.

Q: How does an MI thermocouple function as a passive device?

A: MI thermocouples generate a voltage proportional to the temperature difference between the measuring and reference junctions. As passive sensors, they do not require external power; they interface directly with indicators, controllers, or transmitters for temperature readout.
