Maltec-T MI Thermocouple With Pot Seal & Flexible Tails


  • Inexpensive termination
  • Will withstand tough industrial use

Dpstar provides Top Thermocouple Solutions with High-Quality Assurance. We’ve made mineral insulated thermocouples for over 30 years and today we are considered the best choice for custom-built temperature sensors in Malaysia. We continue to apply our expertise and invest in the latest technology to provide our customers with the highest quality temperature sensors available. If you have an existing sensor design or are unsure what you need we’ll be able to find you to get the right sensor for your process.

Mineral insulated thermocouples consist of an outer metal sheath which protects the thermocouple elements from damage and contamination, this sheath is malleable so mineral insulated thermocouples can be easily bent and formed into a variety of shapes to suit your application. The inner thermocouple elements are insulated with magnesium oxide powder, tightly packed so no air is trapped inside, this provides great thermal conductivity. This construction provides an incredibly durable temperature sensor that can be adapted to a wide variety of applications.

Maltec-T MI Thermocouple With Pot Seal & Flexible Tails is a very common robust sensor with a wide range of applications. One of our most popular designs of thermocouple. Can also be known as a “bare leads” MI thermocouple.

Wide Variety in Designs and Uses

MI Thermocouples are very tough and can withstand up to 1250°C (depending on design and thermocouple type) making them perfect for a wide variety of industrial uses such as ovens, kilns, and furnaces. There is a wide range of options for our MI thermocouples. They can be constructed with various diameters and materials of the sheath, many different thermocouple types, and with our laser welder, mineral insulated thermocouple lengths are practically limitless.
