Mineral insulated RTD cables are used in combination with a thin film or wirewound ceramic resistor Pt100 element. The principle of an RTD is that resistance value changes as its temperature changes. RTD pt100 sensors are used to measure temperatures extremely accurate in a certain set temperature range. This range can vary from -200° C to + 850° C. Since the resistors are very delicate, they are often placed in a mineral insulated RTD cable to ensure protection and stability.
Kamet has a large stock of Okazaki mineral insulated RTD cable.
We have an extensive stock (over 200KM) of Okazaki AerOpak® mineral insulated RTD-cable in our warehouse. The Copper, Copper-Nickel, Nickel, nickel-chromium or Constantan alloys in the MI cable provide a stable transmission of the signal and our two different designs (wide-spaced and regular spaced) guarantee efficient mounting for either method. Our mineral insulated RTD cables are typically sheathed with material varying from Inconel to different types of stainless steel.
Mineral insulated RTD cable with constantan conductors is a perfect choice for temperature measurements up to 650°C.
Copper conductors have a very stable resistance vs temperature relation
Inconel 600 (2.3816) conductors have a high corrosion resistance
Due to its higher annealing temperature, RTD cable with nickel conductors can be used at high temperatures.
Our AerOpak® mineral insulated RTD cables have 2 designs of spacing: wide-spaced (A) and normal (J) spaced conductors. The difference between the two designs is the inner-circle diameter. This allows manufacturers to use different ways of mounting the RTD-element to the inner conductors.
The thinfilm or ceramic wirewound Pt100 or Pt1000 resistors are usually welded to the inner conductors of a mineral insulated RTD cable. Since the bending process is of mineral insulated RTD cables is easy, the sensor is easily installable at sites with many bends.
Every single coil of each batch MI cable, manufactured by Okazaki is calibrated to ensure IEC60584-2 class 1, ASTM E230 special limits or AMS2750 E/F. Traceability is assured on every AerOpak® MI cable Kamet has in stock.
To enable our customers decoding the product description, we have created a decipher tool. This tool makes it easier to comprehend the product descriptions of the mineral insulated thermocouple cable. Check our brochure for more information.
Okazaki has over 60 years of experience in producing mineral insulated thermocouple cable. Besides mineral insulated thermocouple cable, Okazaki also manufactures mineral insulated RTD cables. The mineral insulated RTD cable that Okazaki produces goes under the same trademark as the mineral insulated thermocouple cables: AerOpak®.
The most accurate way to measure temperature is by using a Resistance Temperature Detector (RTD). However, the temperature range of an RTD is limited compared to a thermocouple.

This depends mainly on the temperature range and accuracy. Furthermore, it also depends on other variables, such as costs, ruggedness of the application, vibration resistance, etc.
