NiCrSi-NiSiMg Type N Thermocouple Extension Wire The Preferred Solution For Industrial Temperature Sensing

NiCrSi-NiSiMg Type N Thermocouple Extension Wire is a high-performance extension wire used in conjunction with Type N thermocouples for temperature measurement applications. It is composed of a positive leg made of nickel-chromium-silicon (NiCrSi) and a negative leg made of nickel-silicon-magnesium (NiSiMg). This wire is designed to extend the length of the thermocouple without compromising the accuracy of temperature readings.

Key features of Type N Extension Wire include its ability to operate within a wide temperature range of -200°C to 1300°C, making it suitable for extreme temperature environments. It offers superior oxidation resistance due to the protective diffusion barrier formed by chromium and silicon in the positive leg and silicon and magnesium in the negative leg. The wire also provides improved repeatability and magnetic stability, which is crucial for accurate temperature measurement.

Type N Extension Wire is used in various industrial applications, including furnaces, boilers, and chemical processing equipment, where reliable temperature monitoring is essential. It is manufactured to meet international standards, ensuring quality and reliability. The extension wire is designed to match the thermoelectric properties of the thermocouple, ensuring that the signal from the sensing element is transmitted accurately to the measuring or control device.

Thermocouple temperature range and tolerance

Some key features of NiCrSi-NiSiMg Type N Thermocouple Compensating & Extension Wire include:

• Superior Oxidation Resistance:

The Type N thermocouple wire, with its higher levels of chromium and silicon in the positive Nicrosil conductor, offers improved oxidation resistance compared to other types.

• Wider Temperature Range:

It can operate within a broad temperature range of -200°C to 1300°C, making it suitable for a variety of high-temperature applications.

• Improved Repeatability:

Type N thermocouples show much improved repeatability in the 300°C to 500°C range, where other types like Type K may exhibit instability.

Magnetic Stability: The high levels of chromium in the NP conductor and silicon in the NN conductor provide improved magnetic stability.

• Longevity:

Type N thermocouples have a longer operational life than Type K thermocouples, with reduced EMF drift and short-term EMF changes.

• Resistance to Transmutation:

The absence of manganese, aluminium, and copper in the NN conductor makes Type N thermocouples more stable against nuclear bombardment, virtually eliminating the risk of transmutation.

• Standard Compliance:

Manufactured to meet international standards, ensuring quality and reliability.

• Extension Wire:

The extension wire for Type N thermocouples is designed to match the thermoelectric properties of the thermocouple over a certain temperature range, typically from -25°C to 200°C, and is used to extend the range of the thermocouple without significantly affecting its accuracy.

These features make NiCrSi-NiSiMg Type N Thermocouple Extension Wire an ideal choice for precise temperature measurement and control in various industrial applications.
