0.10mm~3.2mm Ni-Cr-Si (NP) Ni-Si-Magnesium (NN) Type N Thermocouple Bare Wire For Temperature Sensor

Introduction:

Type N thermocouple bare wire is a type of thermocouple commonly used for temperature measurement and control. It is composed of nickel-chromium-silicon alloy (Nicrosil) and nickel-silicon-nickel-aluminum alloy (Nisil). Type N thermocouple bare wire is suitable for higher temperature ranges, typically measuring temperatures from -200°C to 1,300°C. This type of thermocouple has good linear characteristics and oxidation resistance, and can provide accurate and reliable temperature measurements. N-type thermocouple bare wire has wide application prospects in high-temperature industrial fields, such as metallurgy, glass manufacturing, chemical reactor monitoring in the chemical industry, and temperature measurement of high-temperature experimental devices in scientific research and laboratories. Its advantages include high-temperature measurement capabilities, corrosion resistance and fast response.
