(6) Matters needing attention:
Welding method: The metal body and the body are directly welded for welding. Do not use soldering to avoid false welding. The welding time is controlled within 3.5 seconds
Do not test the enameled wire thermistor in the air. The temperature difference in the air is large, and the measurement is very inaccurate. It often produces a deviation of more than 1-2°C. It must be measured with a high-precision constant temperature oil tank, and the measured NTC is placed in the constant temperature oil tank. After that, the temperature of the constant temperature bath must be stable before
NTC Type Thermistor is a high-quality MF5 Single-ended glass sealed thermistor, which is designed for temperature measuring applications. It provides an accurate temperature sensing solution with resistance range from 1KΩ to 500KΩ, operating temperature range from -55°C to +125°C and rated power up to 50mW. The axial leaded shape of this thermistor results in a very low dissipation factor of 22mW/C, even under still air condition. It is also designed with MF52 temperature measuring thermistor, which makes it an ideal choice for temperature measurement applications.
