1. The resistance of different types of NTC temperature sensor is different, but how to judge the quality of the temperature sensor? Very simple, it is to measure its voltage online, the normal voltage at 25 degrees is generally between + 2 ~ + 2.5V .
2. Because the human body temperature is constant, the on-circuit voltage is not constant (approximately 2.17V) when holding the temperature-sensing head for a while.
3. Unplug the NTC temperature-sensing head, and measure the resistance of the two pins of the socket on the line. The resistance value is basically the model value of the temperature-sensing head at 25 ℃ (this method is inaccurate after actual inspection). If the resistance is about 8K, the model value of the NTC sensor temperature head is generally 10K; if it is a 4.7K resistance, it is a 5K temperature head; and so on. Dock, for some large air conditioners, the resistance value of the NTC temperature sensor of the control board of the inverter air conditioner external unit is 3 times the lower bias resistance, som är, the resistance value measured by the above method multiplied by 3 is the resistance value of the NTC sensor at 25 °C.
4. The model value of the NTC temperature sensor is its resistance value at 25 ℃, usually 5K, 10K, 15K, 20K, 25k, 50K, 100K which are generally negative temperature coefficient, som är, ju högre temperatur, the more the resistance value small.
5. I stort sett, the temperature of the internal machine tube and the room temperature resistance are the same.
