Stainless Steel NTC Thermistor Probe B3950 10K in water dispenser

The NTC temperature sensor 1% B3950 10K, 5 x 25mm with XH2.54 Connector in a water dispenser is a device used to measure the temperature of water. This sensor is usually a temperature sensor that converts the temperature information of the water into an electrical signal. Here are some types of temperature sensors that may be used in water dispensers:
These NTC temperature sensor 10K, 15K, 20K, 50K probe types can vary depending on the design of the water dispenser and the manufacturer’s choice. The accuracy, response speed and stability of the sensor are critical to the performance of the water dispenser, so manufacturers usually choose the appropriate sensor type for a specific application.

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. しかし, 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, あれは, the resistance value measured by the above method multiplied by 3 is the resistance value of the NTC sensor at 25 ℃.

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, あれは, the higher the temperature, the more the resistance value small.

5. 一般的に言えば, the temperature of the internal machine tube and the room temperature resistance are the same.
