Product Description
B3950 10K NTC Thermistor Temperature Sensor 5*25mm
This sensor is a high-precision, waterproof B3950 10K NTC thermistor temperature sensor with a stainless steel 5 x 25mm tip and an XH2.54 connector. It has a 5-meter cable and can measure temperature in various applications.
The sensor has a negative thermal coefficient (NTC), which means its resistance decreases as the temperature increases. However, the relationship between resistance and temperature is not linear, so it is better to use a table of measurements than a linear formula. The table of measurements can be found in the datasheet that comes with the sensor.
