2.252KΩ±0.1℃ B25/50=3935K PI Probe NTC Temperature Sensor
Product Description:
1. Resistance: 2.252KΩ (2.252 kiloohms) - This value represents the nominal resistance of the NTC thermistor at a specific temperature (usually 25°C).
2. Tolerance: ±0.1℃ - This indicates the accuracy of the temperature measurement with the sensor. The sensor's temperature readings may have a maximum deviation of 0.1 degrees Celsius from the actual temperature.
3. B25/50: 3935K - The B25/50 value represents the Beta value (B) of the NTC thermistor. It is used to determine the temperature coefficient of the thermistor. In this case, it suggests that the sensor's Beta value is 3935 Kelvin.
The Beta value is an important parameter for NTC thermistors as it helps convert the sensor's resistance into temperature. The Steinhart-Hart equation is commonly used for this purpose:
where:
T is the temperature in Kelvin,
A, B, and C are the Steinhart-Hart coefficients for the specific NTC thermistor,
R is the resistance of the thermistor at the current temperature,
R0 is the nominal resistance of the thermistor at a reference temperature (usually 25°C).
PI Probe: Polyimide probe
Overall, this NTC temperature sensor can measure temperature accurately with a resistance of 2.252 kiloohms at 25°C, using a B25/50 value of 3935K to calculate temperature variations based on changes in resistance. Keep in mind that specific calibration and circuitry are required to convert the resistance readings to accurate temperature values.
