10k thermistor resistance chart

Thermistors are manufactured to follow a specific curve with a high degree of accuracy. A 10K thermistor, however, will only restrict 10,000 ohms of a current at 25℃. 3k 10kType 10kType 10kDale 10k3A210kG US 20k. It follows a pre-defined curve which is provided by the thermistor manufacturer. They are used for resistance thermometers in temperature measurement and all Sterling Sensors assemblies are made using this type of thermistor. 0000003089 00000 n Therefore thermistors can have the same reference resistance of 10,000 Ω at 25 Deg C (R25) but can have different B values, so both values are needed to identify a thermistor. negative B - 10K4A1 Sensor type: Thermistor, temp coef. 0000001890 00000 n 2)The register of value 470*10^6 Ω+- 20% will have the colour code yellow, violet, black, blue and 5th band will be absent. To test the device a 10K ohn resistor can be plugged in in-place of the thermistor cable and the device should read it as 77F (25C) degrees. The beta constant for the thermistor is 3380, the thermistor resistance (R0) at 25°C is 10K ohms, and the ADC returns a value 366. 0000013732 00000 n PN 1600-10K Thermistor Thermistor Resistance vs Temperature Chart The enclosed negative temperature coefficient (NTC) thermistor, pn 1600-10K. of Teflon encased thermistors add 100 to part No. In the standard Steinhart-Hart equation the C parameter is set to zero. The major difference between the RTD and the Thermistor is that the RTD is made of metal, whereas the semiconductor material is used for Thermistor. 0000054410 00000 n 0000054866 00000 n 6 54 Note: Only thermistors with ±0.2°C interchangeability are available encased in Teflon as standard parts. P/N 1600-10K Thermistor The enclosed negative temperature coefficient (NTC) thermistor, p/n 1600-10K, works by translating temperature into resistance, with resistance decreasing as temperature increases (hence the ‘negative coefficient’). It is important to note that a thermistor’s change in resistance is non-linear. The data from the tests shown below 0 thermistor’s change in resistance is non-linear.

The term thermistor is a contraction of the words "thermal" and "resistor". Thermistor resistance is related to temperature in degrees Kelvin by the following formula: 1/T= A + B*ln(R/Rt) + C*ln(R/Rt) 2 + D*ln(R/Rt) 3.
