If the thermistor is NTC type then it decreases the resistance as increase in temperature and PTC behavior is just opposite to the NTC. °C Rt/R25 TEMP. Specifications:. 15 o C) and some can be used above 150 o C. An example of a thermistor output curve can be seen in Figure 1. 03) = 17,951 ohms Once you calculate the value for Rt, you can use a look-up table containing temperature-resistance data for your thermistor to find the corresponding temperature. I know they are in the 10k range. Elchoroukhost. Note: "Beta" Value 3950. (R25°C = 10KZ±3% - B25/85°C = 3975K±1. A lookup table is a convenient way to convert a thermistor’s ADC reading to temperature. Beta (K) 3890. It is recommended to duplicate the existing thermistor table and comment the duplicated copy out - in case reverting to original values is needed. A thermistor’s resistance varies with temperature. It follows a pre-defined curve which is provided by the thermistor manufacturer. The bottom half of the voltage divider is a 10k Ohm 3% NTC thermistor.

Find 10k NTC Temperature Sensors related suppliers, manufacturers, products and specifications on GlobalSpec - a trusted source of 10k NTC Temperature Sensors information. The figure below shows the characteristic curve of a NTC thermistor:. Temperature vs resistance chart for 10K ohm NTC Type II thermistor. I need to generate a look up table to convert fron the 14bit ADC value to converd to a Centigrade display read out MSP430P325AISP. A Free & Open Forum For Electronics Enthusiasts & Professionals Are these standard values for a 10k NTC thermistor or how can I find these? so NTC temperature sensor should give similar temperature when look up table will be used on MPU based on. Consult the thermistor manufacturer documentation for accurate values. Then I ended up moving to 1Wire temperature sensors, which don't require a table and are very precise. Figure 15 NTC used to control PWM as a function of temperature Another option is shown in Figure 16. 18, 2018 NTC thermistors: Robust temperature sensor for up to 300 °C Apr. The one that I purchased has a resistance of 10k at temperature of 25 degree Celsius and the resistance go up when temperature go down. To convert the measured resistance to temperature, you can use a chart, or a portion of it, as a lookup table in your software and interpolate between adjacent degrees, or you can use an. A Negative Temperature Coefficient (NTC) thermistor decreases in resistance as its body temperature increases. Resistance @ 25°C = 10K˜ B25/50 =3950K T(°C) R(KΩ) T(°C) R(KΩ) T(°C) R(KΩ) T(°C) R(KΩ) T(°C) R(KΩ) T(°C) R(KΩ)-40 277. A 10K ohm resistor 9.
