Thermistor Resistance Chart

Thermistor Resistance Chart - The term thermistor is a contraction of the words thermal and resistor. 44005 is a standard thermistor. They are used for resistance thermometers in temperature measurement and all sterling sensors assemblies are made using this type of thermistor. Web an ntc thermistor is a thermally sensitive resistor for which the resistance exhibits a large, precise and predictable decrease as the core temperature of the resistor increases over the operating temperature range. They are often used as a temperature sensor. So for example, 2k2ω at 25 o c, 10kω at 25 o c or 47kω at 25 o c, etc. Using these constants with the above equations, you can determine the temperature of the thermistor based on its resistance, or determine a thermistor’s resistance at a particular temperature. Bapi thermistors are thermally sensitive resistors known for exhibiting a large change in resistance with only a small change in temperature. Of teflon encased thermistors add 100 to part no. ±0.22°c @ 25°c (±0.4°f @ 77°f);

Another Important Characteristic Of A Thermistor Is Its “B” Value.

The precon sensor has a dissipation constant in still air at 25°c of 2.7 mw/°c. Web ntc thermistors are usually characterised by their base resistance at room temperature, that is 25 o c, (77 o f) as this provides a convenient reference point. Using these constants with the above equations, you can determine the temperature of the thermistor based on its resistance, or determine a thermistor’s resistance at a particular temperature. This web page will be revised as needed to add new and suggested thermistors.

So For Example, 2K2Ω At 25 O C, 10Kω At 25 O C Or 47Kω At 25 O C, Etc.

Web below are tables and graphs for thermistors commonly found in appliances. Web the resistance of the thermistor will change according to temperature, and should track with the following table. It is the point on the curve after which the temperature coefficient turns positive.

Web A Thermistor Is A Temperature Sensitive Resistor.

At 100°c, resistance is 138.50 ohms. Web bapi thermistors are thermally sensitive resistors known for exhibiting a large change in resistance with only a small change in temperature. ±0.15°c @ 0°c (±0.28°f @ 32°f). The heat dissipation constant is an expression in milliwatts of the power required to raise the temperature of a thermistor 1°c above the ambient.
