Thermistors are characterised by their base resistance and their B value. The base resistance, for example, 10kΩ, is the resistance of the thermistor at a given temperature, usually 25oC and is defined as: R25. The B value is a fixed material constant that describes the shape of the slope of the … Meer weergeven A thermistor is basically a two-terminal solid state thermally sensitive transducer made from sensitive semiconductor based metal oxides … Meer weergeven While the change in resistance due to heat is generally undesirable in standard resistors, this effect can be put to good use in many temperature detection circuits. Thus … Meer weergeven Thermistors are available in a range of types, materials and sizes depending on the response time and operating temperature. … Meer weergeven Also, being a solid state device made from highly sensitive metal oxides, they operate at the molecular level with the outermost (valence) electrons becoming more active and producing a negative temperature coefficient, or … Meer weergeven WebIn addition, the B constant indicates a slope of the change in resistance of the Thermistor due to a temperature change, and is the basic characteristic of an NTC Thermistor. …
