dissipation constant การใช้

• The dissipation constant is a measure of the thermal connection of the thermistor to its surroundings.
• If the temperature of the environment is known beforehand, then a thermistor may be used to measure the value of the dissipation constant.
• For example, the thermistor may be used as a flow rate sensor, since the dissipation constant increases with the rate of flow of a fluid past the thermistor.
• Where " T ( R ) " is the temperature of the thermistor as a function of its resistance " R ", T _ 0 is the temperature of the surroundings, and " K " is the "'dissipation constant "', usually expressed in units of milliwatts per degree Celsius.
