21. Presumably there is a thermistor wired between the-ve and'S'pins. 22. The dissipation constant is a measure of the thermal connection of the thermistor to its surroundings. 23. It is generally given for the thermistor in still air, and in well-stirred oil. 24. This is because the PPG sensor is more sensitive than a thermistor to minute blood flow changes. 25. These probes consist of a pair of battery-powered thermistors mounted in a fine copper tip. 26. The thermistor is supported by suitable electronic circuitry to maximize sensitivity to minute changes in solution temperature. 27. Thermistors can be classified into two types, depending on the classification of " k ".28. The temperature rise can be measured with a standard type of thermistor , as in a classical calorimeter. 29. The most practical sensor for measuring temperature change in titrating solutions has been found to be the thermistor . 30. Another type of thermistor is a "'silistor "', a thermally sensitive silicon resistor.
