How Digital Thermometers Work
Digital thermometers contain a small computing mechanism and a resistor. A change in temperature causes the sensor to notice a change in resistance. The computer converts the difference in resistance into a difference in temperature and offers a digital readout in degrees. The thermoresistor sensor is called a thermistor.
High-quality digital thermometers like the MOBI Flex Temp Flexible Tip Thermometerare available for a relatively low cost because good thermistors are available at a low cost. When a quality sensor is combined with other quality parts and a well-designed housing, the result is a useful and accurate instrument that can serve the whole family for years.
Thermistors are used in a variety of electronic devices where changes in temperature must be taken into account. They can take the place of circuit breakers or fuses to shut down temperature-sensitive electronics to prevent overheating damage. They can also be used in heating and air conditioning thermostats. In that case, they replace bimetallic strips or mercury sensors, which are more likely to fail.
