Temperature is one of the most frequently measured physical phenomena. However, if a traditional thermocouple or resistive temperature detector (RTD) isn't appropriate for a specific application, thermistors and monolithic linear temperature sensors are suitable for temperatures from -50 to 150 [degrees]C.
Both sensor types are relatively inexpensive and easy to configure because no reference junction is required. Both provide good performance with instruments of moderate sensitivity. The thermistor's large change in resistance per degree Celsius facilitates high-resolution measurements. Monolithic linear temperature sensors provide a very linear output easily ...
