Gavin's Temperature Sensor 

    In most cases, the choice of temperature sensor, to consider the following aspects:

       (1) Whether the temperature of the object to be measured needs to be recorded, alarmed or automatically controlled 

       (2) Whether remote measurement and transmission are required.

       (3) The temperature measurement range and accuracy requirements.

       (4) Temperature component size is appropriate.

       (5) The environmental conditions of the measured object on the temperature measurement device for damage.

       (6) If the price protection, the use of convenient.

    The choice of temperature sensor is mainly based on the measurement range. When the measurement range is expected to be within the total range, the choice of platinum resistance sensor. A narrower range typically requires that the sensor must have a rather high basic resistance in order to obtain a sufficiently large change in resistance. The large enough resistance changes offered by thermistors make these sensors ideal for narrow measurement ranges. Thermocouples are more suitable if the measurement range is quite large. It is best to include the freezing point in this range because the thermocouple indexing table is based on this temperature. The known range of temperature sensor linearity can also be used as an additional condition for selecting a sensor.
