Description
Of all of the sensing technologies, temperature sensing is the most common. This phenomena can be explained by citing examples in a multitude of applications where knowing and using the actual or relative temperature is critical. For instance, other sensors such as pressure, force, flow, level, and position many times require temperature monitoring in order to insure accuracy. As an example, pressure and force are usually sensed with resistive Wheatstone bridge configurations. The temperature errors of the resistive elements of these bridges can exceed the actual measurement range of the sensor, making the pressure sensor?s output fairly useless, unless the temperature of the bridge is known. Flow and level sensor accuracies are dependent on the density of the liquid or gas.
