Both devices work on the same principle that a constant current flowing through the resistor, and its changing resistance due to change in temperature, is measured as a voltage drop across it. Ultrasonic density meters work on various principles to calculate the density. The main difference is that the electrical resistance of the resistor used in a thermistor varies in a non-linear manner with respect to temperature. The dial is connected through a circuit to the temperature sensor (a bimetal strip, shown here colored red and blue), which switches an electrical circuit on and off by bending more or less. The CAT6095 measures temperature at least 10 times every second. Before understanding how the sensor works, it is worth looking at some of the terminology used as this is extremely useful to know when identifying a sensor.
