The SP series offers a wide array of thermal flow switched that are constructed in accordance to the principle of thermal dispersion. A typical arrangement utilizes 2 temperature detectors that are installed within the tip of the sensor. The first temperature detector is heated a few degrees more than the second one. When the process medium passes over the tip of the sensor, it disseminates some of the heat from the temperature detector. Transformed into electronic signal, the delta temperature is a function of flow velocity.
