Level detector is an op-amp circuit that compares two inputs and provides a DC output indicating the polarity relationship between the inputs. This is also used to rectify the input signal and give a DC output proportional the peak or RMS level of the input signal. It is used for detecting a level of a liquid, which is provided with an elongated probe having opposed proximal and distal ends. Its distal end of the elongated probe is submerged beneath the level of the liquid with an unwetted length of the elongated probe located above the level of the liquid. It contains a thermal conductor or an electrical heater, which is used for maintaining a temperature difference between the proximal end of the elongated probe.

RF Capacitance transmitter is a multi-function transmitter that offers the user unparalleled power. It can interface with two separate vessels, while software mathematics allow for the total or difference of the two measurements. As the media rises and falls in the tank, the amount of capacitance change between the probe and the ground reference also rises and falls. The electronics convert this capacitance change into a continuous level measurement. It is suitable for hydrocarbons, solvents, interface and high temperature and pressure liquid applications.

RF level sensors are widely used in liquid or bulk material applications. This switch includes integral electronics mounted on the probe. As material makes contact with the probe, there is an increase in the capacitance. This is detected by the electronics and converted to relay activation. It is ideal for dry bulk material application.
