Description
Product Introduction
RF admittance level sensor adopts intelligent radio frequency capacitance technology, no mechanical moving parts. It avoids parasitic capacitance interference that troubles traditional capacitive sensors, delivering stable and high-precision level detection.
It can detect liquid, powder and solid media like quartz sand and iron powder, not affected by tank mounting position. With IP67 / IP69K protection, wide temperature range from -40℃ ~ +85℃, optional PNP/NPN output, widely used for material level monitoring in various industrial tanks and silos.
