Product 3D Image Get couponsLFP Series RF Capacitance Level Transmitter
Product introduction
The RF capacitance level transmitter operates based on the principle that changes in material or liquid level cause a change in capacitance. The probe and the conductive tank wall form an equivalent capacitor. When the probe is in air, the capacitance (CA) is low. As material fills the tank and adheres to the probe, the capacitance increases. When the tank is full and the probe is completely covered, the capacitance reaches its maximum (CB). The measurable range is the difference in capacitance (ΔC = CB - CA), recommended for use within ΔC = 25 to 2000 pF.
