RKL-04 Capacitance Fuel Level Sensor

The sensing part of the RKL-04 Capacitance Fuel Level Sensor is a coaxial capacitor, when the liquid enters the condenser caused the change of the sensor shell and sensor capacitance between electrodes, the variation through the subsequent acquisition and conversion circuit and precise linear and temperature compensation, the output field required standard voltage, current, the digital signal, sampling frequency is adjustable. Food grade Teflon and 304 stainless steel material with fully welded structure, high health level, high breaking strength; Long – term stability, high reliability. Used for measuring: oil (gasoline, diesel oil, hydraulic oil, lubricating oil), water (sewage), beverage, medical treatment, chemical and other liquid media, suitable for high and low temperature, or even viscous liquid media occasions. Extremely wide measuring range: 0.03……6m, especially suitable for measuring liquid heights below 500mm.
