Capacitive Level Sensor

The high accuracy capacitive level meter adopts a fully digital capacitance measurement method and uses multi-parameter compensation technology. It can automatically adapt to various media without re-calibration. It has the advantages of simple structure, high resolution, reliable operation, fast dynamic response, non-contact measurement, and can work under harsh conditions such as high temperature, strong corrosion, severe toxicity, explosion and strong vibration. It is not affected by factors such as dielectric constant changes, temperature changes, steam interference and hanging materials. It is a great option for truck tank fuel level sensor.
