The capacitance oil level sensor adopts capacitance formed between the internal and external metal tubes to change linearly with the object (oil) level, and transform the change amount of the object (oil) level into a linear 4-20mA, 0-5V, digital RS485 output, which can directly display the liquid level height or be sent to the remote monitoring system via satellite.

The capacitance oil level sensor can be applied to the precise measurement of oil level in fuel tank of automobile, oil tank truck and oil depot, etc., and the whole machine has no movable or elastic parts. It has characteristics of shockproof easy installation, high reliability, high precision and good high performance, and is also suitable for measurement and monitoring of various non-conductive liquid . The core components of the product adopts international advanced highly integrated special IC chip, which can be transformed into standard analog signal or digital signal through precise temperature compensation and linear correction.
