CR606 series digital oil level sensor is based on the principle of radio frequency capacitance measurement. It uses tomography scanning technology to dynamically analyze various parameters of the sensor in the medium and automatically compensate accurately. The output signal changes linearly and continuously with the change of liquid level height.The whole machine has no elastic parts and movable parts. It is shock resistant and easy to install. It can be installed in various occasions to accurately measure the oil level of gasoline, diesel oil, hydraulic oil and other weak corrosive liquids.

Advantages：

This series of sensors are metrological measuring instruments with high resolution and measurement accuracy. It calibrate automatically without manual intervention,temperature drift, affection by the medium. That is to say, for the same sensor,no matter whether the measured medium is water,gasoline or diesel, no matter how the temperature changes, it can correctly output the accurate liquid level signal. The problem of difficult measurement of ethanol gasoline, methanol fuel and other media has been solved thoroughly. At the same time, the problem of measurement error caused by the difference of oil label and temperature in different regions has also been solved. At present, this technology is unique in China and is in the leading international level.
