INTRODUCTION

Different from our previous liquid level sensors, this capacitive liquid sensor can be used to detect high-viscosity and low-corrosive liquids, such as glue, lubricating oil, grease, ink, engine oil, powder and other special materials. The sensitivity of the sensor can be adjusted by the knob (clockwise to increase, counterclockwise to decrease) to adapt to more media. It has an indicator light to feedback the sensor status in real time, and comes with polarity protection and over-current protection mechanism.

Capacitance contact detection: Determine whether there is liquid and distinguish between liquids by detecting the capacitance of the liquid.

Conical head of anti-hanging-liquid design: Reduces the phenomenon of hanging liquid in detecting.

Special circuit design: Even if there are liquid residues, foam, scabs, etc. in the probe part, the appearance of false signals can be avoided by adjusting the sensitivity.

Stability design: With temperature compensation, the liquid level sensor can detect stably in the range of low temperature -25°C and high temperature 75°C. These detailed designs ensure the stability of detection performance to a large extent.

Material: The head is made of PEEK material, the shell is made of 316 stainless steel, with general anti-corrosion performance, M12*1 standard thread, easy to install.
