{"title":"Capacitive Liquid Level Sensor for Arduino","handle":"capacitive-liquid-level-sensor-for-arduino","url":"/products/capacitive-liquid-level-sensor-for-arduino","description":"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.            PrecautionsThe liquid sensor should not be used in the following cases:Temperature exceeds 75°CPressure higher than 0.3MPThere is dry glue on the probe that can't be removedFeaturesCan detect high viscosity and low corrosive liquidsConical head of anti-hanging-liquid designNPN+PNP dual outputApplicationsDetect high viscosity and low corrosive liquidsSpecificationDetection Mode: Contact detectionDetection Principle: Capacitive detectionPower Supply Voltage: 12-24VDetection Object: High viscosity and low corrosive liquidSpeed: Response speed is 20ms, switch output frequency is 50HzOutput Signal: NPN+PNP Dual OutputOutput Current: Max100mAWorking Power: <0.5WWorking Temperature: -25°C~+80°CProtection Level: IP65Appearance Material: PEEK/316 stainless steelProtection Mechanism: Polarity protection, over-current protectionWiring Instructions: Brown-positive, blue-negative, black-NPN, white-PNPShipping ListCapacitive Liquid Level Sensor     x1Screwdriver     x1","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2677,"title":"Default Title","sku":"DF-SEN0507","price":99.89,"on_sale":false,"in_stock":true,"available_quantity":6,"option1":"Default Title"}]}
