FeaturesSmart Testing Comes with high accuracy within 1.5mm, the noncontact level sensor allows wide testing range and easy operation.Wide Match: high and low level output, suitable for connecting various circuits and product applications, and 5V power adapters.Wide UseAllows wide application to test strong acids, alkalis, boiling water and various liquids, stable and sensitive.Reliable Working: This noncontact level probe has strong antiinterference ability against external electromagnetic interference.Easy to Install Designed to have compact size and light weight, the water level transmitter is simple to install.Specification:Item type: Noncontact water level sensorProduct Model: XKCY23AVExternal Input Voltage Vin: DC5VOutput mode: high and low levelCurrent consumption: 5mA 2mAResponse time: 500mSWorking ambient temperature: 20~80CWorking environment humidity: 5%~100.0%Liquid level accuracy: approx. 1.5mm/0.06 inchesWire length: approx. 300 mm/11.81 inches ( 10 mm/0.39 inches).Wire terminal definition: XH2.543P terminal, brown is the positive pole of the power supply, black is the signal output terminal, and blue is GND.Sealing Performance: IP67Product material: PC VO flame retardant material.Liquid level sensor probe: It is installed on the upper and lower parts of the outer wall of the measured container, which correspond to the high and low levels of the liquid level. The nonmetallic container does not need to be opened, it is easy to install and does not affect production. The probe can detect the liquid level of various toxic substances, strong acids, strong alkalis and other liquids in closed containers at high pressure. The measured liquid is needed to conduct electricity, and the contact surface is nonmetallic, widely used.Package list:1 x Noncontact Water Level SensorNote:1. Do not use double sided cotton foam tape.2. The container must be made of insulating material.3. The container shall be made of uniform materials that are free from an intermediate layer of air, bubbles, water absorption and dielectric constant difficult to modify.Package List1 x Non Contact Water Level Sensor
