เซ็นเซอร์วัดระดับของเหลว น้ำ Liquid level sensor, liquid level detection sensor, water level monitoring sensor module

Liquid level sensor is using the infrared optical principle, will detect the liquid level, liquid level signal through the optical transmission, converted to electrical signal output, by identifying with the voltage signal of liquid level sensor, the sensor design is compact, small size, waterproof drilling, cylindrical shape and convenient installation;
The installation method is diversified, can be mounted, lower, side, inclined to install, the sensor head is smooth, cleaning is easy, and the precision is superior to float type liquid level switch, the controllable accuracy is at plus or minus 0.5mm.
In addition, the accuracy of the existing float type liquid level switch is + 3.0mm;
Light principle, frictionless and other mechanical moving parts, the service life is greatly increased;

Technical parameters:
1. Working voltage: DC5V 
2. Operating current: <10MA.
3. Output mode 1: analog output 0-4.5v.
4. Output mode 2: high/low level signal output.
5. Response time: <500ms.
