Capable of detecting liquids through clear or translucent containers, the SA1W sensor is one of the fastest, most reliable, moisture detection sensors on the market.
This is one of the fastest, most reliable, moisture detection sensors on the market.
Using a laser beam tuned to the resonant frequency of an H2O molecule, the SA1W sensor is able to detect any liquid or paste containing water molecules - without contact! Capable of detecting liquids through clear or translucent containers the SA1W has a long sensing range of up to 800mm and can use either through beam or diffuse reflected fibre cables.
The SA1W uses a small diameter laser beam for precise level detection and has a visible red spot for easy targeting and alignment.
Eliminates many of the problems associated with other photoelectric sensors, capacitive sensors, ultrasonic sensors, vision systems or moisture meters.
