Detecting the upper and lower limits of the liquid level in a tank
- This switch incorporates an amplifier and can be attached to the sight tubes and level gauge pipes of semiconductor and FPD manufacturing equipment, etc., to detect liquid level
- Refraction-based detection ensures sufficient gain between light-ON and dark-ON light levels
- A detection method that is suitable for liquids with poor transmittance (photoresist liquid, waste fluids, etc.) and that minimizes malfunctions due to bubbles, water droplets, etc.
