OptioLaser S300 Liquid Laser Sensor

OptioLaser S300 Liquid Laser Sensor

The OptioLaser S300 Laser can be used for the detection of all types of liquids, regardless of their dielectric properties. This laser can accurately and reliably measure highly reflective liquids, clear liquids and even turbulence liquids. The OptioLaser, due to its narrow beam divergence, can be used to measure through grates and narrow passages, and even next to flat walls. Typical applications consist of tank level, water treatment plant, food and beverage facilities, chemical processing plants, and pharmaceauticals.

Principle of Operation

The OptioLaser S300 Liquid Lasers are user configurable, allowing optimal performance of your specific application. Using an infrared, low-gain GaAs laser diode, light energy of 905 nm. travels to the surface of any liquid and is reflected back. This time-off-light (the time the laser pulse took to travel to the liquid and back) is then calculated into a distance.

The low-gain diode allows for accurate measurement of even highly reflective, clear liquids- regardless of the dielectric properties. The narrow beam divergence of 3 milliradians (equal to 3ft at 1000ft) allows for easy installation, even near walls or thru narrow passages.
