ExOsense Piezo-Resonant Liquid Level
Quick Specs...
Overview / Design Principle:
The new ExOsense is the first and only affordable, non-intrusive liquid level sensor for plastic fluid containers. ExOsense sensors adhere to the outside of plastic bottles and are unaffected by the color or transparency of the plastic. Liquids inside the bottle are untouched, so with ExOsense there is no issue of material compatibility or contamination. Best of all, ExOsense sensors fit any size and shape vessel, from small bottles, to large tanks. The Exosense sensor head features a peel-and-stick adhesive face that can be affixed anywhere on the outside of the tank to provide high, low or any intermediate point level fluid sensing. A detachable USB type mini-cable feeds the solid-state switch unit. Equipment Used On: Hematology, Immuno-chemistry, Histology, Medical Laser Systems, Hemodialysis, Cytology.
