Sensors: Liquid Level related categories

Electro-Optic Level Switchs
ELS Series Level Switch Sensors are low cost, compact, optical water level sensors with built-in switching electronics. With no moving parts, these small units are ideal for a variety of point level sensing applications — especially where dependability and economy are a must. Level switch sensors are suitable for high, low or intermediate level detection in practically any tank, large or small. Installation is simple and quick through the tank top, bottom or side. Solid state-switching ensures dependability over long service life. These water level sensors offer ±1mm repeatability and broad liquid compatibility. They are not recommended for use in any liquid that crystallizes or leaves a solid residue.
Ultrasonic Type Level Sensors
Gems ULS Series of ultrasonic level sensor instruments are designed for a broad spectrum of viscous to light liquids; including some of the most challenging liquids you may deal with: acids, freon, paints, lacquers, etc. They’re built to withstand high temperatures and pressures with welded stainless steel sensor probes that have no seals to leak and no moving parts to wear out. ULS Series ultrasonic level sensor instruments are unaffected by variation in temperature, pressure, density or type of liquid. In most cases, electronics are housed in cast aluminum, NEMA 4/NEMA 7 explosion proof and water tight enclosures.

ExOsense
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.
