ELS-1100HT Single-Point Level Switch

Brand: Gems Sensors, Inc

These polysulfone level switch units are both compact and economical. They feature a variety of mountings, power requirements and electrical terminations to make it easy to find a perfect match for your application. 

Slightly larger than the ELS-1100, the "HT" or High Temperature version is made from high performance Isoplast plastic. While maintaining broad chemical compatibility, these units also handle fluid temperatures to 100° C (212° F).

They feature 3/8" NPT mountings and the shortest of any of our plastic electro-optic switch bodies – HTS versions are a mere 1/2" long. 

These level switch units are suitable for high, low or intermediate level detection in practically any tank top, large or small. Installation is simple and quick through the tank top, bottom or side. Solid state-switching ensures dependability over long service life.

The sensor offers ±1 mm repeatability and broad liquid compatibility. 

They are not recommended for use in any liquid that crystallizes or leaves a solid residue.
