Overview / Design Principle:
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.
The ELS Level Switch Series is low cost, compact, optical, 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.
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 ±1mm repeatability and broad liquid compatibility. They are not recommended for use in any liquid that crystallizes or leaves a solid residue.
Applications:
- Medical Laboratory
- Food and Beverage Systems
- Pharmaceuticals
- Petrochemicals
- Leak Detection
- Hydraulic Reservoirs
- Machine Tools
