Overview / Design Principle:
High pressure liquid processes can now be monitored effectively with very little intrusion into tanks or piping. ELS-1200 level switch units feature fused glass prisms fused to zinc/nickel plated, carbon steel housings. You’ll find them to be compact, reliable and durable solutions to liquid level monitoring of refrigerant, compressor oil, hydraulic system reservoirs and machine tools.
Corrosion-Resistant ELS-1200CR - Designed for outdoor use, these corrosion resistant units are made to withstand the nastiest environments. They feature the same fused glass prism and solid-state electronics as the standard ELS-1200. A rugged body made of stainless steel and Hastelloy® delivers the ultimate corrosion protection.
ELS Series Level Switches are 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.
Level switches 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.
