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.

|---|---|
| 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 easy solution for thin wall tanks (1/4" thick):ELS-1100FLG Series Level Switch. No threads needed with these flanged units. Slip through a .75" hole and tighten the jam nut; Viton gasket forms a tight seal. Ideal for sheet metal, molded plastic tanks and medical applications where elimination of exposed threads removes potential bacterial breeding grounds. | |
| 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 212°F (100°C). They feature 3/8" NPT mountings and the shortest of any of our electro-optic switch bodies-HTS versions are a mere 1/2" long! | |
| When high purity or resistance to chemical attack is vital, ELS-1100TFE sensors are the ultimate solution. They feature a pure Teflon body and prism construction. Even the Hypalon vapor barrier and Teflon coated lead wires give evidence to the care we've taken to make the perfect liquid level sensors for pharmaceuticals, semiconductor manufacturing, food and beverage, chemical processing, or anywhere purity or chemical resistance is the major criteria. | |
| The ELS-1150 electro-optic level switch maintains the top-performing environmental capabilities of their larger family members while featuring an overall size that is 50% smaller. At just 1.38" long, the nickel-plated carbon steel ELS-1150 represents the smallest electro-optic level sensor in its performance class, and by far the most economical. ELS-1150 switches utilize a strong, glass prism fused to a carbon steel housing to easily monitor vessels pressurized up to 2500 PSI. Their compact package size makes them the ideal candidate for monitoring the small, pressurized vessels found in HVAC, refrigeration and hydraulic applications. They are most commonly used for low, high and intermediate level detection. A Stainless Steel version, the ELS-1150SS, is excellent for applications requiring corrosion resistance. Industry's only stainless steel electro-optic sensor offers greater compatibility and is ideal for acids, solvents, and dielectric water applications. | |
| 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 a compact, reliable and durable solution to liquid level monitoring of refrigerant, compressor oil, hydraulic system reservoirs and machine tools. | |
| These electro-optic switches feature a one piece removable electronics module. | |
| Not only is the ELS-900 the smallest electro-optic liquid level sensor in our arsenal, but it also carries the highest operating temperature capability at 125°C. The Polyethersulfone housing ensures this sensor is compatible for use in a broad range of medias. The ELS-900 is an excellent value making it a perfect choice for industrial OEMs desiring an extremely small, 'no moving parts' sensor rated for high temperatures. |
