OPTICAL LIQUID-LEVEL SENSORSGENERAL PURPOSE ELECTRO-OPTIC LEVEL SWITCHFEATURES• ELS Series level switches are low-cost, compact, opticallevel sensors with built-in switching electronics. With nomoving parts, these small units are ideal for a variety ofpoint level sensing applications especially where dependabilityand economy are a must.• Level switches are suitable for high, low or intermediatelevel detection in practically any tank top, large or small.Installation is simple and quick through the tank top, bottomor side. Solid state switching ensures dependabilityover long sensor life.• The sensor offers ±1mm repeatability and broad liquidcompatibility. They are not recommended for use in anyliquid that crystallizes or leaves a solid residue.APPLICATIONS• Medical laboratory.• Food and beverage systems.• Pharmaceuticals.• Petrochemicals.• Leak detection.• Hydraulic reservoirs.• Machine tools.765 120 120SPECIFICATIONS• Materials: Polysulfone or Nylon.• Operating Pressure: 0 to 150 PSI max.• Operating Temperature: 0°F to 176°F (-17°C to 80°C)• Current Consumption: 18mA, approx.• Output: TTL/CMOS compatible, open collector output may sink40mA up to 30VDC.ORDER INFORMATION:5395.(Size No.) ELS-1100 ELECTRO-OPTIC LEVEL SWITCHSize No. Description List Price138167 N.O.

Dry Sink, Polysulfone, 10-28VDC, 1/4” NPT 52.25ELECTRO-OPTIC LEVEL SWITCH FOR HIGH TEMPERATURES• Slightly larger than the ELS-1100, the HT or HighTemperature version is made from high performanceIsoplast plastic. While maintaining broad chemical compatibility,these units also handle fluid temperatures to212°F (100°C). They feature 3/8” NPT mountings and theshortest of any of our electro-optic switch bodies - HTSversions are a mere 1/2” long.765 120 130ORDER INFORMATION:5395.(Size No.) ELS-1100 HT ELECTRO-OPTIC LEVEL SWITCHSize No. Description List Price153061 N.O.
