  • Gems Opto-Pak Controllers

    Item Type Moving or Non-Moving Parts Technology Body Material
    OEM, Switch/Transmitter Electro-Optic Plastic, Other

    Gems® Opto-Pak Controllers convert standard 110 VAC line current to the 12 input power required for ELS-1100 and ELS-300 operation, and provide an SPDT, 5 Amp relay output for direct control of moderate loads. Two models are available: an open circuit board Opto-Pak Controller for incorporation into custom enclosures, and the self-contained, NEMA 4X model pictured here.

  • Gems WIF-1250 LevelSwitch

    Item Type Moving or Non-Moving Parts Technology Body Material
    OEM Non-Moving Parts Conductive Other

    Gems® type WIF-1250 sensors are innovative, no-moving parts solutions specifically designed to detect the presence of water in fuel. They are an ideal solution for OEM's of off-highway vehicles, locomotive and generator sets. They are also idea for use with fuel filters. Based on reliable conductivity technology, WIF-1250 sensors are built from robust nickel plated steel for compatibility with temperatures up to 257°F and are suited for the most challenging environments or applications. A 5-second delay prevents “slosh” actuation. The sensor is easily mounted in any position.

  • Gems XLS-1 Level Switch

    Item Type Moving or Non-Moving Parts Technology Body Material
    OEM Non-Moving Parts Ultrasonic Stainless Steel

    XLS-1 ultrasonic level sensors are compatible with water-based and hydrocarbon based liquids, and are perfect for applications where condensation may affect other sensing technologies. The XLS-1 is an ideal solution for sensing liquid level in generators, water tanks, radiators, printers, and other industrial applications. XLS-1 ultrasonic level switches expand the Gems catalog of solid-state level sensors.

  • Harwil L-21N/L-21VCR Level Switch

    Item Type Moving or Non-Moving Parts Technology Body Material
    Industrial, OEM Moving Parts Float Plastic

    Harwil® type L-21N & L-21VCR industrial level switches are low cost, high performance switches made from highly durable plastics. They feature a variable liquid differential and a single point pump up/pump down level control. Interchangeable differential band modules, for all non L-21+ versions, allow for 5 minute on-site switching of differentials from 1″ to 2″ to 3″ to 5″ in any sequence to satisfy variable operational requirements as they occur.

  • Harwil L-40N/L40VCR Level Switch

    Item Type Moving or Non-Moving Parts Technology Body Material
    OEM Moving Parts Float Plastic

    Harwil® type L-40N & L-40VCR side and top mount switches are made of corrosion resistant plastic with an optional metal pin available in 316 stainless steel, Hastelloy C, titanium, Tantalum, or Teflon. They are ten times less sensitive from deposit and build-up of contaminants than sliding float models and are meant for use in particle contaminated fluids.

  • Harwil L-5/L-5SS Level Switch

    Item Type Moving or Non-Moving Parts Technology Body Material
    Industrial Moving Parts Float Brass/Bronze, Stainless Steel

     

    Harwil® type L-5 & L-5SS industrial level switches feature continuously adjustable float buoyancy control to allow use in fluids with specific gravity down to 0.6. Continuous buoyancy control allows switch activation at oil/water interface. These switches may be used in hazardous areas when used with intrinsically safe relays. They feature a high/low liquid level alarm, solenoid valve on/off control, and horizontal mounting.
