    Warrick 16 Liquid Level Controller

    Manufacturer Series Controller Type
    Warrick 16 General Purpose

    Gems® type 16 open circuit board controls are engineered for general purpose single-level or differential applications. They feature spade terminals for easy wiring and provide sensitivities up to 1 million ohm/cm. The 16D has the same features and specifications as the 16, but also has DPDT load contacts to eliminate the need for slave relays. Common applications include single-level service, point level, valve control, low-water cutoff, differential service, alarms, and pump control.

    Warrick 16M Liquid Level Controller

    Manufacturer Series Controller Type
    Warrick 16M General Purpose

    Gems® type 16M solid state plug-in modules are designed for either differential or single-level service. They feature U.L. “Motor Controller” listing, an 8 pin socket with screw type connections for easy installation and service, and a sensitivity up to 1 million ohm/cm. Series 16HM provides higher sensitivity up to 5.5 million ohm/cm and a probe voltage of 12VDC for applications with low conductive media. Series 16DM has DPDT load contacts, 11 pin octal plugs, and eliminates the need for slave relays. Series 16VM features field adjustable sensitivity through external setpoint resistors and uses an 11 pin octal socket.

    Warrick 26 Liquid Level Controller

    Manufacturer Series Controller Type
    Warrick 26 Low-Water Cutoff

    Gems® type 26 low water cut-offs are designed for boiler low water cut-off protection. A snap-through standoff mounting device is available. Optional power outage feature resets after nuisance outages, and an optional reset button is used when device has been deactivated because of low water condition. An optional test feature allows LLCO circuit to be tested without draining the water. A built-in 3 second time delay is standard, with up to 90 seconds available for increasing and decreasing levels.

    Warrick 3B Electrode Fitting

    Manufacturer Series Fitting Style Probe Type
    Warrick 3B NPT w/o Head

    Gems® type 3B fittings are compact pressure tight assemblies that hold a single electrode probe for use in water and chemicals. These fittings incorporate a ¼-20 female thread that must be combined with a Series 3R (rigid rod electrode) or Series 3W/3Y (wire suspended electrode) to make a complete assembly.

    Warrick 3C Electrode Fitting

    Manufacturer Series Chamber Type
    Warrick 3C Short

    Gems® type 3C side chamber fittings are cast iron or brass, pressure-tight chambers containing up to four probes from 1½” to 6″ in length. Pipe tappings provide connection to the side of boilers and pressure vessels to equalize the level in the chamber with the level in the vessel. Common applications include boilers, hydropneumatic tanks, steam generators, pressure vessels, pump operation, and low water/high water alarm.
