    Introducing the FM Series Heavy Duty Flow Switches

    Suitable for the most arduous heavy-duty applications in industry and mining, the new FM series paddle
    flow switches are built tough.  The entire switch body is CNC machined from solid aircraft grade
    aluminium and 316 stainless steel.  The switch itself is superbly sensitive and it only requires
    4 grams of force against its paddle to actuate its magnetically coupled switch.Two switches are
    available in the FM range, a general purpose 5 to 500VAC SPDT or a 0 to 30VDC SPDT switch with gold
    contacts for low wetting current applications.

    Further information on the FM flow switches can be found by following this link: FM Paddle Flow Switch

    Introducing the LM Series Heavy Duty Level Switches

    A solid range of industrial and mining grade level switches suitable for tank level control in fully exposed
    locations. The entire switch body of the LM level switch is CNC machined from solid aircraft grade aluminium
    and 316 stainless steel. The switch itself is magnetically coupled to its float arm meaning there are no seals or
    diaphragms to leak or fail within the switch.   Two switches are available in the LM range, a general purpose
    5 to 500VAC SPDT or a 0 to 30VDC SPDT switch with gold contacts for low wetting current applications.

    IPG20 Mk2 Intelligent Pump Guard

    Features

    • Learns the operating pressure
    • Fixed or travelling irrigation systems
    • Compensates for change in terrain
    • Cyclic running for pod systems
    • Leak and blockage detection
    • Loss of fl ow protection
    • Displays pressure and set points
    • 20 Bar / 2000 kPa pressure rating
    • Multi voltage operation
    • Manual or automatic operation
    • IP67 rated

    Outline

    The IPG20 Mk2 intelligent pump guard learns the operating pressure each time the system is started
    and then applies the predetermined under and over pressure set points. This allows for highly targeted
    leak and over-pressure detection. Designed for either fi xed pods or travelling irrigators.

    D40 Heavy Duty Single Point Level Regulator

    Features

    • 5 to 500V AC 15A 1.5kW (2HP) Switch
    • No metal parts in contact with liquids
    • 40mm level change on to off or off to on
    • Highly reliable magnetic action
    • Fully sealed IP67 electrical housing
    • M20 cable gland built in
    • Mounting brackets supplied

    Application

    • Confined locations in sumps and pits
    • Bund area warning alarms
    • Cooling tower water level control
    • Bilge water level alarm for boats
    • Suits effluent & high solids uses
    • Suitable for sea water & chemicals
    • Level monitoring in wells & bores

    Operating Principal

    The D40 level switch operates on Archimedes principle. When the non floating Polypropylene
    displacer suspended from the switch is immersed in liquid its weight is reduced by an amount
    equal to the weight of the liquid it displaces. This weight change is detected by a magnet and is
    used to actuate a powerful switch inside the electrical head of the D40. The D40 is designed to
    be used in water with a specific gravity of 0.95 or greater.
