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.

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.

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.

Further Information

D50 Heavy Duty Level Switch

Features

  • High and low floatless level control for tanks and sumps
  • 2 HP 1.5kW 20 AMP 500V S.P.D.T switch
  • No metal parts in contact with liquids
  • Heavy duty all metal housing
  • Weatherproof to IP67
  • Super reliable magnetic action

Applications

  • Level control in confi ned or tight locations
  • Suitable for pump in or pump out applications
  • Water tank level control
  • Effluent and liquid waste level control
  • Suits slurry and high solid applications
  • Suitable for use in sea water, acids and many chemicals
  • Works in sumps. pits, bores, tanks, wells or bunds

OPERATING PRINCIPLE

The D50 two position level switch operates on Archimedes Principle. When non floating solid
displacers suspended from the switch, are immersed in liquid their weight is reduced by an amount
equal to the weight of the liquid they displace. The weight change is detected and used to actuate
a magnetically isolated switch. Surface agitation, froth, floating or submerged solids do not affect the action of the
D50 switch. The displacement principle depends on the specific gravity of the liquid in which the displacers are
suspended. The D50 is set to operate in water with a specific gravity of 0.95 or greater.

L Series

FEATURES
  • Stainless steel or Polypropylene
  • Built in manual override
  • 15 Amp 500 Volt SPDT Switch
  • Unique Seal-less coupling
  • Weatherproof to IP67
  •  Simple to install
  •  Fully serviceable

Description

The L Series side entry level switch provides a reliable accurate and low cost solution to tank level control. The switch is available in all thermoplastic construction in a combination of 316 Stainless Steel and Polypropylene. The level switch can be supplied with a 500 Volt rated single pole double throw microswitch for general control circuit use or with a SPDT reed switch for low voltage low current applications. The L series level switch is built tough to give a long reliable service life in the most arduous applications.
