IPG20 Intelligent Pump Guard

More Information

 

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.

  • 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.
