Float Switches are inexpensive and efficient liquid level detectors.
They are simple to install, and designed for trouble free operation
over a long life. The LR03 is a plastic float switch moulded to either
a PVC or synthetic rubber 3 core cable. Actuation is via a roller ball
and micro-switch arrangement within the switch thereby eliminating
all heavy metals from this version.
Construction
The unit comprises three major components :
1. The float chamber houses the micro-switch arrangement, totally
sealed within a polypropylene casing, with a single pole double
throw action.
2. The three-cored cable, connected to the micro-switch assembly
inside the float chamber, is sheathed in CPE (chlorinated
polyethylene) synthetic rubber or PVC. This cable is supplied in
three standard lengths, 5 metres, 10 metres and 20 metres ±5% of
the length quoted.
Other cable lengths are available to order.
3. The optional stabilizing weight may be fixed at any point on
the cable using the rubber “O” ring supplied. The weight is sealed
within a moulded polypropylene housing.
In order to provide total positional security in lubricants and
similar liquids, a nylon cable-tie is provided for attachment to the
cable beneath the weight
Mounting
Whilst no hard and fast rules apply to the mounting of these units,
the lead should be supported in an enclosed vessel, and in an open
vessel it is advantageous to clip the lead to the side, especially if
excessive turbulence is experienced.
To obviate the effects of rapid switching conditions that would result
if such turbulence is experienced, it is advantageous to use a
maintaining circuit which both safeguards the micro-switch and cuts
out any chatter in the starters of associated pumps etc
