Global Waters WA150Tilt Float Switch is an inexpensive, efficient and highly reliable leveldetector for open vessels, sumps and ponds. The Tilt Float Switch’s moldedrubber float has an integral three conductor cable and operates on amicro-switch device that is located inside the rubber float on an anti-vibrationmount. The WA150 Tilt Float Switch includes an adjustable cable weight,which allows it to be suspended from a convenient location above the waterrather than having to tie it off at your desired actuation point. The TiltFloat Switch’s rubber float is constructed of EPDM, a synthetic rubber withrigid and durable characteristics for long service life and resistance to heat,oxidation, ozone and aging due to weather. As a non-polar elastomer, EPDMhas good electrical resistivity, as well as resistance to polar solvents such aswater, acids, alkalies, phosphate esters and many ketones and alcohols.
The WA150 Tilt Float Switch’s basic operating principle is that as the fluidlevel rises the rubber float will rise, causing the micro-switch to tilt andgenerate a signal that can be used to operate a motor starter, open or close avalve or actuate indicator alarms as required. The Tilt Float Switch’s3-lead cable allows operation on increasing level or decreasing level. Onelead is common, one is normally open (NO), the other is normally closed (NC).
Tilt Float Switch Installation Notes
There are no specific installation concerns for the WA150 Tilt Float Switch. However, the Tilt Float Switch’s lead cable should be supported in an enclosedtank. Additionally, in an open tank, sump, or pond, it is advantageous toclip the Tilt Float Switch’s lead cable to the side, especially if excessiveturbulence is experienced (a nylon cable-tie is included).
To alleviate the effects of rapid switching conditions if such turbulence isexpected, it is recommended that a maintaining circuit be used to both safeguardthe Tilt Float Switch’s micro-switch and cut out any chatter from the startersof associated equipment, such as pumps.
An optional stabilizing weight and rubber “O” ring are includedwith the WA150 Tilt Float Switch. This may be installed at any point onthe Tilt Float Switch’s lead cable.
