Description

The BLSK1 Bilge Level Switch System gives

you all items and fittings necessary to install in

your bilge. Or, you can have only the parts you

want and you provide brackets, tubing and mount-

ing hardware.

Using the proven “Air Cell” actuating system, all

moving parts and switching are remote from bilge

liquids and are thus not affected by corrosion,

rust, etc. All wetted parts are of non-corrosive

materials.

As bilge level rises a column of air is captured in

the MAC1 Air Volume Cell. The rising bilge

level compresses the column of air creating pres-

sure against the large diaphragm in the BLS1

Bilge Level Switch and the switch trips. Switch

set point is adjustable.

The switch resets as the bilge is pumped out. Air

cell recharges itself during normal operation.

The BLS1 is constructed of materials not affected

by marine atmospheres; Aluminum or Bronze

body and cover, Buna-N diaphragm.
