Switch-Tek LH29 Interstitial Leak Detection Switch
™
Application
The general purpose oat leak switch provides
reliable leak detection in and around secondary
containment sumps and tanks with a 1A relay output.
The at body Valox leak sensor is ideal for placement
in hard to reach interstitial areas with limited space.
Switch Open
Switch Closed
In the event of a leak, the foam polypropylene oat
will rise to signal the presence of unwanted liquid in
the containment vessel. The leak detection switch is
typically mounted at on the bottom of the sump oor
or secondary containment tank wall.

Application
Available in general purpose classication, the level controller is offered in three
congurations for pump and valve control. The LC40 accepts one level sensor input
and provides one 10A relay. The LC41 accepts two level sensor inputs and provides
one latching 10A relay for automatic ll or empty control. The LC42 accepts three
level sensor inputs with one latching 10A relay output for automatic ll or empty
control, and a second non-latching 10A relay for high level alarm or low level alarm.
For eld mount installation, add a single or dual indicator NEMA box.
