The L129 Series Lube Level SWICHGAGE ,
A 6-3/4 inch (171 mm) deep sight gauge
allows you check the condition and level of
your oil without shutting down the equipment.
Fingertip adjustable limit contacts, thru
4-7/8 inch (122 mm) range, make it simple to
set high and low limit contacts. If the float
touches the high or low limit contact, a normal-
ly open circuit will be completed which can
activate alarms and/or shutdown the equipment.
There are two models in the L129 Series:
L129 and L129CK1. The L129 model is
designed for grounded, low voltage electrical
systems. It features a one-wire-to-ground elec-
trical circuit. The L129CK1 was designed for
applications requiring a three-wire, above
ground electrical circuit. It features unground-
ed contacts and a conduit hub to protect
electrical wiring.
