The L129 Series Lube Level Swichgage instrument is a combination lube level indi- cating gage and adjustable low and high limit switches. It provides protection against low oil level or high level caused by overfill or fuel or water seepage into the crankcase.
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.
Options are available for both models. A flow restrictor plug is available that restricts oil flow from the crankcase to the L129 Series switch and vice versa. It is typically used on applications where the engine is not stationary such as marine and mobile equipment.
The L129 Series Lube Level SWICHGAGE®, when properly installed and maintained, can monitor and protect your engines and pumps from improper lubrication level, which can result in extensive damage.
