L129 Series Overview
This 6-3/4 in. (171 mm) deep sight gage allows you to check the condition and level of your oil without shutting down the equipment.
Fingertip adjustable limit contacts, through 4-7/8 in. (122 mm) range, make it simple to set high and low limit contacts. If the float touches the high or low limit contact, a normally open circuit will be completed which can activate alarms and/or shut down 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 electrical circuit. The L129CK1 was designed for applications requiring a three-wire, above ground electrical circuit. It features ungrounded contacts and a conduit hub to protect electrical wiring. Options are available for both models.
When properly installed and maintained, the L129 Series Lube Level Swichgage can monitor and protect engines and pumps from improper lubrication level, which can result in extensive damage.
The L129 Series is recommended for engines and pumps with larger crankcase capacity.
