Lube Level Maintainer
LM500-TF-ATEX.
The LM500-TF-ATEX maintains oil level on any size engine. It also supports installations that require a three-wire, snap-action switch. The form C (three-wire) contact allows a controller/annunciator to be wired as a closed-loop system, resulting in a reliable fault-sensitive circuit.
Refer to LM500 Series Flow Rate Chart for application data. The Murphy LM500-TF-ATEX Oil Level Maintainer includes a test feature that confirms both the float and switch are Operating correctly with a single press of the test button. The LM500 series maintains the crankcase oil level of an engine, pump or compressor. Adjusted to the correct running oil level, it will replenish oil as it is used. The low-level switch will alarm and/or shut-down the equipment, if supply oil is lost and the equipment continues to use oil. As crankcase oil level drops, the LM500 float also drops and opens the Thumb-Valve™. This allows oil to flow from the supply tank through the LM500 and into the crankcase.
When proper level is achieved in the crankcase, the LM500 float rises causing the Thumb Valve to close off further oil flow. The simple and unique Thumb-Valve is non-clogging and provides a positive, leak-free seal. If the clean oil supply is depleted and oil level continues to fall, the low-level switch will operate an alarm or equipment shutdown.
Estimate available in 40 working days from Italy to Italy.
