ifm LMC510 Capacitive Point Level Sensor, 1/2 NPT, Oil

ifm LMC510 Capacitive Point Level Sensor, 1/2 NPT, Oil

The ifm LMC510 is a compact capacitive point level sensor with a 1/2 inch NPT process thread, preset for oils and oil-based media. It has two programmable switching outputs, one of them with IO-Link, which allows a single sensor to give both a pre-warning and a final alarm point if the application allows. The housing is 18.11 mm in diameter and 76.2 mm long, with a 25 mm probe.

It handles tank pressure from -1 to 40 bar and medium temperature from -25 to 100 degrees Celsius, and the protection is IP68/IP69K. Seven Star LLC supplies the LMC510 in Oman and the GCC as an independent supplier.

LMC510 technical specifications

The table lists the values published by the manufacturer for the LMC510. Where a parameter has several operating modes, the headline value is shown; the full parameter list is in the manufacturer documentation.

How the LMC510 works

The LMC510 detects the presence of a medium at the probe tip with a capacitive principle: when liquid, paste or powder reaches the probe, the capacitance of the sensing electrode changes, and the electronics compare it with a stored reference for the selected medium type. The medium type is preset at the factory and can be changed through IO-Link, which tunes the sensing to the product. Because the stainless steel body and PEEK probe have no moving parts, the sensor is not affected by wear, sticking or mechanical float problems.

Where the LMC510 fits and related parts

The LMC510 differs from the LMT sensors in its smaller body, the NPT thread and the broader list of media: water, hydrous media, oils, coolants and powders, with the factory preset for oil. It suits machine tools, gearboxes, hydraulic power packs and compressors, where oil level must be proven without a float switch.

Selection and ordering checklist for the LMC510

Work through the points below before you confirm the order, so that the LMC510 you receive is the one your machine or plant needs.

• Check that the tank has a 1/2 inch NPT tapped port, or an adapter
• Check oil type and temperature up to 100 degrees Celsius
• Decide the use of the two programmable outputs
• Decide on IO-Link
• Consider deposits and foam: the sensor suppresses them, but test with the real oil

The manufacturer lists this article under the type designation Sensor for point level detection, LMFCE-N12E-QSKG-1/US. The article number LMC510 is the reference to quote when ordering, and the type designation is useful for technicians who compare the label on an installed unit.

Installation, commissioning and maintenance

Install the sensor in a nozzle or tank wall so that the probe tip protrudes by the stated length into the product, keeping it away from internal structures and filling jets. Seal it with the correct cone or thread seal for the process connection and observe the allowed tank pressure and medium temperature. At commissioning, select the medium type, run the tank to the switching level and check the output, and then test with product that clings to the probe to see that the build-up is rejected. Inspect the probe from time to time for heavy deposits and keep the M12 connection tight and dry.

Seal the NPT thread with a compatible sealant and do not over-tighten. Mount where the probe is submerged at the alarm level and not in a turbulent inflow. Verify the switching with oil at working temperature, as the response of an oil changes with temperature. If used for both pre-warning and alarm, set the outputs to different logic points.

Typical applications in Oman and the GCC

Used on lube oil tanks, gear and hydraulic reservoirs, coolant sumps on machine tools and compressors in workshops, utilities and oil and gas packages. In hot ambient conditions across the GCC the 85 degrees Celsius ambient limit leaves a margin for enclosed skids.

Level sensors in tanks exposed to Gulf summers must tolerate hot product, condensation on cold nozzles and long periods without attention. Plan a periodic proof test of the alarm point, and record the output state at known levels during commissioning.
