ifm LK1022 Capacitive Level Sensor, 264 mm, IO-Link

ifm LK1022 Capacitive Level Sensor, 264 mm, IO-Link

The ifm LK1022 is a capacitive electronic level sensor with a 264 mm probe and an active measuring range of 195 mm, designed for the level in coolant, oil and water-based tanks. Four-digit LED display and a switching output give local indication of the level and allow it to feed a PLC. Within the active range, the set point can be moved in 5 mm steps between 25 and 200 mm.

The probe wetted part is polypropylene and the housing is stainless steel with an IP67 rating. Seven Star LLC supplies the LK1022 in Oman and the GCC as an independent supplier; quote LK1022 in your enquiry.

LK1022 technical specifications

The table lists the values published by the manufacturer for the LK1022. Where a parameter has several operating modes, the headline value is shown; the full parameter list is in the manufacturer documentation.

How the LK1022 works

The LK1022 is a capacitive level probe: the measured medium changes the capacitance between the electrodes in the probe, and the electronics convert the covered length into a level value. The device shows the level on its LED display, and the switching output can be set to a level threshold in 5 mm steps within the active range. The probe is suited to water-based liquids, oils and coolants with a dielectric constant above the stated limit, but not to highly conductive, adhering or acidic media.

Where the LK1022 fits and related parts

Compared with the point level sensors LMT100, LMT121 and LMC510, the LK1022 reads level along a stretch, so it can show a trend and offer an adjustable switch point. Compared with the guided wave radar LR2750, it is limited to mild temperatures (0 to 70 degrees Celsius) and low tank pressure but is simpler and well suited to machine tool coolant tanks and similar systems.

Selection and ordering checklist for the LK1022

Work through the points below before you confirm the order, so that the LK1022 you receive is the one your machine or plant needs.

• Confirm the medium is water-based coolant, water or oil with a dielectric constant above 2
• Rule out extremely conductive or sticky media, granulates, bulk solids and acids
• Check the tank height against the 264 mm probe length and the 195 mm active range
• Check medium temperature (0 to 70 degrees Celsius, short-time 90) and pressure limit of 0.5 bar
• Choose the mounting accessory

The manufacturer lists this article under the type designation Electronic level sensor, LK0264B-B-00KQPKG/US. The article number LK1022 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

Mount the probe vertically through a tank opening with the accessory fitting suited to the application, leaving the stated inactive zones at the top and bottom in mind when you choose the length. Keep the probe away from baffles and fill streams, and use the climate tube accessory when the medium is warmer than the base limit. At commissioning, fill to a known level, adjust the reference point and confirm the switching output at both thresholds. Over time, clean the probe if the coolant forms a film or sludge, and check that the cable is routed away from motor leads.

Mount the probe vertically with suitable accessories, and take the inactive zones (53 mm and 16 mm at the two ends) into account when planning the measuring window. If the coolant is warmer than the base limit, fit the climate tube accessory mentioned in the data. Check measuring error of ±5 % of final value in the planning, and clean the probe if the coolant leaves sludge.

Typical applications in Oman and the GCC

Machine tool coolant tanks, washing machines, and oil reservoirs in workshops are classical uses. In Oman and the GCC the LK1022 is used where operators want to read the coolant level at a glance and PLC alarms for low-level warnings, in fabrication shops, utilities rooms and water-based cooling circuits.

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.
