Application notes
One device provides continuous level and point-level switching, so a single probe can cover a low alarm, a pump on/off pair and a continuous signal for the PLC. The probe is stainless steel 1.4404 with PTFE, can be shortened on site, and the datasheet gives a 5 mm probe accuracy, a 25 mm inactive area at the process connection and a minimum dielectric constant of 5. Process temperature is -20 to +100 C and pressure up to 10 bar.
At commissioning, teach the empty and full points, set the switching outputs to the alarm levels you need, and confirm the analog scaling in the PLC. Foam, coating or a medium with a low dielectric constant can shift the reading, so check against a known level.
Reading the type code before you order
Derived from the datasheet: the series name LS-5xx is followed by a probe-length figure where printed (300 mm here), the output block (analog plus switching outputs as in the datasheet title) and the connector code. The process thread is n/a. Ident number 100001855 identifies this exact version.
Points to confirm with us before ordering: the output configuration, the process thread type (G or NPT), the medium and its dielectric constant, the tank depth against the probe length, and process temperature and pressure. Everything in the table comes from the datasheet as published, so the maker document is the final reference.

About brand
Turck is the German automation company for sensors, connectivity, fieldbus I/O and interface technology. It grew from Hans Turck's engineering office in Mülheim an der Ruhr: in 1965 a chemical plant ordered an isolation amplifier for intrinsically safe circuits, and the first 20 units were built by his brother Werner Turck in Halver. The family-owned Turck group is still headquartered in Mülheim an der Ruhr, with production in Halver and other sites.
Seven Star LLC is an independent supplier in Muscat. We list Turck sensors and I/O devices for machine builders and maintenance teams in Oman and the GCC.

Turck product series
Most of the Turck products here are inductive proximity sensors: threaded M12, M18 and M30 barrels in flush (BI) and non-flush (NI) versions, uprated-range (U) sensors, rectangular CP40 and CP80 housings and BIM magnetic-field sensors for detecting pistons in pneumatic cylinders. The type code describes the sensor; in BI5-M18-AP6X-H1141, BI means flush mounting, 5 is the switching distance in mm, AP6X a three-wire PNP output and H1141 the M12 connector.
Turck also makes RU ultrasonic sensors, PS pressure, TS temperature and LS level sensors, FCI inline flow sensors, the CMVT vibration and temperature sensor for condition monitoring over IO-Link, and fieldbus and Ethernet I/O modules and communication components.
Where Turck sensors are used
Position detection on conveyors, packaging machines, presses and robotic cells; level, pressure and temperature monitoring on hydraulic units and process skids; and vibration monitoring on motors, pumps and fans.
