SICK SENSORS
SICK LFP Cubic Level Sensors
- Level sensor for liquids
- No mechanical moving parts
- Interchangeable and retractable probe from 200 mm to 2,000 mm and cable probe up to 4,000 mm
- Resistant to deposit formation
- Process temperature up to 100 °C, process pressure up to 10 bar
- 3-in-1: combined display, analog output (according to NAMUR NE 43), and binary output
- High enclosure rating of IP67, rotatable housing and remote amplifier
SICK LFP Cubic – BENEFITS
- Rugged design increases service life
- High flexibility due to cutable and exchangable monoprobe or rope probe
- Cost savings due to multiple output signals: one system for both level detection and continuous level monitoring
- Time and cost savings due to low maintenance without any calibration and quick commissioning
- Titanium process connection brings high chemical resistance
- Compact and rotatable housing or remote amplifier ensures flexible installation
- No crosstalk when several sensors are mounted next to each other
- Advanced technology enables adjustment-free measurement
SICK LFP Cubic Level Sensors are hygienic level sensors for liquids using TDR technology – a process for determining the time of flight of electromagnetic waves. The time difference between the sent pulse and the reflected pulse is used to generate a level signal, both as a continuous value (analog output) and a freely positionable switching point (switching output).
The LFP Cubic is compatible for use in virtually any liquid and as a result of its modular probe the sensor can be integrated quickly into any application. It can even be used in deposit-forming and foaming liquids. The LFP Cubic sensor’s intuitive setup uses four push buttons and a display to ensure quick and easy adaptation to the application.
SICK LFP modular connection system allows simple and flexible installation in any application – with high temperature and pressure resistance, unrestricted use is possible under CIP and SIP conditions. Communication capability via IO-Link to the superordinate control units.

LIQUID LEVEL SENSOR APPLICATIONS
SICK LFP Cubic Level Sensors enables both continuous level measurement and point level measurement of liquids in metal containers, tanks and vessels – this includes liquids that foam or film.
- monitoring coolants and lubricants in machine tooling
- monitoring cleanser and detergents in cleaning and washing machines
- monitoring filling tanks in automobile assembly
- level measurement in industrial processes with difficult ambient conditions
hydraulic pump -Measuring Pressure, Level & temperature
The SICK LFP Cubic Level Sensor monitors the level of hydraulic oil in the unit within the four programmable switching thresholds and prevents the pump from being damaged due to a low oil level.
