Items supplied • Level sensor LR3000 • Operating instructions In addition, the following is necessary for installation and operation: • 1 rod (for operation of the unit with single probe→ 4.1) • plus 1 coaxial pipe (for operation of the unit with coaxial probe→ 4.2) • mounting material The following components are available as accessories: Rods Length (cm / inch) Order number 24 / 9�5 E43203 45 / 17�7...
Only use rods and coaxial pipes from ifm electronic� The optimum function is not ensured when using components from other manufacturers� For the correct function when used with single probe, the unit needs a large enough metal launching plate� The flange plates that are available as accessories are not sufficient as launching plates (for suitable launching plates → 6.4.1 / 6.4.2).
Applications • Water, water-based media • Oils, oil-based media (only for operation with coaxial probe) • Medium temperature: 0…80 °C (permanent); 0…90 °C (short-term) • Tank pressures: -1���4 bar Application examples: • Detection of coolant emulsion in a machine tool� •...
Function Measuring principle The unit operates to the principle of guided wave radar� It measures the level using electromagnetic pulses in the nanosecond range� The pulses are transmitted by the sen- sor head and guided along the rod (fig� 1)� When they hit the medium to be detected they are reflected and guided back to the sensor (fig�...
