    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� •...
  • Page 8: Function

    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�...
