Operating Principles

When an electromagnetic pulse is applied on the sensor probe, the pulse proceeds at high speed toward the measurement surface via the wire, and a part of the pulse is reflected on the measurement surface and returned to the sensor. The distance to the measured substance is calculated from this propagation time.
