Abstract
A radar level gauge system comprising a transceiver; an elongated two-conductor probe having a signal conductor connected to the transceiver, and a rigid shielding conductor spaced apart from the signal conductor by an open space. The two-conductor probe extends from an upper probe end to a lower probe end; and processing circuitry for determining the filling level based on a transmit signal and a surface echo signal. The shielding conductor exhibits an open cross-section profile, in a cross-section with a plane perpendicular to the two-conductor probe, along at least a portion of the two-conductor probe. The two-conductor probe further comprises a plurality of spacer arrangements. Each spacer arrangement includes at least a first spacer member attached to the rigid shielding conductor and arranged between the signal conductor and the rigid shielding conductor for preventing contact between the signal conductor and the shielding conductor.
