Abstract

A piezoelectric sensor device, especially for use with a microbalance, with a sensor housing and a holder for holding a piezoelectric sensor element. In order to permit quick exchange of crystals and to minimize the size of the assembly, the holder is configured as a clamping element which has at least one elastic first arm for clamped holding of the contact region of the essentially strip-shaped piezoelectric resonator element, whose measuring region is subjected to a fluid stream to be measured.
