Estimating the term…
The invention relates to a cell for measuring a piezoelectric resonator, which has a first casing body and a second casing body, and a quartz resonator configured as a wafer having metal layers on both sides as electric contact surfaces, the first casing body having coupling features and the second casing body having coupling slots, the coupling features being configured to be assembled in the coupling slots when the measuring cell is in a working position, such that the first casing body is assembled in the second casing body when pressure is exerted on the first casing body until the surface of the lower end of the first body makes physical contact with the upper surface of the second casing body and, subsequently, the first casing body is rotated to one side of the axis of symmetry of the measuring cell.
Measurement cell of a piezoelectric resonator (15) comprising a first casing body (12) and a second casing body (13) wherein the resonator (15) includes at least two electrical contact electrodes (16), characterized in that the first casing body (12) comprises coupling ridges (24) and the second casing body comprises engaging grooves (23) wherein the coupling ridges (24) are configured to be assembled into the engaging grooves (23) when the measurement cell (11) is in working position.
Measurement cell according to any of the preceding claims characterized in that the resonator (15) is of the piezoelectric resonator type (15), a piezoelectric quartz crystal resonator or similar.
