Abstract
The invention relates to a piezoelectric force sensor (1) comprising a housing (10) having at least one piezoelectric body (11) and an electrode (12) electrically connected to said body (11), wherein a connection device (13) for forwarding measurement signals having a contact pin (131) is fastened or molded on the housing (10). The contact pin (131) is connected to the electrode (12) in an electrically conductive manner. According to the invention, a helical compression spring (14) is electrically conductively connected to the contact pin (131) as an electrical connection within the piezoelectric force sensor (1). For this purpose, the helical compression spring (14) is removably electrically conductively connected to the electrode (12) in an operative manner so that the contact pin (131) has a spatial clearance from the electrode (12) and measurement signals from the electrode (12) can be extracted from the housing (10) of the piezoelectric force sensor (1) via the helical compression spring (14) and the connected contact pin (131) and can be picked up on the connection device (13).
