Abstract

Force or pressure measuring device. Between a support member and a force or pressure introduction member elastomeric material is provided which strongly adheres to the two members and is in contact with at least one pressure sensor. With a preferred embodiment the support member is in a potlike form while the force or pressure introduction member is in the form of a piston received by the support member and forming a very narrow gap to the cylindrical surface thereof which gap is essentially completely filled by said elastomeric material.
