Impact-induced pulse sensor

An impact-induced pulse sensor comprising:

• a housing having a longitudinal axis;
• guiding means arranged on said housing;
• a sensor element adapted to be displaced within said housing along said guiding means when an essentially pulse-shaped impact of a given duration is exerted on said housing, said sensor element being displaced with a predetermined speed (dx/dt) and along a predetermined distance (x), said guiding means being configured such as to affect said speed (dx/dt), said sensor element, further, being made of a magnetic material;
• pickup means rigidly connected to said housing for magnetically generating a measuring signal (Ui;
• UM) derived from said displacing of said sensor element caused by said impact;
• said sensor element, when displaced, generating in said pickup means a measuring voltage (UM) depending from said distance (x), said guiding means affecting said speed (dx/dt) such that for impacts with like pulse areas said measuring voltage (UM) vs said distance (x) is independent from said duration of said pulse-shaped impact.
