Abstract

LA INVENCION SE REFIERE A UN SENSOR DE GOLPES PARA SU CONEXION DIRECTA O INDIRECTA A UN MOTOR DE COMBUSTION INTERNA DISPONIENDO DE UNA CARCASA (10) CON UN MANGUITO (11) A PRESION, SOBRE CUYA PARTE EXTERIOR SE ENCUENTRA COLOCADA UNA PLACA PIEZOCERAMICA, UNA MASA (16) SISMICA ACTUANDO COMO TAL, LAS PLACAS (14) DE CONTACTO Y LAS PLACAS (13) DE AISLAMIENTO. LAS PLACAS (13) DE AISLAMIENTO DE LA PLACA (15) PIEZOCERAMICA SON LIGERAMENTE CONDUCTIVAS ELECTRICAMENTE DE FORMA QUE EL PICO DE VOLTAJE PRODUCIDO MEDIANTE EL EFECTO PIROELECTRICO PUEDE SER FACILMENTE DERIVADO. DE ESTA FORMA ES POSIBLE LA PREVENCION DE MEDIDAS ERRONEAS Y LA INTERFERENCIA EN EL CIRCUITO ELECTRICO CONECTADO AL SENSOR DE GOLPES.
