【Abstract】 In order to satisfy the needs of the real-time on-line monitoring by the vibration and impact in the communication and transportation facilities, a new three dimensional acceleration transducer is developed with unilateral piezoresistive sensor localized on cylindrical surface and overlapped combination. The colibrating results have proved that various technical characteristics fulfil the design requirements. It has been applied to IVA- 1 type intelligent vibration measurer.更多还原
