FM PRESSURE METER

The utility model relates to an FM pressure meter capable of being used for measuring the pressure intensity of fluid and the basic pressure stresses of buildings and also capable of being used for measuring the pressure stress of rocks, concrete and soil bodies which are transferred by flat metal liquid bags. The natural vibrating frequency of the tungsten string inside the permanent magnetic gap of the utility model is outputted to an FM signal by the modulation of the deflection of the pressure measuring sensitive film, so the FM pressure meter can not be distorted by the remote transmission. The tungsten string relative to a basal plate and the pressure measuring sensitive film adopts a welding connection and a differential compensation measure and can eliminate the error of the temperature and reduce the zero drift. The utility model can give the digital information of the pressure metered on line in real time.
