Pressure sensor protecting device

The utility model discloses a pressure sensor protecting device which comprises a housing body and cover plates. The cover plates are fixedly connected at an opening of the housing body. The housing body has a hollow cylindrical structure and is used for accommodating a pressure sensor. Intervals between the pressure sensor and the housing body and axial translation plates prevent influences of long-term or instantaneous mechanics disturbance on the measuring precision of the sensor, and influences of external temperature change on the pressure sensor are minimized. The pressure sensor protecting device overcomes a defect that a conventional pressure sensor is easy to be influenced by external mechanics disturbance, and can be applied to air pressure and liquid pressure measurement under a complex load environment.
