Problems solved by technology
[0004] Aiming at the deficiencies of the prior art, the present invention provides a new type of differential pressure sensor, which has the advantages of preventing the differential pressure sensor from interfering with peripheral electronic products while avoiding the external electromagnetic interference of the differential pressure sensor, and solves the problem of the existing differential pressure sensor. The sensor has poor anti-electromagnetic interference ability. It is not only susceptible to external electromagnetic interference, but also easy to cause electromagnetic interference to surrounding electronic products. It is difficult to use it in electromagnetic field sensitive occasions.

The invention relates to the technical field of differential pressure sensors, and discloses a novel differential pressure sensor which comprises a lower shell, a reflective membrane is fixedly connected to the interior of the lower shell, an upper shell is fixedly connected to the top of the lower shell, and an embedding groove is formed in the inner top wall of the upper shell. And an image sensor is fixedly connected to the interior of the caulking groove. According to the novel differential pressure sensor, through the mutual cooperation of the lower shell, the reflective membrane, the upper shell, the image sensor, the data processing circuit board, the laser transmitter and the pressure interface, the effect of preventing the differential pressure sensor from interfering peripheral electronic products while the differential pressure sensor is prevented from being interfered by external electromagnetic interference is achieved; the differential pressure sensor solves the problems that an existing differential pressure sensor is poor in anti-electromagnetic interference capacity, prone to being subjected to external electromagnetic interference, prone to causing electromagnetic interference to surrounding electronic products and difficult to use in an electromagnetic field sensitive occasion.
Description
technical field [0001] The invention relates to the technical field of differential pressure sensors, in particular to a novel differential pressure sensor. Background technique [0002] At present, differential pressure sensors generally use the variation of capacitance, resistance or frequency to represent the pressure. This type of sensor has poor resistance to electromagnetic interference and is easily affected by electromagnetic interference to affect the output accuracy, and the work of the sensor itself will also affect other surrounding electronics. Products cause interference, so existing differential pressure sensors are not suitable for use in electromagnetic field sensitive applications. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a new type of differential pressure sensor, which has the advantages of preventing the differential pressure sensor from interf...
