The invention discloses a pressure sensor, which comprises a pressure sensing transmission unit, a threaded mechanical interface and a casing independent of each other, the threaded mechanical interface and the casing are fixed together, the threaded mechanical interface is connected to the The pressure sensing transmission unit is connected, the threaded mechanical interface is composed of a bolt, a second cylinder and a first cylinder connected in sequence, the diameter of the second cylinder is smaller than the diameter of the first cylinder, the bolt, the first cylinder The two cylinders and the first cylinder are integrally constructed, the bolts are provided with blind holes along the central axis, and the first cylinder is connected to the pressure induction transmission unit. The threaded mechanical interface of the pressure sensor of this structure is composed of bolts connected in sequence, the second cylinder and the first cylinder in one piece, which not only has a simple structure, but also can greatly reduce the production cost of the pressure sensor.
Description
Technical field [0001] The invention relates to an industrial sensing component, in particular to a pressure sensor. Background technique [0002] The pressure sensor is the most commonly used sensor in industrial practice, and the pressure sensor we usually use is mainly manufactured by the piezoelectric effect. Such a sensor is also called a piezoelectric sensor. We know that crystals are anisotropic and non-crystals are isotropic. Certain crystal media, when deformed by mechanical force in a certain direction, will produce polarization effect; when the mechanical force is removed, it will return to the uncharged state, that is, when under pressure, a certain These crystals may produce electrical effects, which is the so-called polarization effect. Scientists have developed a pressure sensor based on this effect. [0003] Of course, there are many types of pressure sensors, such as resistance strain gauge pressure sensors, semiconductor strain gauge pressure sensors, piezoresi...
