Abstract
Provided is a dynamic pressure sensor. The dynamic pressure sensor comprises a base, an electrode and a pressure transmission plate. The top of the base is connected to the pressure transmission plate through an installation frame, the base is connected with the electrode through insulation coils, a piezoelectric plate a and a piezoelectric plate b are arranged on the upper side and the lower side of the electrode respectively, the electrode penetrates through the base to be connected with an electrode leading head, the pressure transmission plate is made of stainless steel, and the electrode is a glassy carbon electrode. The dynamic pressure sensor has the advantages of being simple in structure and convenient to manufacture and produce. In addition, dynamic acting force can be reflected accurately and instantly in the use process, the inaccurate measurement phenomenon is avoided, and therefore, the dynamic pressure sensor is easy to popularize.
Description
Technical field
The present invention designs a kind of pressure transducer, especially a kind of dynamic pressure transducer.
Background technology
Mechanics sensor of a great variety, as resistance strain gage pressure transducer, semiconductor gauge pressure transducer, piezoresistive pressure sensor, inductance pressure transducer, capacitance pressure transducer, resonance type pressure sensor and capacitance acceleration transducer etc.When understanding piezoresistive force sensor, first we be familiar with this element of resistance strain gage.Resistance strain gage is a kind of Sensitive Apparatus strain variation on measured piece being converted into a kind of electric signal.It is one of chief component of pressure resistance type strain transducer.What resistance strain gage application was maximum is metal resistance strain gauge and semiconductor gauge two kinds.Metal resistance strain gauge has again thread foil gauge and metal foil-like foil gauge two kinds.Normally being bonded in closely by special bonding agent by foil gauge produces on mechanics strain matrix, when the stressed generation STRESS VARIATION of matrix, resistance strain gage also produces deformation together, and the resistance of foil gauge is changed, thus makes to be added in ohmically voltage and change.The change in resistance that this foil gauge produces when stressed is usually less, and general this foil gauge all forms strain bridge, and is amplified by follow-up instrument amplifier, then is transferred to treatment circuit (normally A/D conversion and CPU) display or topworks.
Traditional pressure transducer is difficult to dynamic acting force immediately to reflect, and this just brings larger trouble to measurement, and the technology being therefore badly in need of a kind of improvement solves above-mentioned technological deficiency.
Summary of the invention
The invention provides a kind of dynamic pressure transducer.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
