Technical field
The utility model relates to a kind of sensing equipment, particularly a kind of fluid level transmitter that is applied to the large-scale liquid storage tank level gauging.
Background technology
Along with the development of Chemical Engineering Technology, measure sensing technology and play more and more important effect in Industrial Engineering.In the level gauging technology, thereby often need sensor to draw current liquid reserves by the pressure of measuring liquid.Piezoelectric sensor is the sensor that utilizes the piezoelectric effect that produces after some dielectric medium stress to make.So-called piezoelectric effect refers to that some dielectric deformation occurs when (comprising bending and telescopic shape change) at the External Force Acting that is subject to a direction, due to the polarization phenomena of internal charge, can produce on its surface the phenomenon of electric charge.Piezoelectric can be divided into piezoelectric monocrystal, piezoelectricity polycrystalline and organic piezoelectric materials.With the most use in piezoelectric transducer is to belong to all kinds of piezoelectric ceramics of piezoelectricity polycrystalline and the quartz crystal in piezoelectric monocrystal.When sensor is output as the specified standard signal, be called transmitter.
In prior art, the fluid level transmitter that large-scale liquid storage tank uses does not often have explosion prevention function, and volume is larger simultaneously, and is relatively poor with the sealing property of tank body.The transmitter that those skilled in the art develops urgently a kind of piezoelectric sensor and uses it solves the problems referred to above.
The utility model content
The technical problems to be solved in the utility model is for overcoming in prior art, and fluid level transmitter does not have explosion prevention function, and sealing is poor, and the deficiencies such as unreasonable structure provide a kind of fluid level transmitter.
The utility model solves above-mentioned technical matters by following technical proposals:
A kind of fluid level transmitter, its characteristics be, described fluid level transmitter comprises:
