Abstract
The invention discloses a pressure transmitter with stronger overload resistance capability, comprising a ceramic sensor, an intelligent electronic circuit and a communicator, wherein the ceramic sensor directly contacts with a measured medium to sense pressure and generate pressure displacement amount; the intelligent electronic circuit is used for detecting the pressure displacement amount of the ceramic sensor and converts the pressure displacement amount into a standard industrial measuring signal; and the communicator is used for receiving and outputting the obtained standard industrial measuring signal. The pressure transmitter with stronger overload resistance capability has the advantages of improving the overload resistance capability of the pressure transmitter and enhancing the reliability of instruments.
Description
Technical field
The present invention relates to a kind of pressure unit.
Background technology
In most of pressure unit designs, between pressure transducer reaction diaphragm and pressure detection circuit, use intermediary's liquid to transmit the also variation of induction pressure, thereby obtain the pressure amount of moving and be converted into corresponding standard industry signal.But be to use the problem of intermediary's liquid to be, when pressure unit runs into overload situations or pressure differential when excessive, damage instrument and use to such an extent as to can make diaphragm that excessive displacement takes place, the user of service must its measurement environment of cautious investigation, can not transship guaranteeing.And this judgement and being not easy damages so this type of pressure unit uses under overload situations very easily.
Summary of the invention
Purpose of the present invention addresses the above problem exactly, makes that pressure unit also is not easy to damage under overload situations.For realizing this purpose, the invention provides the stronger pressure unit of a kind of anti-overload ability, it is characterized in that comprising:
Ceramic sensor element directly contacts measured medium, and induction pressure also produces the pressure amount of moving;
The smart electronics circuit detects the pressure amount of moving of ceramic sensor element, and is converted to the standard industry measuring-signal;
Communicator receives the standard industry measuring-signal and the output that are obtained.
Preferably, described ceramic sensor element, the distance between ceramic matrix and the diaphragm is between 0.06mm～0.09mm, and ceramic diaphragm directly is attached on the ceramic matrix during overload.
Preferably, described communicator has Man Machine Interface, can set the user requested data situation, comprises output unit, simulation range, output type, these several aspects of setting damping at least.
Preferably, described communicator can be used for calibrating sensors zero-bit and standard industry measuring-signal.
Preferably, also comprise accident warning device, export corresponding failure alarm signal when detecting the transmitter fault automatically.
The invention has the advantages that, do not use intermediary's liquid, simultaneously the distance between reaction diaphragm and ceramic matrix is less, makes that deformation was excessive when diaphragm can be owing to overload to damage, and has improved the ability of instrument shock resistance and overload.
Description of drawings
Fig. 1 has showed structural drawing of the present invention.
Embodiment
Embodiment one
See also Fig. 1, Fig. 1 is a structural drawing of the present invention.It mainly comprises ceramic sensor element, smart electronics circuit and communicator three parts.Wherein do not use intermediary's liquid between the diaphragm of ceramic sensor element and the ceramic matrix, both distances are between 0.06mm～0.09mm, and when running into impulsive force or overload, diaphragm can directly be affixed on the ceramic matrix, thereby strengthen the ability of diaphragm shock resistance and overload.The pressure of this ceramic sensor element of smart electronics wireline inspection moves quantitative changeization, and is converted into the standard industry signal and exports.Communicator has Man Machine Interface, can set the user requested data situation, comprises output unit, simulation range, output type, these several aspects of setting damping at least.Adjustable transducer zeroing and standard industry measuring-signal also comprise accident warning device simultaneously, export corresponding failure alarm signal when detecting the transmitter fault automatically.
The invention has the advantages that, improved the ability of pressure unit anti-impact force and overload, strengthened reliability of products and durability.
The invention provides a kind of pressure unit, especially the stronger pressure unit of anti-overload ability.Above embodiment is only in order to explanation, and unrestricted technical scheme of the present invention.Those of ordinary skill in the art is to be understood that: the present invention is made amendment or is equal to replacement, and do not break away from any modification or partial replacement of the spirit and scope of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
