Small make up popular science sets equipment sensor today, as the ceaseless development of industry of content couplet network, the important equipment it may be said that sensor regards content couplet net as to feel a layer is indispensable.

What is sensor

The mankind relies on 5 kinds of sense organs to feel environmental change, and sensor is equivalent to equipment " sense organ " . Those who say is a bit commonner, namely " can use this tool, measure this kind of thing " . Sensor detects the physics in the environment changes, and the real time condition the environment, signal of translate into electron is outputted.

Be aimed at flavour, odour, sound, vision, touch, the person has body of tongue, nose, ear, eye 5 great senses, regard content couplet net as the system in " sense organ " but sensor compares the mankind powerful much, the sort of sensor was to exceed the mankind more a lot of.

The main effect of sensor

People to get information from the outside, must have the aid of at sensory.

And what sheet relies on people oneself is sensory, their function in studying natural phenomenon and rule and manufacturing activity is far insufficient. To get used to this kind of circumstance, need sensor. Because this can say, sensor is the extension of human facial features, the facial features is report that says again.

The arrival of new technology revolution, the world begins to enter information period. In the process that uses information, what should solve above all is to should get accurate and reliable information, and the main avenue that sensor is the information in getting nature and manufacturing field and method.

Produce in modern industry especially in automation production process, monitor and should control each parameter in producing a course with all sorts of sensor, make facility work is in whack or groove, make the product reachs best mass. Because this can say, without numerous admirable sensor, modern production also lost a base.

In fundamental course research, sensor has prominent place more. The development of modern science and technology, entered a lot of new fields: Be in for example macroscopical on the boundless and indistinct universe that wants on observation 1000 light-year, microcosmic on should observe small the particle world to Fm, even if want observation to be as long as up the celestial body evolution of tens of all ages, short react to the instant of S. In addition, still appeared to be known to deepening material, develop all sorts of new energy resources, new material extreme technology research that have main effect, like superhigh temperature, ultralow temperature, superhigh pressure, ultrahigh vacuum, super- strong magnetic field, exceed weak magnetic field etc. Apparent, want to get the information that many mankind sense organ cannot get directly, the sensor that did not suit is impossible. The obstacle that a lot of background science study, get existence difficulty with respect to what depend on target information above all, and a few new mechanism detect with what Gao Lingmin spends of sensor appear, often can bring about the breakthrough inside this domain. The development of a few sensor, often be the pioneer that course of a few brims develops.

How to choose sensor

To how choosing sensor, the detail that needs a consideration has a lot of, want to consider to be measured what data suits most to measure a principle not only, should consider the particular function target of sensor more.

Sensitivity

It is commonly inside the linear limits of sensor, the sensitivity of hope sensor has been jumped over higher. But also ask sensor itself should have taller letter a confusion of voices to compare at the same time, reduce the interference signal that introduces from the outside as far as possible.

Stability

After sensor uses period of time, its function maintains changeless ability to call stability. The element of long-term stability divides influence sensor outside sensor itself structure, basically be the use environment of sensor. Accordingly, want to make sensor has good stability, sensor must want to stronger environment gets used to ability.

Precision

Precision is a of sensor main function index, it is to matter to whole a when measure a system to measure precision important segment. The precision of sensor is taller, its price is higher, accordingly, the precision of sensor should be satisfied only whole the precision demand that gauges a system is OK, need not choose exorbitantly.

Linear limits

The linear range of sensor is wider, criterion its span is bigger, and can assure certain measurement precision. When choosing sensor, want to see its span whether satisfy a requirement above all later certainly when the sort of sensor.

Frequency answers character

Actually of sensor answer always have, calm defer, it is better to hope defer time is shorter. The frequency of sensor is answered taller, the signal frequency range that can measure is wider.

Net of couplet of the content that believe acute solution, be aimed at familiar sight, be like: The setting such as classroom, office, assembly room, computer room, can offer most the common sensor of use demand of setting of press close to. Besides the sensor of brand of the oneself that believe acute, platform of net of couplet of the content that believe acute has the character of open sex more, supportable of sensor of many kinds of tripartite receive, match from what receive a safeguard to send feeling equipment gender and professional, comprehensive implementation user accepts the demand of layer base facilities to setting of content couplet net. ? ? ? ?
