Description

A kind of novel electron balance sensor

Technical field

The utility model relates to a kind of sensor, relates in particular to a kind of novel electron balance sensor.

Background technology

In the prior art, sensor is a kind of pick-up unit, can experience measured information, and the information that detection can be experienced, be for conversion into the information output of electric signal or other desired forms according to certain rules, to satisfy requirements such as transmission of Information, processing, storage, demonstration, record and control, it is a primary link of realizing detection automatically and automatic control.

Sensor application is in wide spectrums such as commercial production, space development, hydrospace detection, environmental protection, resource exploration, medical diagnosis, bioengineering, and almost the construction of modernized project all be unable to do without various sensors.

What be used for generally that sensor on the electronic balance uses is electromagnetic force balance sensor, its feature is to measure the gravity of counterweight when measuring the quality of testee, it is that the principle that adopts the gravity of electromagnetic force and testee to balance each other is measured, the scale pan is connected with coil by rack rod, in range of weighing, when the gravity mg of tested weight acts on the coil by connecting rod rack, direction upwards, at this moment in magnetic field if there is electric current to pass through, coil will produce an electromagnetic force F, can be represented by the formula:

F＝KBLI

Wherein K is constant (relevant with applying unit), and B is a magnetic induction density, and L is the length of winding wire, and I is the strength of current by winding wire.Testee gravity mg equal and opposite in direction, direction reach balance mutually on the contrary on electromagnetic force F and the scale pan, make scale pan support be returned to original position under the effect of elastic spring simultaneously.That is:

F＝KBLI＝mg

By following formula as can be known, be in the hot-wire coil in the magnetic field, its inner electric current I of flowing through is directly proportional with the quality of testee, as long as measure the quality m that electric current I is promptly known object.

But because balance in use, its sensor and circuit be temperature influence and working time variable effect in the course of the work, also be subjected to Effect of Environmental such as air-flow, vibration, electromagnetic interference (EMI), the capital makes electronic balance produce drift, cause measuring error, we must manage this influence is reduced to minimum level, are suppressed.

The utility model content

The purpose of this utility model provides a kind of novel electron balance sensor, uses it can reduce the influence that surrounding enviroment cause its measurement greatly, and measuring error is reduced.

To achieve these goals, the technical solution adopted in the utility model is: a kind of novel electron balance sensor, comprise base, the scale pan, wherein: described base comprises housing, integrated circuit modules, the magnet steel body, described integrated circuit modules is connected by lead with the magnet steel body, links to each other with a power supply again, is installed in the described housing, described housing outer surface is provided with LCDs, described base is connected with the described scale pan, is connected with an elastic body on the described scale pan, also is fixedly connected with a casing on the described base.

Above-mentioned novel electron balance sensor, wherein: described housing is plastic.

Above-mentioned novel electron balance sensor, wherein: the described scale pan is made of iron.

Above-mentioned novel electron balance sensor, wherein: described casing is a rectangular parallelepiped.

Above-mentioned novel electron balance sensor, wherein: the left surface of described casing, right flank and upper surface all are equipped with handle.

Above-mentioned novel electron balance sensor, wherein: the left surface of described casing, right flank and upper surface are moving door.

Above-mentioned novel electron balance sensor, wherein: each face of described casing is a glass.

Above-mentioned novel electron balance sensor, wherein: be provided with strain ga(u)ge in the described elastic body.

Owing to adopted technique scheme, the good effect that makes it to have is: the utility model is by a fixedly connected glass casing on electronic balance, whole device can be tested under the environment of sealing, reduce the influence that surrounding enviroment cause measurement, thereby reduce measuring error, degree of accuracy is improved greatly, the utility model compact conformation, easy to assembly, accurate positioning, good mechanical property.
