Secondly, referring also to DE102007002221A1 patent documents, including by detection magnetic field intensity progress position
Detection, using band extremely to dynamic magnetic and two Magnetic Sensors.
So far, people detect machine process equipment using the Magnetic Sensor of periodicity magnetic scale and length adaptation
In object, Magnetic Sensor detection magnetic direction or field strength.These Magnetic Sensors may be simply with reference to the fixed week of scale
Phase length uses.As alternative, moreover it is possible to, can be in the intersection measurement magnetic field side of x-component and y-component so using Magnetic Sensor
To/field strength, such as angular transducer.Generally, the Magnetic Sensor of length adaptation provided sinusoidal and cosine curve shape simulation letter already
Number.Using arc tangent interpolation method, by ASIC or μ controllers, positional value is determined.Profile distribution curve can be tight to a certain extent
The geometry of scale is limited to again, and such as bar is long or chi is thick.This just significantly reduces identified position to a certain extent
The precision of value.
Utility model content
The purpose of this utility model is, there is provided a kind of sensor device, the demand of user is adapted to by catering to it, should
Sensor device can realize the raising of measurement accuracy.Remain to self-supporting after sensor device experience longer time and need not tie up
Repair maintenance.
The utility model is a kind of sensor device to reach the solution of above-mentioned purpose, for detecting machining
Object in equipment, wherein the first Magnetic Sensor is arranged in housing, wherein, another magnetic sensing is there also is provided in housing
Device, and the distance of the first Magnetic Sensor to another Magnetic Sensor adapts to the scale of scale used.
The utility model is so achieved to reach the solution of above-mentioned purpose, i.e., is arranged in sensor device
First Magnetic Sensor and another Magnetic Sensor, such as TMR sensor, AMR sensor or GMR.It preferably, there are permanent magnetism
Body.
Included according to the sensor device of the present utility model for being used to detect the object in machine process equipment in housing
First Magnetic Sensor.In addition, another Magnetic Sensor is there also is provided in the housing.First Magnetic Sensor is to another magnetic
The distance of sensor adapts to the scale of used scale.This specifically represents that the scale includes cyclic magnetization scale.
TMR sensor (tunnel magnetoresistive) itself has stronger output signal, without again amplifying the signal.It is described
TMR sensor has high stability, only consumes few electricity, and has sine and cosine for angle detecting defeated respectively
Go out.In addition, when the size of gaps between the magnetic scale and the sensor is varied from, the fault-tolerance of height be present.
This point can realize flexible application.
When air gap of the AMR sensor (anisotropic magnetoresistive sensor) between sensor and magnetic scale is also relatively large
Equally there is very high measurement accuracy.Power consumption is low, at the same time, even if under the temperature fluctuation between -40 DEG C to+150 DEG C
Also complete feature can be given.The path difference of magnetic hysteresis can be neglected.AMR sensor include two wheatstone measurement bridges and
It is same to include the output of sinusoidal and cosine.
In addition, according to the requirement of measurement, GMR (giant magnetoresistance) also can be used.Other reluctance methods are different from, herein
Mode of operation be that electron spin effect is used in ultra-thin hierarchical system, and this effect changes transmission mechanism
Become.
On pending measurement there is which requirement and which measuring condition to be applicable depending on user, will be corresponding best
Magnetic sensor type is used in sensor unit.In this case, each magnetic sensing is also determined by user-defined mode
The distance that device can be limited individually between each other.
The Magnetic Sensor is arranged to the specific range being apart defined by the user to each other.By using more than one magnetic
Sensor, compared with only having the system of a Magnetic Sensor, measurement accuracy significantly improves.In addition, TMR, AMR or GMR
Great cost benefit and only need seldom electricity.
Distance of the Magnetic Sensor in the sensor device can be 0.5mm between 50mm.The distance is individually
Determined according to the preset need of user and requirement.By arranging that the first Magnetic Sensor and another magnetic sense with specific range
Device, different magnetic scales can be reflected.For example, by the orientability of the mutual distance of the Magnetic Sensor,
In addition to the metric system system, British and America system gauging system can also be taken into account.Easily missed here, can save remove in most cases
The conversion of difference.According to scale, the sensor device being individually adapted to is used.
In addition to the first Magnetic Sensor and another Magnetic Sensor, display is also integrated with the sensor device.Really
For cutting, first Magnetic Sensor and another Magnetic Sensor are arranged in housing.The display is LCD.Its is favourable
Part is that LCD costs are cheap, power consumption is few and working stability.
In addition, the sensor device also includes display electronic device, it changes the data transmitted from the Magnetic Sensor
It is counted as the value shown on the display.
The magneto-dependent sensor, the display electronic device and the display fill with being equally integrated in the sensor
The battery of commercial standard (CS) in putting is connected.Which guarantee power supply of the listed component within the several years.Thus volume need not be set
Outer power supply.Which simplifies the installation and removal in machining equipment and enable sensor device self-sufficient.
The sensor unit be easy to assembling, manufacturing cost it is cheap and be easy to be installed in machining equipment and
Dismounting.In this case, the most long activity duration depends on the power of integrated battery.Because the sensor device be advantageous to production and
It is compact-sized but close, therefore and be not provided with change battery scheme.
If the power drop of the battery, this case is passed on via the display.Because cost is cheap and compact
Make, then just change whole sensor device.
Borrow this according to sensor device of the present utility model, it can be ensured that continuous self-sufficiency interior for many years, need not repair and protect
Foster, independent adaptation and reliable and stable feature.
The Magnetic Sensor being respectively adopted in the sensor device has identical channel, this expression, exists with phase
With the signal in magnetic induction direction.Here, without carrying out different adjustment or conversion again.Thus measurement accuracy is improved, is not in
Conversion error.
The signal of the Magnetic Sensor is in 90 ° of phase shifts, and this expression, a quarter of the Cycle Length of sensor signal is present
Skew.
Comparatively, the whole power consumption of the sensor device is extremely low because employ such as TMR, AMR and/
Or μ C and/or ASIC in the low power sensor and CMOS technology of GMR, and the display is energy-saving
Liquid crystal display (LCD).Thus, the sensor device being individually adapted to also great cost benefit and is easily changed.
