#回憶
#eflection是當載荷為從零增加到標稱值傳感器的測量原理
傳感器的測量原理基于Pressductor?技術和以下事實：磁性材料的磁導率在機械應力下變化。
傳感器由一堆經(jīng)過特殊處理的層壓板組成，構成測量體。初級和次級繞組通過傳感器中的四個孔纏繞，以便它們在直角。
初級繞組被提供交流電流，從而在其周圍形成磁場
初級繞組。由于兩個繞組相互成直角，只要傳感器上沒有負載，次級繞組周圍就不會有磁場。
當傳感器在測量方向上受到機械力時，磁場的傳播發(fā)生變化，從而包圍次級繞組，在該繞組中感應交流電壓。
控制單元將該交流電壓轉(zhuǎn)換為與施加的電壓成比例的直流電壓
武力如果測量力改變方向，傳感器信號也會改變極性

Working temperature range
Working temperature range is the temperature range within which the load cell can operate within
a specified accuracy. The maximum permitted temperature drifts (i.e. zero point and sensitivity
drifts) of the load cell are not necessarily maintained in the whole working temperature range.
Storage temperature range
Storage temperature range is the temperature range within which the load cell can be stored.
Zero point drift with temperature
Zero point drift is defined as the signal change with temperature, related to the sensitivity, when
there is zero load on the load cell.
Sensitivity drift with temperature
Sensitivity drift is defined as the signal change with temperature at nominal load, related to the sensitivity, excluding the zero point drift.
#eflection
#eflection is the total deformation in the measuring direction of the load cell when the load is
increased from zero to the nominal value
Measuring principle of the sensor
The measuring principle of the sensor is based on the Pressductor? technology and the fact that
the permeability of a magnetic material changes under mechanical stress.
The transducer is made up of a stack of specially treated laminates, forming the measuring body.
Primary and secondary windings are wound through four holes in the sensor so that they cross at
right angles.
The primary winding is supplied with an alternating current which creates a magnetic fieKd around
the primary winding. Since the two windings are at right angles to each other, there will be no magnetic fieKd around the secondary winding, as long as there is no load on the sensor.
When the sensor is subjected to a mechanical force in the direction of measurement, the propagation of the magnetic fieKd changes so that it surrounds the secondary winding, inducing an alternating voltage in that winding.
The control unit converts this alternating voltage into a DC voltage proportional to the applied
force. If the measurement force changes direction, the sensor signal changes also polarity
Mounting Arrangement
When choosing a mounting arrangement it is important to remember to position the load cell in a
direction that gives sufficient measuring force (FR) to achieve the highest possible accuracy.
The load cell has no particular correct orientation; it is positioned in the orientation best suited for
the application, bearing in mind the positions of the screw holes. The load cell can also be installed
with the roll suspended under the load cell.
