Description

Sensor cluster

Technical field

This utility model relates to a kind of sensor cluster, a kind of sensor cluster being applied to strain chip.

Background technology

Pole structure LOAD CELLS is widely used to all kinds of electronic weighing appliance such as electronic vehicle weighing apparatus, track scale. The scale frame of weighing equipment is typically to be shelved on the pressure bearing head of multiple multi-faceted column weighting sensor, sensor Direct and weighing equipment the scale bridge joint in pressure bearing head upper surface touches.When weighing, scale frame always can first be rushed by side force Hit and certain horizontal displacement occurs, thus drive the inclination of column weighting sensor generation certain angle, thus The degree of accuracy of sensor can be affected, the most just make the precise decreasing of sensor, reduce the standard of weighing-appliance system Exactness.

Common LOAD CELLS can only realize weighing of a range specification, measures narrow range, for measuring model Enclosing wider industry and weigh occasion, when using the sensor measurement of wide range, the part of small-range is too small because of range And precision cannot meet requirement.

Utility model content

The purpose of this utility model is to provide a kind of certainty of measurement height and has multiple range sensor cluster.

According to an aspect of the present utility model, it is provided that a kind of sensor cluster, it includes first sensor, institute State first sensor to include the first fixing end, the first force side, the first force side and first are fixed end couple together The first parallel guiding connector and the first foil gauge, described sensor cluster also includes the second sensor, described First sensor include being fixed to the second fixing end of the first fixing end, the second force side, by the second force side and the Two fix the second parallel guiding connector and the second foil gauge that end couples together, and described sensor cluster also includes One end is fixed to the first force side, the other end extends to the stop part immediately below the second force side.

Preferably, described first sensor and the second sensor have identical longitudinal axis.

Preferably, the described first fixing end and the second fixing end are secured together by the way of welding.

Preferably, the mode that the described first fixing end and the second fixing end are fixed by screw is secured together.

Preferably, described stop part and the first force side are integral type.

Preferably, described stop part is fixed to the first force side by the way of assembling.

The sensor cluster that this utility model provides by arranging two sensors, can reach certainty of measurement high, Measurement has multiple range technique effect.

Accompanying drawing explanation

Being to be further understood from this utility model for providing including accompanying drawing, they are included and constitute the application's A part, accompanying drawing shows embodiment of the present utility model, and plays explanation this utility model together with this specification The effect of principle.In accompanying drawing:

Fig. 1 is the schematic diagram of sensor cluster of the present utility model.

Fig. 2 is schematic diagram during the second force acting on transducer.

Fig. 3 is the schematic diagram supporting on stop part during the second force acting on transducer.

Detailed description of the invention

With detailed reference to accompanying drawing, embodiment of the present utility model is described now.

Shown in Figure 1, this utility model is a kind of sensor cluster, and it includes first sensor 2.First passes Sensor 2 includes that first fixes end the 23, first force side 21, by the first force side 21 and the first fixing end 23 company The first parallel guiding connector 22 and the first foil gauge 24 picked up.Sensor cluster also includes the second sensing Device 3.First sensor 3 include being fixed to the second of the first fixing end 23 fix end the 33, second force side 31, Should by parallel with second that the second fixing end 33 couples together for the second force side 31 guiding connector 32 and second Become sheet 34.Sensor cluster also includes that one end is fixed to the first force side 21, the other end extends to the second force side Stop part 4 immediately below 31.

In the present embodiment, first sensor 2 and the second sensor 3 have identical longitudinal axis.At other In embodiment, the longitudinal axis of first sensor 2 and the second sensor 3 can also differ, the most misaligned setting.

First fixing end 23 and the second fixing end 33 are secured together by the way of welding.Other embodiment party In formula, the mode that the first fixing end 23 and the second fixing end 33 are fixed by screw is secured together.

Stop part 4 and the first force side 21 are integral type.In other embodiments, stop part 4 is by assembling Mode be fixed to the first force side 21.

Further regard to shown in Fig. 2 and Fig. 3, when power is applied on the second force side 31, the second force side 31 Move down.Second foil gauge 34 detects deformation and produces signal, for calculating the size exerted oneself.When power is big During to certain value, the second force side 31 supports on stop part 4, and then drives the first force side 21 to move down, Now, the first foil gauge 24 detects deformation and produces signal, the size in calculating.When power is little, The size exerted oneself can be calculated with the second foil gauge 34.When power is bigger, can be calculated by the first foil gauge 24 The size of power.This arranges and can reach have multiple range purpose.In other embodiments, can arrange more Sensor, to reach the setting of more range.

Skilled person will appreciate that, above-described embodiment of the present utility model is carried out various modifications and variations and Without departing from spirit and scope of the present utility model.Accordingly, it is intended to make this utility model cover in appended right In the range of claim and equivalent arrangements thereof to amendment of the present utility model and modification.
