Compared with the prior arts, the two-channel weighing sensor and a weighing system applying the same have the advantages of having a two-channel signal output function, being convenient to realize the function for tandem scale-assembling, having no requirement for intermediate transition of a junction box, reducing the connection cost for a weighing device, and improving the reliability.
Description
Technical field
The utility model relates to a kind of LOAD CELLS, and the utility model also relates to a kind of weighing system.
Background technology
At present, column type sensor is widely used in various electronic-weighing equipment such as various truck scales, track scale, axle weight scale, batch can scale.Column type sensor generally comprise pillar elastic body, be positioned at the elastic body outer wall housing, be located at strainometer, A/D modular converter hardware circuit and application software on the elastic body.Conventional housing is shaped for metal pipe material machining, and profile is relatively poor, and is of low grade; But processing cost is very high; During use, conventional column type sensor all need be wired to the terminal box transfer, connects to form weighing-appliance with instrument again; And find in using that the terminal box failure rate is very high, and link cost higher be the weak link of weighing-appliance.
The utility model content
Thereby the utility model technical matters to be solved is that a kind of binary channels LOAD CELLS of being convenient to realize connecting link cost being reduced is provided to the above-mentioned state of the art.
The utility model technical matters to be solved provides low, the rakish binary channels LOAD CELLS of a kind of cost.
Thereby the utility model technical matters to be solved provides a kind of weighing system of being convenient to realize connecting link cost being reduced.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of binary channels LOAD CELLS; Comprise that the elastic body of pillar, the housing that is positioned at the elastic body outer wall, the strain of being located on the elastic body take into account the data-converting block that is connected with strainometer; It is characterized in that described data-converting block is the two-channel digital modular converter, and described elastic body is outward extended with first passage joint and second channel joint through this data-converting block.
Further, described data-converting block comprises A/D modular converter hardware circuit and corresponding application software.
Further, described first passage joint and second channel joint all are equipped with aviation plug.
Described housing is an integrated punching spare, and this housing and elastic body are that argon arc is welded.Housing is the drawing structure, and is handsome in appearance, and cost is low.
A kind of weighing system of binary channels LOAD CELLS is characterized in that comprising weighing instrument and a plurality of binary channels LOAD CELLSs of connecting each other successively, and two adjacent binary channels LOAD CELLSs are connected through following mode:
The first passage joint of the binary channels LOAD CELLS of front is connected with the first passage joint of back binary channels LOAD CELLS;
Perhaps, the second channel joint of the binary channels LOAD CELLS of front is connected with the second channel joint of back binary channels LOAD CELLS;
And the first passage joint of last binary channels LOAD CELLS is connected with the first passage joint of the binary channels LOAD CELLS of front, and the second channel joint is connected with the input end of weighing instrument.
Compared with prior art, the advantage of the utility model is: the utlity model has the double-channel signal output function, can realize series scale function easily, need not the terminal box middle transition, reduced the link cost of weighing-appliance, improved reliability simultaneously again.
