Description
Technical field
The utility model relates to bunker scale exerciser simulated calibration field, is particularly a kind of easy to use, the portable bunker scale exerciser simulated calibration device that precision is high.
Background technology
The technique bunker scale that modern industry is used in producing, damaging and parameter Loss often appears in its exerciser, and replacing exerciser and Reparametrization will carry out bunker scale and demarcate calibration operation, and exerciser just can be made normally to show weight of material.But this work takes time and effort and delays normal production very much, due to technique bunker scale capacity comparatively large (generally at tens tons to hundreds of ton), mostly be the factor such as airtight container, installation site, therefore staking-out work is more difficult.So the technique bunker scale in modern industry production all adopts evaluation method to demarcate, although substantially can meet production requirement, this method error is large, to requiring that higher technique bunker scale is not suitable for.If want Accurate Calibration just must demarcate with counterweight, and be the work taken time and effort very much with counterweight demarcation, first the large counterweight amount that needs of bunker scale capacity is large, must use hoisting device.Secondly hopper scale installation site impact, narrow space, hoisting device operational difficulties.Have because of bunker scale reasons in structure again, place counterweight very difficult.And it is longer to demarcate a time, sometimes needs repeatedly to demarcate several times, have a strong impact on normal production.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy to use, the portable bunker scale exerciser simulated calibration device that precision is high, solve the problem that technique bunker scale exerciser damages or demarcates difficulty after parameter loss, contrast estimation standardization is in the past more accurate.
The utility model realizes like this, a kind of portable bunker scale exerciser simulated calibration device, comprise resistance R1, resistance R2, resistance R3 and adjustable potentiometer RP, wherein, resistance R1, resistance R2 is identical with resistance R3 resistance, the maximum value of adjustable potentiometer RP and resistance R1, resistance R2 is identical with resistance R3, be in parallel with the resistance R3 connected and adjustable potentiometer RP after resistance R1 connects with resistance R2, feeder ear draws two terminals for external power supply, draw respectively as signal end between resistance R1 and resistance R2 and between resistance R3 and adjustable potentiometer RP, the LOAD CELLS input end of bunker scale exerciser is connected at signal end, and be connected in parallel voltage indicator gauge.
Described voltage indicator gauge is millivolt step voltage table.
Further, the maximum range of resistance R1, resistance R2, resistance R3 and adjustable potentiometer RP is 600 ~ 800 Ω.
Compared with prior art, beneficial effect is the utility model: the utility model solves the problem that technique bunker scale exerciser damages or demarcates difficulty after parameter loss easily, and contrast estimation standardization is in the past more accurate.Through practice test, production requirement can be met completely.The utility model method is very easy to use, is easy to carry.Only need the extension line one_to_one corresponding of handle to receive on the terminal of bunker scale exerciser, by adjusting knob and calculating, bunker scale exerciser can be demarcated.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See Fig. 1 composition graphs 2, a kind of portable bunker scale exerciser simulated calibration device, comprise resistance R1, resistance R2, resistance R3 and adjustable potentiometer RP, wherein, resistance R1, resistance R2 is identical with resistance R3 resistance, the maximum value of adjustable potentiometer RP and resistance R1, resistance R2 is identical with resistance R3, be in parallel with the resistance R3 connected and adjustable potentiometer RP after resistance R1 connects with resistance R2, feeder ear 1 draws two terminals for external power supply, draw respectively between resistance R1 and resistance R2 and between resistance R3 and adjustable potentiometer RP as signal end 2, the LOAD CELLS input end of bunker scale exerciser is connected at signal end 2, and be connected in parallel voltage indicator gauge.After feeder ear 1 making alive, adjustment precision potentiometer signal end can export the millivolt voltage of analog sensor.

The maximum range of resistance R1, resistance R2, resistance R3 and adjustable potentiometer RP is 600 ~ 800 Ω.
Adopt the scaling method of above-mentioned portable bunker scale exerciser simulated calibration device, comprise following step:
(1) first LOAD CELLS is checked before demarcating;
(2) the supply source voltmeter according to the parameter in weighing sensor famous brand and exerciser calculates millivolt number per ton, millivolt number per ton=supply source voltage * transducer sensitivity/sensor rated capacity;
(3) with digital voltmeter measure bunker scale unloaded time LOAD CELLS output voltage values as bunker scale zero-point voltage value;
(4) LOAD CELLS and exerciser are separated from, replaced by calibration device LOAD CELLS to access in loop, the feeder ear of calibration device accesses the feed circuit of former LOAD CELLS, signal end is connected the LOAD CELLS input end of bunker scale exerciser;
(5) the adjustable potentiometer RP of calibration device is regulated, displayed value is adjusted to bunker scale zero-point voltage value, this value is converted into corresponding gravimetric value, gravimetric value=calibration device displayed value/millivolt number per ton), in the Zero calibration program of this gravimetric value input bunker scale exerciser, bunker scale exerciser Zero calibration is completed;
(6) any one gravimetric value of 80% to 100% of bunker scale max cap. is got, millivolt number per ton is multiplied by with this gravimetric value, be scaled a millivolt magnitude of voltage, then the adjustable potentiometer RP of calibration device is regulated to make calibration device show this value, in the range designation program of the gravimetric value input exerciser got above, complete the work of bunker scale exerciser range designation, finally bunker scale and exerciser circuit are recovered.
