Method for very early medical diagnosis of load cell "sub-health".<br>
[Abstract] This post introduces a principle as well as method of very early and exact diagnosis of the "sub-health" condition of lots cells.

[Key phrases] early; medical diagnosis; "sub-health"; tons cell; approach.


I. Introduction.

With the continual strengthening of enterprise technological change, digital weighing instruments have actually been utilized more and extra commonly in process circulation, procedure control, as well as negotiation and also dimension. The resistance strain type lots cell (hereinafter referred to as the sensing unit) is a sort of metal elastic body as the force.

- Measuring instruments with electrical conversion feature, as well as sensors are the core elements of electronic considering instruments. As a result of the inherent attributes of the sensing unit itself.

As well as in a complicated and also severe setting, its failures are defined by diversity and complexity, and also the failure rate is also greater. Existing.

Changing the sensor in the area judgment will not just impact the normal manufacturing rhythm, but also trigger the wind, the heating system, the faulty product as well as the failure to compute.

The quantity, etc, seriously affect the economic advantages of the venture. Upkeep personnel wish that there is a means to progress the sensing unit failing.

Get reminded.

After years of exploration, there is a way to precisely identify whether the lots cell is poor or otherwise (abbreviated as.

" Sub-health") to boost the effort of maintenance as well as accomplish the objective of "absolutely no failure" upkeep.

2. Principles and also sensations.

The load cell entails disciplines such as auto mechanics, electrical energy, as well as chemistry. The source of the mistake is made complex and it is challenging to court. Development in failure.

It is indeed hard to identify beforehand that the load cell is in a "sub-healthy" problem.

The faults of the lots cell can be split right into 3 categories according to the principle: A, triggered by flexible body; B, triggered by electrical shock as well as circuit.

的; C, caused by the pasting procedure. No matter what kind of failures will certainly be reflected with the unbalanced outcome.

The dimension of the zero factor output of the load cell is a representation of the quality of the manufacturing process and the top quality of the design, and also it is likewise a possible failure.

Among one of the most obvious symptoms.

The zero factor output of the load cell is also big, which postures a possible danger to the dependability of the sensing unit. The adjustment of zero point will certainly also make.

On this basis, after exploration, it is located that the empty scale result as well as no-load result signal adjustments of the load cell. At the very same time, it also discusses the outcome of the vacant range. The adjustment of the result of the vacant scale is a concentrated reflection of two important technical signs of the load cell absolutely no factor and linearity.

The tons cell is in the "sub-healthy" condition. One of these phenomena shows that there are "sub-healthy" sensing units in the range.

1. Surveillance.

( 1) Surveillance of vacant ranges with tons cells. Under actual evaluating problems, the load-bearing device weighs the body (or load-bearing evaluating.

The framework) is in area, and the mechanical components are in place. Action the outcome value of each sensor of the range under the excitation voltage, as well as edit it by position.

Great number, make a great document. This is the output worth of the sensing unit's vacant scale.

( 2) No-load tracking of the load cell. Under actual considering conditions, put each sensing unit of the range.

No-load state, determine the outcome value of each sensing unit under the excitation voltage, code the number according to the position, as well as make a record. This is the transmission.

No-load outcome value of the sensing unit. At the exact same time, the input resistance of the sensing unit is measured, as well as the result insusceptibility as well as the no-load output are contrasted with the technical specs provided by the producer at the manufacturing facility.

( 3) After loading as well as adjusting the scale with the basic weight, it is best to measure each of the scales under the condition of basic weight loading.

Only the output worth of the sensor, number it according to the setting, make a record and also indicate the conventional weight worth. This is the sensor's standard weight outcome.

value.

2. Tracking.

Establish the time void of the next measurement according to the area of use, occasion, setting as well as other problems. For load cell "kubota" .

The empty scale output (or standard weight output), no-load result for tracking dimension.

( 1) Make use of the production gap to routinely measure the vacant scale outcome and no-load outcome of each sensor of the range.

The conditions can measure the standard weight result of each sensor under the very same common weight. Make a record as well as contrast it with the original record.

( 2) When the sensor's vacant scale result (or typical weight outcome) as well as no-load result change considerably, the monitoring time space should be.

Shorten, the monitoring thickness ought to be enhanced; when the output is steady for a long period of time, the tracking gap can be properly extended.

( 3) The exact same lots is compared on its own at various factors (sections) of the range, and the tolerance is surpassed, as well as the vacant range of each sensing unit is measured.

Result, no-load outcome, make a record, as well as compare with the initial record.

This approach is commonly made use of under fast-paced weighing problems to comprehend the operating condition of the scale.

( 4) When the sensing unit's "sub-healthy" phenomenon shows up, it is needed to enhance the result of the empty range tracking each sensing unit (or.

Basic weight result) The gauged density of no-load result, make a record, as well as contrast it with the original record.

( 5) For electronic sensors, make use of the exact same approach to get in the empty scale inner code worth, empty inner code value, and standard weight interior code value.

Conduct monitoring and monitoring, and make excellent records.



The lasting stability of the absolutely no factor of the tons cell is a requirement technical index in the dependability and also stability of the sensing unit. On this basis, after exploration, it is located that the empty range result as well as no-load result signal changes of the lots cell. At the same time, it additionally explains the output of the empty range. The modification of the result of the vacant scale is a concentrated representation of 2 important technical indicators of the tons cell absolutely no point as well as linearity.

One of these phenomena suggests that there are "sub-healthy" sensors in the range.
