Technique for early diagnosis of lots cell "sub-health".<br>
[Abstract] This short article introduces a principle and method of precise and early diagnosis of the "sub-health" condition of lots cells.

[Keyword phrases] early; medical diagnosis; "sub-health"; tons cell; technique.

I. Introduction.

With the continuous growing of enterprise technical transformation, electronic considering instruments have been made use of an increasing number of commonly in process circulation, process control, as well as settlement and measurement. The resistance pressure type tons cell (hereinafter referred to as the sensing unit) is a type of steel elastic body as the force.

- Measuring tools with electric conversion feature, and sensing units are the core parts of digital weighing instruments. As a result of the integral attributes of the sensor itself.

And in a complex and rough setting, its failings are identified by variety and intricacy, and the failure price is also higher. Present.

Changing the sensor in the area judgment will certainly not only influence the normal manufacturing rhythm, however also create the wind, the furnace, the faulty item and the failing to determine.

The amount, etc, seriously impact the financial advantages of the enterprise. Maintenance employees wish that there is a method to advance the sensor failure.

Obtain reminded.

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

" Sub-health") to boost the campaign of maintenance and accomplish the function of "zero failure" upkeep.

2. Principles and also phenomena.

The lots cell entails disciplines such as mechanics, electrical energy, and chemistry. The root cause of the mistake is made complex and it is challenging to court. Formation in failing.

It is without a doubt difficult to diagnose in advance that the lots cell remains in a "sub-healthy" problem.

The mistakes of the tons cell can be separated right into three categories according to the concept: A, triggered by elastic body; B, triggered by electric shock and circuit.

的; C, brought on by the pasting process. But no issue what sort of failings will certainly be reflected through the unbalanced result.

The dimension of the no factor result of the lots cell is a representation of the high quality of the production procedure as well as the top quality of the layout, and also it is likewise a possible failing.

One of the most noticeable symptoms.

The no factor outcome of the load cell is also big, which presents a potential danger to the reliability of the sensing unit. The change of zero point will likewise make.

On this basis, after expedition, it is found that the empty scale outcome and no-load output signal changes of the load cell. At the same time, it additionally describes the result of the vacant range. The change of the outcome of the vacant range is a concentrated representation of 2 essential technological signs of the lots cell absolutely no point as well as linearity.

The lots cell is in the "sub-healthy" condition. Both most usual as well as most sensitive sensations are the two most sensitive and usual attributes: one is that the considering indication typically alters no throughout usage, but it can automatically return to no without influencing the evaluating. hydraulic load cell is that when the conventional weight is loaded throughout the usage period, there is commonly a minor over-tolerance, however it can be restored to typical by changing the potentiometer. Among these phenomena shows that there are "sub-healthy" sensing units in the scale. Just how to detect and also locate?

1. Tracking.

( 1) Tracking of empty ranges with lots cells. Under real weighing problems, the load-bearing gadget considers the body (or load-bearing evaluating.

The frame) remains in area, and also the mechanical components remain in area. Action the output value of each sensor of the scale under the excitation voltage, and edit it by placement.


Great number, make a great document. This is the outcome value of the sensor's empty range.

( 2) No-load surveillance of the load cell. Under real considering problems, position each sensor of the scale.

No-load state, determine the outcome worth of each sensor under the excitation voltage, code the number according to the position, and also make a document. This is the transmission.

No-load result value of the sensing unit. At the exact same time, the input insusceptibility of the sensing unit is gauged, and the result insusceptibility and also the no-load outcome are compared to the technological specifications offered by the producer at the manufacturing facility.

( 3) After calibrating the scale and also loading with the typical weight, it is best to measure each of the scales under the problem of typical weight loading.

Just the output worth of the sensor, number it according to the position, make a document as well as indicate the common weight worth. This is the sensor's conventional weight result.

value.

2. Tracking.

Establish the time space of the following measurement according to the place of usage, celebration, atmosphere and also other conditions. For each and every sensing unit.

The vacant scale result (or typical weight result), no-load outcome for tracking dimension.

( 1) Make use of the manufacturing void to on a regular basis gauge the empty scale outcome as well as no-load output of each sensing unit of the scale.

The problems can gauge the common weight output of each sensor under the same conventional weight. Make a document and contrast it with the initial record.

( 2) When the sensor's vacant range result (or basic weight output) and also no-load result modification greatly, the monitoring time space must be.

Shorten, the monitoring density ought to be increased; when the result is secure for a long time, the tracking gap can be properly prolonged.

( 3) The same lots is compared on its own at various factors (areas) of the scale, and the tolerance is gone beyond, and also the vacant scale of each sensing unit is measured.

Output, no-load outcome, make a record, and also compare to the original document.

This approach is typically utilized under busy evaluating problems to recognize the operating condition of the range.

( 4) When the sensing unit's "sub-healthy" sensation appears, it is necessary to boost the outcome of the vacant scale monitoring each sensor (or.

Basic weight result) The measured density of no-load result, make a document, and also compare it with the initial record.

( 5) For digital sensing units, utilize the same method to enter the empty range internal code worth, empty inner code worth, and typical weight internal code worth.

Conduct monitoring and monitoring, and make good documents.



The lasting security of the no factor of the tons cell is a prerequisite technical index in the reliability as well as stability of the sensor. On this basis, after exploration, it is located that the vacant scale outcome as well as no-load result signal changes of the lots cell. At the very same time, it additionally describes the outcome of the vacant range. The change of the output of the empty scale is a focused representation of 2 essential technical signs of the tons cell zero point as well as linearity.

One of these sensations suggests that there are "sub-healthy" sensing units in the scale.
