Verification (Device Health Diagnosis) Function

How long does it take each device to carry out an equipment inspection?

It varies according to application and process, inspection item and worker skill.
ADMAG AXW offers the following three methods to easily diagnose the soundness of equipment.
It is available to choose the best diagnosis method according to the situation and the diagnosis you want to check.
Anyone can check the same item automatically.

Items Description
Built-in Verification Simple diagnostic function that can be executed by a single device.
Standard/Enhanced Verification More fundamental diagnostic function that utilizes FieldMate.
In addition, Enhanced Verification allows for more accurate diagnostics.

 

Built-in Verification Function (Our proprietary patented technology)

Built-in verification diagnoses the integrity of the transmitter and detector.
As the soundness of the converter, it diagnoses three items: “Calculation circuit”, “Device status (error history)” and “Connection status”.
We diagnose two of "magnetic circuit" and "excitation circuit" as soundness of the detector.
Then, based on the results of these five soundness diagnoses, the soundness of the entire device is diagnosed.

Built-in Verification Function (Our proprietary patented technology)

 

Standard Verification

In addition to the diagnostic content of the built-in verification function, the standard verification function can inspect the appearance of the chassis and display board, and diagnose the dot missing of the LCD.
In addition, since the diagnosis results can be output as A4 size PDF, they can be used as supplementary data for reporting and management of inspection history. To use the standard verification function, separately purchase the "FSA130 ADMAG TI Verification Tool".

Standard Verification

 

Enhanced Verification

The extended verification function can diagnose the soundness of current input / output, pulse output, transducer accuracy, and electrode insulation resistance by using external devices in addition to the standard verification diagnostic contents.
In addition, manual input of the diagnosis results not only increase the number of diagnosis items but also improve the diagnosis accuracy of the soundness. This also can output the diagnosis result as A4 size PDF.
To use the extended verification function, separately purchase the "FSA130 ADMAG TI Verification Tool".

Enhanced Verification

Available microSD Card

Have you ever taken the time to backup device parameters, copy parameters to replacement devices, etc.?
Also, have you ever wanted to simply record process information without using an external device?

microSD Card

With ADMAG AXW, you can install microSD card to the converter by selecting option.
Using the microSD card enables easy recording of process information in addition to backup / restore / duplication of parameters, which is useful for improving maintenance work efficiency and analyzing process status.

 

Parameter Backup / Restore / Duplication Function

Parameter Backup/Restore/Duplication Function

ADMAG AXW can be equipped with a microSD card (optional) and can backup / restore / duplicate parameter information using the microSD card or a memory with a built-in LCD.

Function Description
Backup Save parameter information to microSD card or memory with built-in LCD
Restore Download parameter information to the same device (Device A to A)
Duplication Download parameter information to other devices with the same model name and the same specification code (Device A to B)

With these functions, for example, if there is a defect in the parameter settings, you can restore the previous settings.
In addition, since the factory settings are maintained, it is possible to reset to the factory settings.
Furthermore, it is possible to duplicate multiple devices with the same parameters, which contributes to the realization of rapid device replacement.

Dual Frequency Excitation Method

Dual Frequency Excitation Method

By combining the signals obtained by low frequency excitation and high frequency excitation, it is our unique revolutionary excitation method that has succeeded in covering each defect and extracting only the superiority.
It combines the advantages of low frequency excitation zero points stability, high frequency excitation noise resistance and high speed response.

 

Both noise resistance and zero points stability

Both noise resistance and zero point stability

The fluid noise that appears when measuring slurry fluid or low conductivity fluid has "1/f characteristics".
In other words, low frequency components tend to be noisy, while high frequency components tend to be less noisy.
Therefore, high frequency excitation is effective to ensure noise resistance.
However, in conventional high frequency excitation, there was a problem that "zero points become unstable".

In "Dual Frequency Excitation Method", sampling is performed in the area not affected by noise on the high frequency side, and stable zero points components are extracted with a large time constant on the low frequency side.
Therefore, the synthesized signal has a very small effect of noise and stable zero points.

 

"0.1 seconds" fast response

In order to realize the stability of the zero points while reducing the influence of noise, the time constant is generally increased.
But that would hurt responsiveness.
The solution is "Dual Frequency Excitation Method" how to simultaneously meet the effects of noise reduction, zero points stability and response.
In “Dual Frequency Excitation Method”, high-speed response of “0.1 seconds” is possible because the change in flow rate is detected on the high frequency side.

 

Display and output of Flow Noise Intensity

Conventional models have removed fluid noise signals using our proprietary signal processing technology "Dual Frequency Excitation Method". On the other hand, understanding the fluid noise signal is also useful for identifying the cause of occurrence and preventing it.

With ADMAG AXG, the intensity of fluid noise can be displayed and output separately from flow signal output.
As a result, while realizing stable flow rate measurement, it has become possible to grasp at what intensity fluid noise is generated.
This makes it possible to monitor conditions such as air bubble / slurry contamination, lining wear, and liquid replacement (chemical injection, cleaning) that are the causes of fluid noise.

Electrode Adhesion Detection

Electrode Adhesion Detection

Preventing electrode adhesion in advance is one point of stable flow rate measurement.
With ADMAG AXW, the degree of adhesion can be displayed in 4 levels.
In addition, the degree of adhesion in the detector can be grasped while installed in piping, which contributes to the reduction of inspection man-hours.

 

Sensor Empty Check

The electromagnetic flowmeter can not perform accurate measurement if the inside of the detector is empty (non-full).
In ADMAG AXW, by constantly monitoring the condition in the piping, it contributes to the realization of continuous and stable flow measurement.

Mobile Field Device Management (FieldMate)

FieldMate 3.0 is a PC based tool that enables you to see intelligent field devices clearly, know their condition in advance, and act with agility throughout maintenance work flow.
