Introduction
The complete solution includes:
- DynaLogger, with vibration and temperature sensors and internal memory for data storage.
- Application, for data collection, action and analysis on the shop floor;
- Web Platform, with historic data and diagnostic tools for data analysis.
In addition, a DynaGateway could be added to the solution in order to automate data collection from the DynaLoggers and send the data directly to the Web Platform.
Figure: DynaPredict Solution
The flowchart below shows a basic step-by-step outline of how the solution works:
Accessing the system
Install Mobile App
To configure data loggers, spots and machines, it is necessary to download
the “DynaPredict” app. The app is available on Android (version 5.0Ⓡ or above)
and iOS (version 11 or above) devices and is compatible with smartphones and
tablets.
To install the app, simply search for “dynapredict” on the app store of the
device (Google Play Store/App Store) and complete the download.
It is also possible to down- load the Android version from a computer by
accessing the link:
https://play.google.com/store/apps/details?id=solutions.dynamox.predict
Note: You must be logged in to your Google account and it must be the same
that is regis- tered on the Play Store of your Android device.
Access to the Web Platform
To create the hierarchical sensor and gateway installation struc-ture, as well
as access the entire history of vibration and temperature measurements
collected by the DynaLoggers, users have a complete Web Platform at their
disposal.
Simply access the link https://dyp.dynamox.solutions and log in to the
system with your access credentials.
Now you’ll have access to the Web Platform and can consult the data of all the
registered DynaLoggers.
To learn more about the operation of the Platform and its features, please
read the “DynaPredict Web Platform” manual.
Structuring the Asset Tree
Before placing sensors in the field, it is recommended to ensure that the asset
tree (hierarchical structure) is properly created, with the monitoring points
already standardized waiting for the sensor that will be associated to it. To
learn all the details and understand how to perform the asset tree structuring
process, please read the article Asset Tree Manegement.
This facilitates the work in the field and ensures that the points are
registered in the correct structure.
The asset tree structure should be defined by the customer and, preferably,
follow the standard already used by the company in ERP software (SAP, for
example).
After creating the asset tree via the Web Platform, the user should ideally
also register the monitoring point (called the spot) in the tree structure,
before going into the field to perform the physical installation of the
sensors. The image in the next page shows an example of an asset tree.
With these procedures completed, the user can finally go into the field to
perform the physical installation of the sensors on the machines and
components registered in the asset tree.
After finishing these procedures, the user can finally go into the field and
perform the physical installation of the sensors on the machines and
components registered in the asset tree.
More details regarding this process are present in the following articles of
this section.
Positioning the DynaLoggers
Before carrying out the physical installation of the sensors on the machines,
here are a few recommendations:
The first step, in the case of explosive atmospheres, is to consult possible
restrictions on the product datasheet.
Regarding to vibration and temperature parameter measurements, these should be
taken on rigid parts of the machinery. Installation on fins and in fuselage
regions should be avoided, as these may present resonances, attenuate the
signal, and dissipate heat. In addition, the device should preferably be
positioned on a non-rotating part of the machine.
Since the DynaLoggers take readings on three orthogonal axes, they can be
installed in any angular direction. However, it is recommended that one of the
axes (X,Y,Z) be aligned with the machine shaft.
Figure: Axes orientation
Left: DynaLogger TcA+. Right: DynaLoggers HF and HF+
The images above show the orientation of the DynaLogger axes. This can also be seen on the label attached to the devices. The correct positioning of the device should take into account the axis and orientation of the machine.
- The DynaLogger must be installed in a rigid part of the ma- chine, avoiding regions that may present localized resonance;
- Preferably, the DynaLogger should be centered in relation to critical components, such as bearings;
- It is recommended to keep the DynaLogger at a fixed point, i.e., to define a definite installation for each device in order to obtain repeatability in measurements and a history of quality data;
- It is recommended to verify that the surface temperature of the monitoring point is within the recommended limits (-10ºC to 84ºC) for the use of DynaLoggers. Using the DynaLoggers at temperatures outside the specified range will void the product warranty;
Regarding the actual installation locations, we have created a suggestion guide for the most common machine types. This guide can be found on our Support page (https://support.dynamox.net), in the section “Applications and good monitoring practices”.
Mounting
The mounting method is one of the most critical factors for measuring vibration. A rigid attachment is essential for avoiding false readings and data.
Depending on the type of machine and position, different mounting methods could be used. To get the best results from the DynaPredict solution, screw mounting is recommended. To do this, the installation surface must be prepared first, as described below.
Screw Mounting
Before choosing this mounting method, check that the installation point on
the equipment is thick enough for drilling.
If so, follow the step-by-step procedure below Drilling the Machine Drill a
threaded hole with an M6x1 threaded tap (supplied in kits with 21 DynaLoggers)
at the point of measurement, at least 15mm deep.
Cleaning
Using a wire brush or fine sandpaper, clean any solid particles and scale on
the surface of the measurement point.
After surface preparation, the DynaLogger attachment process should begin.
DynaLogger mounting
Position the DynaLogger at the measurement point so that the base of the
device is completely supported by the installation
surface. Once this is done, tighten the screw and spring washer* supplied with
the product, applying a tightening torque of 11Nm.
- Use of spring washer is critical to achieving reliable results.
Adhesive Mounting
Glue mounting can be advantageous in some cases:
– Mounting on curved surfaces, that is, where the DynaLogger base will not be
fully supported on the surface of the measurement spot;
– Mouting in components that do not allow drilling of at least 15mm;
– Installations on in which the DynaLogger’s Z axis is not posi-tioned
vertically in relation to the ground;
– Installations of DynaLogger TcAs and TcAg, since these models only allow
glue mounting.
For these cases, in addition to the traditional surface prepara-tion described
above, chemical cleaning must also be carried out on site.
Chemical cleaning
Using an appropriate solvent, remove any oil or grease resi- due that may be
at the installation site.
After surface preparation, the glue preparation process should begin.
Preparation of the Adhesive
The most suitable adhesives for this type of fixation, according to tests
conducted by Dynamox, are the Scotch Weld DP-8810 or DP-8405 structural
adhesives from 3M. Follow the preparation instructions described in the manual
of the adhesive itself.
Dynalogger Mounting
Apply the glue so that it covers the DynaLogger’s entire bottom surface,
completely filling the center hole. Apply the glue from the middle to the
edges.
Press the DynaLogger on the selected location, orienting the axes (drawn on
the product label) in the most appropriate way.
Wait for the curing time indicated in the manual of the glue manufacturer
itself, in order to guarantee the good fixation of the DynaLogger.
Registering a DynaLogger – Getting Started
After attaching the DynaLogger in the desired location, you must associate its
serial number with the spot created earlier in the asset tree.
Each DynaLogger has a serial number that identifies it:
Figure: DynaLogger HF+ – Serial number on the top of the device
The process of registering a DynaLogger to a spot is done via Mobile
Application. Therefore, make sure you have downloaded the App on your
smartphone before going to the field to install the sensor.
By logging into the App with your access credentials, all sectors, machines,
and their divisions will be visible, as previously created in the asset tree
via the Web Platform.
To finally associate each DynaLogger to its respective monitor- ing site,
simply follow the procedure detailed in the article Associate a DynaLogger to
the spot.
At the end of this procedure, the DynaLogger will be working and collecting
vibration and temperature data as configured.
