7. Gateway
The Gateways automatically collect data from the DynaLoggers within their Bluetooth range and send it directly to the Web Platform, and allow the scheduling of spectral analysis.
It is important to note that a Gateway does not eliminate the need for the application, since the app alone enables the initial configuration of the DynaLoggers.
However, it is an important ally to optimize the data collection process.
To learn more about how the Gateway works and its features, read the Gateway Manual.
6. Registering a DynaLogger
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:
DynaLogger HF – Serial Number
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.
Then, all you have to do is associate DynaLogger with its respective monitoring spot.
At the end of this procedure, the DynaLogger will be working and collecting vibration and temperature data as configured.
5. 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 attachment
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 the spring washer is critical to achieving reliable results.
Adhesive Mounting
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 Attachment
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.
DynaLogger installation with glue fixation
Press the DynaLogger on the measuring point, 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.
4. Positioning
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.
Left: DynaLogger TcA+. Right: DynaLogger 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 image below shows a DynaLogger positioned on an electric motor.
X=Axial; Y=Horizontal; Z=Radial
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 machine, 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.
3. 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 below 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.
2. Acessing 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 download 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 registered on the Play Store of your Android device.
Accessing the Web Platform
To create the hierarchical sensor and gateway installation structure, 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” manual.
