Positioning a sensor

Mon, 01 Jan 0001 00:00:00 +0000

To detect abnormalities in machine components, install Treon sensors in locations where temperature and vibration can be measured effectively.

Best Practices for Sensor Placement

Mount directly on the housing of the target component for accurate readings.
Minimize the vibration transmission path — the distance between the vibration source and the sensor.
Avoid mounting on flexible or resonant surfaces, such as sheet metal covers, which can oscillate and distort measurements.

Vibration attenuates up to 75–90 cm (30–36") from the source.

Attributes of the vibration transmission path that can reduce the transmission path length include:

The number of mounting surfaces, which can cause signal reflection.
Materials like rubber or plastic can absorb vibration and reduce accuracy.

⚠️ Treon Industrial Node C sensors measure vibration on three axes (X, Y, Z). These axes are marked on the sensor body. You do not need to align a specific axis with the machine’s vibration direction.

Examples of Sensor Placement

Electric Motor

Two sensors on the motor

Place sensors close to the primary vibration source. For gearboxes, consider how vibration transmits through connected components. For bearings, position the sensor near the load zone (the area under the most stress).

ℹ️ The shortest distance to the vibration source is not always the best location. Consider how vibration travels through the machine structure.

Mounting a sensor

Mon, 01 Jan 0001 00:00:00 +0000

The temperature and vibration sensors in the Treon Industrial Node C are located at the base of the device. Any part of the base can serve as a contact point, but for accurate readings, the contact area should be at least 30 x 25 mm. For best results, center this contact area over the mounting location. The circular aluminum element at the center of the base transfers heat directly from the asset’s surface to the internal temperature sensor.

Identify the optimal location and orientation on the asset for effective monitoring, then mount the sensor at that spot. To install the sensor, you will need to purchase an industrial adhesive. We recommend cyanoacrylate-based adhesives such as Loctite 454, Loctite 3090, Loctite 4070, or a similar product.

For flat and smooth surfaces, a thin layer of adhesive like Loctite 454 is sufficient.
For curved or uneven surfaces, apply a slightly thicker layer of adhesive such as Loctite 3090 or Loctite 4070 to ensure a secure bond.

If you are uncertain of where to mount your Treon Industrial Node C sensors, see our article on Positioning a sensor.

⚠️ Warning: When installing sensors, ensure you review and comply with all relevant safety regulations. You are solely responsible for the safe installation of the sensor on any equipment or machine component. Mounting the sensor requires the use of an industrial adhesive. Always follow the safety and handling guidelines provided by the adhesive manufacturer.

For more information about the recommended adhesive, see the technical information:

To mount a sensor

To mount a Treon Industrial Node C sensor, follow these steps:

Surface preparation:
Thoroughly remove all oil, grease, and debris from the surface where the sensor will be installed.
Sensor glueing:
If the surface that you’re mounting the sensor to is flat and relatively smooth, apply a thin layer of adhesive such as Loctite 454 to the bottom of the sensor, maximizing the area that will be in contact with the asset.

If the surface is rounded or somewhat uneven, apply a slightly more liberal layer of adhesive such as Loctite 3090 or Loctite 4070 to the bottom of the sensor. The layer of adhesive can bridge distances of up to 5 mm between the surface and the sensor if necessary.
Hold the sensor:
Hold the sensor to the mounting location on the machine part for 30 seconds, pressing firmly. If you’re mounting the sensor on a curved surface, put a small amount of additional adhesive on each side for better contact between the sensor and the surface. Based on the surface and the adhesive used, your results should look similar to the following.
Success:
Your Treon Industrial Node C sensor has been successfully glued to an asset and is ready for use!

Commission Treon Industrial Node C

Mon, 01 Jan 0001 00:00:00 +0000

The Treon Industrial Node C is a wireless battery-operated sensor device for collecting condition monitoring data of industrial equipment.

When the device is powered on and provisioned, it starts automatically to measure and transmit data.

The Treon Industrial Node C uses wireless Bluetooth connectivity to transmit sensor values to a gateway. The data is sent via the gateway to the Treon Connect cloud backend, for analysis or delivery to other systems.

Commissioning a sensor attaches it to an asset in your Treon Connect environment.

For commissioning a sensor you need an NFC-capable smart phone and the Treon Connect app, and you need to be in close proximity to the sensors you want to commission.

1. Turn on NFC on your phone

To enable NFC on an Android device, go to Settings > Connected devices > Connection preferences > NFC, then toggle the switch to On. Once activated, the device can exchange data with other NFC-enabled devices or tags when they are nearby.

2. Start the Treon Connect app

To start the Treon Connect app, simply tap its icon from your Android device’s home screen or app drawer.

If your Treon Connect app is not yet connected to your Treon Connect instance, please log in with your user credentials.

3. Choose the Asset

From the asset list in the Treon Connect app, tap the specific asset you want to attach the sensor to in order to proceed with commissioning the sensor.

4. Attach the sensor to start NFC pairing

Bring the smartphone NFC field to the proximity of the sensor.

Press the Attach Device button in the Treon Connect app to automatically initiate NFC pairing with the sensor.

Now hold the Treon Industrial Node C close to your phone’s NFC sensor until the pairing process begins automatically.

5: Wait for successful NFC pairing

The Treon Connect app displays the progress of the sensor commisioning on the screen.

Please keep the phone and the Treon Industrial Node C sensor steady during the pairing process. In case the NFC pairing fails, please start the process new by pressing the Try Again button.

6. Specify Device Properties

After the sensor has been paired and commissioned successfully, you are asked to fill in the details of the sensor deployment.

Name: Name the sensor according to it’s deployment position. Choose a name that clearly identifies the specific sensor.

Examples for easily identifiable namings are:

“Conveyor belt B2, position 3, left side”
“Fork lift 3, motor top side”

Installation Position: Describe the positon of the sensor on the asset.

Device Class: Select a Device Class for the asset from the pre-defined list. Assinging the Device class will automatically enable class-based event-rules for alerts and warnings.

Take Picture: In order to identify the position of the sensor on the asset, you can take a photo. After pressing the button Take Picture, take a picture of the sensor with your phone’s camera.

After you have entered all necessariy data, press the Attach button to complete commissioning the sensor device.

7. Completion

Your sensor device has now been commissioned and is attached to an asset in your Treon Connect instance.

Please note that the sensor will not begin transmitting data immediately after commissioning. Commissioning initiates the sensor’s internal clock cycle, during which it will send measurements at regular intervals. It may take several measurement cycles before the first data is successfully transmitted to the cloud. Once transmission begins, the sensor will continue sending data consistently.

Alternative: Manually attaching a sensor

In case there is an issue with the commissioning process, or your phone does not have NFC capability, you can manually attach a sensor to an Asset.

⚠️ Please note that you can only manually attach a pre-commissioned sensor which already exists in your Treon Connect environment.

Follow steps 1 to 3 as above.

4b. Select manual pairing

Alternatively, you can attach a sensor to an Asset manually. This is only possible if a sensor has previously been commissioned to an Asset linked to your Treon Connect instance.

To start the process, press the Enter Manually button during the NFC pairing process.

5b. Select the sensor

In the menu, select the Treon Node C sensor you want to attach to the Asset from the list of available sensors.

If the sensor is not shown in the list, it likely has not been commissioned to an Asset in your Treon Connect instance yet. Please follow the NFC pairing process to commission the sensor.

Next: Follow steps 6 to 7 as above.

Troubleshooting

Error: "Oops! Something went wrong!" in the login view.

This error occurrs when the phone has no network connection, or very bad network connection. Please make sure your phone has network connection via SIM card or Wi-Fi to continue.

Error: "There are no assets."

No Assets have been created in Treon Connect. Commissioning requires an asset to which the device is commissioned to. Resolve by creating Assets before commissioning the sensors.

Error: Sensor commissioning failed due to NFC disactivation

NFC is switched off on the phone while commissioning a sensor. The Treon Connect app checks that NFC is turned on before starting the commissioning process but not while the process is ongoing. If NFC is turned off during commissioning, the commissioning process will fail. To resolve, please turn on NFC and start the commissioning process of the sensor again. )

Error "Device commissioning failed" during NFC pairing

If the phone with its NFC sensor is moved during the pairing process, it might fail. To resolve, start the commissioning process again and keep the phone steady until the pairing has successfully been finished.

If pairing fails multiple time even if the phone is held completely steady, please contact Treon Support.

Error: Treon Node C sleep cycle

After failing the commissioning, the Treon Node C does a sleep cycle. If the timing of the next attempt is unfortunate (~3-5s after the previous one), the new attempt will fail as well. This can result in a loop where the commissioning never gets the change to start. To resolve this issue, please wait for 10s before starting the commissioning process again.

Error: "Permission Denied. You cannot commision this device."

If the Treon Node C has been commissioned already, and the user does not have access rights to the device in Treon Connect, it is not possible to continue with this sensor. Please contact a user with higher or admin access rights in your organization.
