We discuss each of these three here. Supports The Tilt90 node needs to be mounted on a support. Depending on the application, it needs to be installed with a certain inclination to achieve curved surfaces and on others applications it can be just installed aligned to the surface. -
Page 13: Powering Up The Device
Powering up the Device Loadsensing devices are shipped closed and without batteries. To power up the device: Open the device using a 2.5 mm Allen wrench. 2. Insert C-type batteries in the battery holders, checking they match the polarity indicated. You can connect one or more batteries; the more you use, the longer the device will operate in the field. -
Page 14: Loadsensing Device Configuration
General warnings Follow these precautions to avoid a battery explosion or leakage of flammable liquid or ● gas: ○ Use the correct battery type. Dispose of the batteries according to instructions. Do not dispose of the batteries by throwing them into a fire or a hot oven, or mechanically crush or cut them. - Page 15 Please take note of the following credentials in the Gateway Information Sheet. These will be necessary to perform the radio coverage test: Gateway Information Sheet Mobile app field Default network ID Network ID Default network key Password Default network access password Server password The process for configuring the TIL90 node is the same as the other nodes and it is detailed on the WorldsensingApp user guide.
- Page 16 This node integrates one sensor, and it is not necessary to configure the sensor’s settings on the WorldsensingApp. Once the radio configuration is finished the app will show the option of taking a sample. Taking a sample will show the parameters measured and allow you to check the consistency of the readings.

Page 17: Safely Closing The Device
The app will show tiltmeter readings: the 3-axis inclination measurement with respect to gravity’s direction, its standard deviation (expressed in Gravity) and also the internal temperature of the node. 3-axis Inclination measured by the tiltmeter is calculated as the average of a certain amount of acceleration samples in a period. -

Note that box screws shouldn’t be torqued more than 2 Nm. If you exceed the torque, the Helicoil insert may be damaged. We do not recommend using electric drills or electric screwdrivers. 10. Understanding data In this chapter we will explain how the TIL90 can be installed, what it measures and which parameters can be read. -
Page 19: Calibration
Figure 8: Values of 3 axes on di erent angle installations. 10.1.1 Calibration The tiltmeter sensor is assembled, calibrated and tested under stringent quality control standards. The coe cients for the linear equation are determined with 4 inclination steps (0, 90, 180, 270 degrees) between the XZ and YZ planes. - Page 20 Regarding the recalibration of the wireless tiltmeter, Worldsensing recommends recalibrations only for the following situations: When a tiltmeter certificate is required according to the quality program of the ● company/project. In this case, the certificate may be obtained locally. If a laboratory with a proper rotary frame is locally accessible, the wireless tiltmeter may be placed on the calibration frame to take measurements at di erent inclination steps.

12. Errors implemented When an error is returned a new timestamp is registered on the reading error CSV file on the Gateway, the reading file will show blank readings corresponding to that timestamp. There are several errors that can be returned on the CSV file, related to the tiltmeter sensor or the laser distance meter. -

node should never be submerged in water. WATER DAMAGE TO INTERNAL COMPONENTS VOIDS THE WARRANTY. In case of doubt regarding the reliability of the readings, first inspect the wireless node mounting and the structure where it is attached. Any compromise to or mechanical deformation of the mounting hardware can cause unstable readings. - Page 25 Sampling rate SF9@14dBm SF8@20dBm 30 sec 3.1 months 5 months 1 min 6 months 8.7 months 5 min 2.1 years 3 years 30 min 6.8 years 8 years 8.7 years 9.5 years 11.3 years 11,5 years 11,6 years 11.7 years 12 h Table 1: Battery lifespan in years assuming intermediate environmental Radio conditions for European and FCC radios...

16. FAQs Do I need to apply temperature correction to the wireless tiltmeter? The wireless sensor temperature dependency is up to +/-0.002°C for the TIL90-X and +/-0.005°C for the TIL90-I . To reduce thermal e ects, we recommend installing the device indoors where possible in order to avoid sun exposure. - Page 29 important point to be considered. This makes the specs from TIL90-I lower than the TIL90-X. I am not able to upgrade the node firmware version, when trying to advance an unexpected error appears on the App screen. How can I solve this problem? TIL90 can only be powered by using batteries, thus in case of batteries have been depleted and the node is trying to be upgraded, you will see the following sequence:...
