Measurement applications
OBSESSIO X2 is intended for crack and structural displacement monitoring with an LVDT or potentiometric sensor. The choice should take into account the measurement range and the project conditions.
When to choose OBSESSIO X2?
Consider OBSESSIO X2 when you need an LVDT interface. With the reference LVDT sensor, its datasheet specifies a ± 5 mm range, ± 0.01 µm resolution and ≤ 10 µm accuracy (module + probe). See the datasheet for the measurement conditions.

Preparing your installation
To prepare your request, tell us the phenomenon to measure, the expected measurement range, the number of monitoring points and the installation conditions. Also specify your connectivity and data access needs.
Frequently asked questions
Can the sensors be configured locally?
Yes. OBSESSIO X1, OBSESSIO X2 and DISTANCIO are configured and read locally from a smartphone, tablet or PC over Bluetooth/NFC; HORIZIO is configured over Bluetooth.
Which transmission options are available?
Depending on the model: Sigfox, LoRaWAN and LoRa P2P. The PACK FISSURE AUTONOME works with Sigfox or LoRaWAN. The datasheets of OBSESSIO X1, X2, HORIZIO and DISTANCIO also mention M2M radio protocols (Long Distance, Low Power). Tell us the connectivity constraints of your site.
