OBSESSIO X1, X2 or PACK FISSURE: which solution should you choose?
These three solutions address crack or displacement monitoring needs. Compare the measuring principle and the stated specifications, then discuss the constraints of your project with ADVARNA.

The values above are the stated specifications of each solution (datasheets for OBSESSIO X1 and X2). Measurement conditions and configurations are not necessarily the same: accuracy alone is not enough to choose a product.
Questions to consider before choosing
What displacement do you need to measure? What stroke is required? What type of sensor will you use? What accuracy are you looking for and what connectivity is available on site? These points let you compare the solutions in the context of your application.
You use a potentiometric measurement
See OBSESSIO X1 and check the specifications of the associated sensor.
OBSESSIO X1You use an LVDT measurement
See OBSESSIO X2 and review the specifications of the intended configuration.
OBSESSIO X2You are looking for a crack monitoring pack
Look at the PACK FISSURE AUTONOME, the stroke offered and the one-year subscription included.
