Horizontal Inclinometer Probe The data processing is usually made using a dedicated software i e FIELD SISGEO INCLI2 see the reference manual for further details Herewith below are clarified the basic notions for data processing SISGEO inclinometer probes have a constant k of 20000 Different k shall be required at order placing The values digits displayed from SISGEO dataloggers are digits sina x k Example Ch A 698 digits a arcsin 698 20000 2 To calculate the casing inclination at each quote proceed with the following formula D P x sind where D casing displacements at the generic quote P measurement step sina casing inclination angle at the generic quote The inclination value for each measuring step is A1 A3 2 Example G At i quote we have the following values A1 480 A3 506 P 500mm The inclination at the i quote is 12 325mm To calculate the global displacement D of the casing proceed with the following formula Horizontal inclinometer probe EN 00 12 Page 8 of 13 SISGEO S r l Horizontal Inclinometer Probe The global displacement calculation must be done considering that one of the end of the casing is not subject to movements or considering the absolute displacements of the casing taken for example by means of topographic measurements Hints on checksum The checksum is the algebraic half sum of the measurements obtained on the m
