1 General description
This document describes an inclinometer sub-assembly module, suitable to be built-in in various
industrial applications. Inclinometer is available in 2 axis configuration, for horizontal mounting (X
and Y tilt measurement). The sensor technology used is VTI’s 3D MEMS, with appropriate ASIC
circuitry. Output signals are analogue voltage.

The measuring range is limited by sensitivity, offset and supply voltage rails of the device.
Offset specified as Voffset = Vout(@0°) [V].
+5V supply voltage used in calibration and testing.
See proposed connection of SCL1700 in picture 2.
Offset calibration error specified as Offset_Calib_error = arcsin(Offset_Calib_error_in_g) [ ° ],
Offset_Calib_error_in_g = {Vout(@0°) – 2.5 V} / Vsens [g], Vsens=8.595 V/g.
Offset temperature error specified as Offset_Error_@_temp. = arcsin(Offset_Error_@_temp_in_g) [ ° ],
Offset_Error_@_temp_in_g = {Vout @ temp. – Vout @ room temp.} / Vsens [g], Vsens=8.595 V/g.
Sensitivity target in calibration 8.595 V/g (à 150 mV/°)
Sensitivity specified as Vsens = {Vout(@+10°) - Vout(@+10°)}/(2*sin(10°) g) [V/g].
Sensitivity calibration error specified as Sensitivity_calibr_error = {Vsens - Vsens_nom} / Vsens_nom x 100% [%],
Vsens_nom = nominal sensitivity.
Sensitivity temperature error specified as
Sensitivity_temp_error = {Vsens @ temp – Vsens @ room temp} / Vsens @ room temp} x 100% [%].
From best fit sine-function to output through –10° and +10° (SINE COMPENSATED).
