Note 1. Note 2. Note 3. Note 4. Note 5. Note 6. The measuring range is limited by sensitivity, offset and supply voltage rails of the device. Offset specified as Voffset = Vout(@0 ) [V]. +15 V supply voltage used in calibration and testing. 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=11.46 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=11.46 V/g. Sensitivity target in calibration Vsens _nom 11.46 V/g (--> 200 mV/) Sensitivity specified as Vsens = {Vout(@+10 ) - Vout(@+10 )}/(2*sin(10 ) g) [V/g]. Note 7. Note 8. Note 9. 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 . Rev. 10 Sept 2004 VTI Technologies reserves the right to modify this specification without prior to notice. SCL1700 Series MEASURING DIRECTIONS Connector + Sensor y-axis OUTPUT SIGNAL - Earth's gravity x-axis Notes: * It is important that the part is mounted horizontally. Measuring axes are X and Y according to above figure. * Above figures provide information on how the output of the inclinometer behaves in different circumstances. Please also note that you can rotate the part around the measuring plane for optimum mounting location. + ELECTRICAL CONNECTION Name Vcc NC GND OutX OutY NC Fuction Power supply, 7 - 28 V Internally not connected Ground Analoque X-direction output Analoque Y-direction output Internally not connected Connector pin 1 2 3 4 5 6 Connector: Molex, Pcoflex PF-50 MECHANICAL SPECIFICATIONS * * * * * * * PCB Material: PCB thickness: Size: Height: Mounting holes: Weight: Connector: FR4 1.6 mm 45 mm x 45 mm max 10 mm O 3.5 mm < 10 g Molex, Picoflex PF-50, 1.27 mm pitch, mates with Molex 90327 45.00 mm 38.00 mm 45.00 mm 38.00 mm Pin# 1 Pin# 6 Mechanical dimensions in mm.
