Max non-conformance (% fs) : 0.02
Sensor gauge factor : 15.998 Volts/Sin(90)
Calculation of tilt value (arc degree) :
SinA = Observed output / gauge factor
A = Sin -1 (observed output / gauge factor)
Wiring colour code :
Wire colour Signal
Red +12 V (supply )
Black - 12 V (supply )
Green 0 V (supply )
Blue Output 'A' axis
Brown N/A
White Output common
Note : * Calculated output Voltage (V

) worked out based on nominal gauge factor of 16.000 V/g
(i.e. 16V X Sin A).
