E C H N OL O G Y D E SC RI PT I O N The core of the proof (or seismic) mass of InnaLabs® pendulous accelerometers is a high purity fused quartz disc structure connected to a rigid outer frame by two thin hinges (Figure 1). - Page 9 This current is output on the Signal Out pin as the acceleration signal. Typically, a precision resistor is used externally to the accelerometer to convert the current output to a voltage. Page 9 of 31 INNALABS PROPRIETARY INFORMATION www.innalabs.com...

Page 17: Electrical Characteristics
With a scale factor of 1.46 mA/V, a 147 Ω (or less) resistor is required at ±28 V in order to meet the full measurement range. The absolute acceleration limit over temperature is dependent on the range of the parameters in the equation above. Page 17 of 31 INNALABS PROPRIETARY INFORMATION www.innalabs.com... -
