The Columbia Model SA-100MR offers the superior performance of force balance technology with the flexibility of multiple operating ranges for DC and low frequency measurements. The accelerometer is self-contained and provides a high level, low impedance output. No signal conditioning is required in most applications.
The full range for Model SA-100MR is specified when the accelerometer is ordered. The range may then be adjusted from 0.05 to 1 times the full range by means of an external resistor. The selected range always corresponds to an output of ±7.5 volts. The noise floor remains constant and does not increase as the scale factor is increased, thereby achieving the optimum signal-to-noise ratio for any range selected.
