Metrozet TSA-100S Accelerometer Response

TSA-100S Sensitivities

Nominal sensitivity in V/m/s**2 is

G in V/m/(s*s) = [Full scale voltage / Clip level] / [9.80665 m/(g * s**2)].

Voltages and Output Types

To translate the Sensor Output Voltage Level and Output Type to Full Scale Voltage shown below, know that the Sensor Output Voltage Level is the maximum voltage for the acceleration range or clip level from a single output.

If the sensor has, for example, a single-ended (positive) output and an Output Voltage Level of 2.5V, a positive maximum acceleration would generate +2.5V. Likewise, the maximum negative acceleration would generate -2.5V. Therefore,

If the sensor has differential (a positive and negative) output and an Output Voltage Level of 2.5V, a positive maximum acceleration would generate +2.5V from the positive output and -2.5V from the negative output for a sum of +5V. Likewise, the maximum negative acceleration would generate -5V from the sum of the positive and negative outputs. Therefore,

TSA-SMA Accelerometer Response

Only the number of poles and zeros, the A0 normalization factor and sensitivity were available for the TSA-SMA accelerometer. The pole values were adopted from the TSA-100S, the zero was dropped and the complex conjugate pole pair for the feedback electronics was adjusted to fit the available information. This is the best estimate to fit the information available, but small differences above 100 Hz can't be ruled out.
