The DC to 1000 Hz bandwidth and low noise of these sensors are ideal for many test and measurement applications. The TA Series features a buffered, single-ended output voltage that is measured differentially with respect to a 2.5 V reference. The sensors require a +5 VDC supply voltage. The sensing element of the TA Series consists of a micro-machined silicon mass suspended by multiple beams from a silicon frame. Each hermetically sealed element is signal conditioned, precisely aligned in a mounting block, and potted with an ▼ industrial strength cable. Every unit is thoroughly tested by Crossbow before it leaves the factory. Each sensor is shipped with a calibration sheet stating the zero acceleration output and sensitivity. Additional calibration information, such as a frequency sweep, or temperature drift can also be included. The module may be securely attached using screws or an adhesive. The output requires no signal conditioning and is easy to interface to standard data acquisition systems.

Sensitivity is ratiometric to supply in the range of 5 V ± 0.5 V. Non-linearity is the deviation from a best fit straight line at full scale. Transverse sensitivity is error measured in the primary axis output created by forces induced in the orthogonal axis. Transverse sensitivity error is primarily due to the effects of misalignment. Zero g drift is specified as the typical change in 0 g level from its initial value at +25°C to its worst case value at Tmin or Tmax. Self Test: To enable self-test, ground self-test pin.
