The Dytran 3168D2 is a new single-axis IEPE quartz accelerometer featuring a through-hole design for 360° cable orientation. Said to be ideal for health and usage monitoring systems (HUMS) and flight test applications, model 3168D2 incorporates mechanical and electrical filters that effectively eliminate ultra high-frequency energy that can cause signal saturation (common in high-speed gearbox applications). The filters also act as a barrier to 'zero shift' phenomena in the data by protecting the sensing element from high-amplitude, high-frequency mechanical impacts. In addition, the filters suppress the natural frequency of the sensor to ensure correct 'in-band' vibration measurements during all test applications.
