model 7290E. The phase shift will be almost 0 degrees at 1 Hz. Back to ask the experts

The 7290E is a unique variable capacitance, DC accelerometer designed to measure the low g, low frequency characteristics of flutter phenomena. This device has a frequency response of 0-15 Hz at a range of ±2 g’s and 0-2000 Hz at ±100 g’s at its highest range. E
