Presentation
A601-2 is a tiltmeter for geophysical applications requiring high resolution and highest repeatability. A601-2 tiltmeter includes two high-resolution electrolytic sensing elements mounted perpendicularly, enabling detection of minute movements on the X and Y axes (resolution < 25 to 50 nrad depending on measurement range).
4 measurement ranges are available: ±0.0115°, ±0.0235°, ±0.115°, ±0.235°. Output signal is ±8 VDC (unipolar) or ±16 VDC (differential). 2 low-pass filter gain and time constant values are selectable by switch.
