Output %
Tests were conducted by exciting the outer electrodes of the
sensor in a single axis mode using the Fredericks Universal
signal conditioner. Output curve and linearity specifications are
shown above. Information on electrolytic tilt sensor signal
conditioning is available on the Fredericks web site at
www.frederickscom.com.

Caution!-Ensure that all test and operating circuits are
entirely free of direct current. Direct current will
cause level damage and/or instability.
Note! – The housing (center pin) is the active output
signal. The unit must be electrically isolated.
