Triaxial accelerometer 8840

crystalpiezoelectricIEPE

Product summary
Type 8840 are quartz shear IEPE accelerometers designed to measure lateral rotational acceleration. The sensor element is arranged to capture the acceleration magnitude of oscillations induced laterally on its mounting base.

Main features

• Shear quartz piezoelectric sensing principle
• Measures lateral oscillations and lateral rotational acceleration
• Hermetic, ground-isolated construction
• Lightweight titanium housing with through-hole mounting
• High immunity to base strain, thermal transients and transverse accelerations
• Wide frequency response

Description
Type 8840 complements shear-mode sensors by responding to a distinct form of induced oscillation. Kistler shear technology yields accurate measurement of lateral rotational acceleration while minimizing sensitivity to base strain and environmental transients. The unit combines wide frequency response with a hermetic, ground-isolated, lightweight titanium construction suited for industrial test and measurement applications.
