Description

The A/127/V is a micro miniature IEPE (voltage output) accelerometer designed for vibration measurement where extremely low sensor mass and minimal mass loading are essential. Manufactured in titanium with an all-welded construction and DJB’s Konic Shear® sensing technology, the low mass of the A/127/V helps minimise influence on lightweight structures during testing.

The A/127/V is adhesive mounted and a detachment tool is provided to shear adhesive joints during removal. Shock removal should be avoided as it may compromise the integrity of the transducer. Abrasive cleaning of the attachment face can reduce base thickness over time, so sparing use of adhesive will support longevity.

Design and construction

The A/127/V is a sub-miniature teardrop IEPE accelerometer manufactured in titanium with an all-welded construction for a robust build. DJB’s unique Konic Shear® sensing element supports stable measurement performance in a compact, low-mass format designed to reduce mass loading effects.

Signal output is via a KP miniature microdot connector, supporting installation in confined test setups where low mass and small geometry are required.
