Piezoelectric Triaxial Accelerometer - AT/04
The AT/04 is a lightweight triaxial piezoelectric charge output accelerometer designed for reliable vibration measurement in demanding test environments. Featuring three Konic Shear® sensing elements in a fully welded titanium block and an industry-standard ¼-28 UNF 4-pin connector, it supports simplified single-cable installation with low-noise 4-core cabling to help reduce triboelectric noise.
Description
The AT/04 is a lightweight triaxial piezoelectric charge output accelerometer designed for general-purpose vibration measurement in demanding test environments. It comprises three Konic Shear® charge output sensing elements mounted orthogonally within a fully welded titanium block, supporting rugged and repeatable triaxial measurement with minimised cross-axis effects.
Key specifications
- Sensitivity: 5 pC/g nominal
- Weight: 13–16.6 g (variant dependent)
- Maximum temperature: -50°C to 200°C
Model variations
- AT/04
- AT/04/TB
Design and construction
The AT/04 is a general-purpose triaxial charge output vibration transducer with three charge output Konic Shear® piezoelectric sensing elements mounted orthogonally within a fully welded titanium block. The AT/04 is one of only three single-connector piezoelectric charge output triaxial accelerometers in the world, all produced by DJB Instruments. This is enabled by DJB’s low-noise 4-core cable assemblies, designed to help reduce triboelectric noise effects.
Using an industry-standard ¼-28 UNF 4-pin connector, the AT/04 is available with standard or ruggedised cable options and three BNC-labelled breakout leads. The AT/04 includes an integrated ceramic isolating base to provide complete ground isolation, making it well suited to automotive and aerospace test environments.
