Description
Overview
Bruel & Kjaer's Type 4321 is a triaxial piezoelectric accelerometer featuring a titanium housing and three autonomous outputs. It is ideal for simultaneous measurements in three mutually perpendicular directions, with each of the three individual transducers adjusted autonomously. The accelerometer connects via three receptacles (10–32 UNF-2A) and can be mounted using an M4 screw or similar threaded steel stud. It can also function as a charge source.
Key Features
- Triaxial design with three autonomous outputs for independent 3-axis measurement
- DeltaShear piezoelectric design with elevated sensitivity-to-mass ratio
- High isolation from temperature transients and base strain with high resonance frequency
- Titanium housing for durability
- Three independent masses and piezoelectric elements arranged in triangular configuration
- Sensitivity expressed in charge per unit acceleration (pC/g)
- PZ 23 lead zirconate titanate (PZT) piezoelectric element
Applications
- Three-axis vibration monitoring
- Structural health monitoring
- Shock and impact measurement
- Laboratory and field testing
