In-Depth Overview
The SPEKTRA SE-21 High-Frequency Electrodynamic Exciter is a premium, professional-grade vibration testing solution engineered for precise sensor calibration and advanced multi-axis vibration analysis. Part of the acclaimed SE-2X series from SPEKTRA Dresden, the SE-21 features a uniquely designed cube-shaped ceramic armature enabling excitation along multiple axes to simulate complex vibration environments. This multi-axis capability makes it ideal for industries requiring rigorous vibration and acoustic measurement such as automotive NVH (Noise, Vibration, Harshness) testing, aerospace sensor characterization, manufacturing quality control, and building acoustics validation.
The exciter incorporates a state-of-the-art spring-guided drive system that delivers exceptionally low transverse motion—less than 5% of the main axis movement—ensuring superior measurement accuracy. This aligns the SE-21 with internationally recognized calibration standards, including ISO 16063-11 and ISO 16063-21, guaranteeing reliable and repeatable test results essential for research and industrial applications.
Extending its operational frequency range up to 50 kHz (with optional internal reference sensor), the SE-21 is optimized for high-frequency sensor characterization, particularly suited to MEMS accelerometers and other sensitive devices. It supports demanding environmental conditions with its available temperature variants: the standard model operates between -20°C and +80°C, while the SE-21T variant expands this range from -40°C to +120°C, accommodating harsh testing environments.
Key features include
- Multi-axis, high-frequency electrodynamic excitation
- Unique cube-shaped ceramic armature
- Low transverse motion (<5%) for precise measurements
- Frequency range up to 50 kHz with optional reference sensor
- Compliance with ISO 16063-11 and ISO 16063-21 standards
- Industrial-grade durability and temperature variants
The SE-21 is the preferred choice for engineers, researchers, consultants, and quality control professionals engaged in vibration testing, acoustic analysis, and sensor calibration. Applications span from automotive noise and vibration assessments to aerospace sensor development, environmental monitoring, and building acoustics engineering.
