Description
Overview
The Bruel & Kjaer 2525 is a precision measuring amplifier designed for product and prototype testing, vibration analysis, and accelerometer measurements. It features low-noise amplification with both charge and CCLD inputs, making it suitable for a wide range of transducers. The instrument includes automatic gain adjustment, level monitoring with alarm output, and the ability to store and recall up to eight amplifier setups for rapid and accurate test configuration.
Key Features
- Charge and CCLD input compatibility with floating or grounded configurations
- IEEE-488 and serial interfaces for remote control and automation
- Selectable low- and high-pass filters with provision for user-defined and external filters
- Signal integration for converting acceleration to velocity and displacement
- Wide dynamic range of 100 dB with -20 dB to +60 dB input gain adjustment
- Multiple measurement modes: acceleration, velocity, displacement, and force
- RMS, peak, and peak-to-peak detection with metric or imperial unit readout
- Autorange function for automatic gain adjustment
- Level monitoring with alarm output and signal overload indication
- Transducer sensitivity adjustment and mounted resonance measurement for accelerometer verification
- Exponential or linear RMS averaging with selectable averaging time
Applications
- Product performance testing and validation
- Prototype vibration analysis and characterization
- Accelerometer mounting verification and resonance testing
- Automated measurement systems and remote control operations
