Measuring Amplifier -
Type 2525
Measuring Amplifier Type 2525 is a low-noise amplifier featuring both Charge and DeltaTron® inputs, an extended menu-based user-interface for local control and the option of remote, automated control from one of its two interfaces.
The measuring amplifier is well-suited to both product and prototype testing and includes automatic gain adjustment, level monitoring with alarm output and signal overload indication. In addition, the amplifier includes a mounted resonance measuring function for ensuring the best mounting of accelerometers.
An integrator can convert acceleration signals to velocity and displacement and the gain adjustment features ensure rapid and accurate set-up and ease of interpretation.
Up to eight amplifier setups can be stored and recalled, providing, with the interfaces, a platform for fully automatic operation.
In addition to the built-in filters, a 15-pin auxiliary connector is provided for external filter attachment. Additional internal filters can be added upon request.
