USES: ❍ Manual and automated measurements of vibration levels ❍ General R & D vibration measurements ❍ Test cell monitoring ❍ Production quality control FEATURES: ❍ IEEE–488 and serial interfaces ❍ Charge and DeltaTron inputs ❍ Signal integration for displacement and velocity ❍ Selectable low- and high-pass filters ❍ Possibility for user-defined filters ❍ Connector for external filters ❍ RMS, +peak, –peak, peak-to-peak meter function with read-out in metric or imperial units ❍ Autorange function on gain ❍ Mounted resonance read-out for transducers ❍ Level monitoring with alarm output ❍ Detector DC output ❍ Wide dynamic range: 100 dB The Measuring Amplifier Type 2525 is a 1-channel low-noise general-pur- pose measurement amplifier with both charge and DeltaTron inputs. The amplifier has a built-in screen for viewing measurement data as well as for selecting set-up and meas- urement parameters (see Fig.1). Measurement data can be viewed in three different formats: full-screen featuring measurement values and a bar graph, large format digits alone, and a digits and select options allow- ing viewing of measurement results simultaneously with set-up and pa- rameter adjustment. The two interface connections on the amplifier’s rear panel (see Fig.2) are for connection via IEEE – 488 or serial interface.
