  • strain gauge, amplitude resolution 24 Bit
  • Profibus
  • sampling frequency adjustable 1 Hz ... 1 kHz,
  • storage of statistical sizes, e.g. minimum, maximum or average value, is adjustable between multiple values per minute and one value per hour up
• up to 16 speed inputs, measurement of impulse time point, accuracy 1 ns. Optionally speed input via A/B-Lane with measurement of rotating direction. Alternatively speed input via Profibus
• distributed mounting of signal inputs in the field via LAN (up to 100 m) or fibre optical cable (up to 2 km) possible

Automatic monitoring

• event based diagnosis for two speed ranges and two power ranges per machine
• start of measurements can be controlled via digital inputs, speed input or process input calculation
• calculation of spectra and envelope curve spectra with 32,768 lines, adjustable to 20 kHz, 10 kHz, 5 kHz, 2.5 kHz, 1.25 kHz, 625 Hz, 312.5 Hz and 156 Hz
• order spectra and envelope curve order spectra with 32,768 lines with a speed depending resolution
• automatic detection of significant peaks in spectra, envelope curve spectra, order spectra and envelope curve order spectra by DVS (Drive Vibration Significance analysis)
• characteristic values according to DIN ISO 10816-3
• characteristic values according to VDI-3834 0.1 Hz ... 10 Hz, 10 Hz ... 1 kHz, 10 Hz ... 2 kHz, 10 Hz .. 5 kHz
• online RMS of vibration velocity, vibration acceleration and vibration acceleration of envelope with adjustable filter frequency
• monitoring of threshold exceeding of configured characteristic values and process factors
• generation of found peaks (amplitude and significance, frequency/ order) as diagnostic attributes
• storage of characteristic values in case of an alarm
• storage of spectra, envelope curve spectra, order spectra and envelope curve order spectra in case of an alarm
• storage of time signals in case of an alarm
• measurement data can be saved up to 3 months (adjustable) on the Peakanalyzer
• querying of alarm states over Ethernet
• output of characteristic value alarms and process factor alarms via Profibus or signaling via digital outputs

Alarm dealing

• Alarms can be acknowledged by software. This ensures that the same alarm will only be generated again if there are higher vibration values (indirect tendency monitoring).
