Quasi-static pressure monitoring
PROCESSING MODES AND APPLICATIONS
Principal features:
• HP and LP cut-off frequencies for band-pass filtering can be set in the range 0.1 Hz to
10 kHz
• HP/LP ratio: up to 500
• Slope: up to 60 dB/octave
• Cut-off frequency: defined at 0.1 dB
• Unity gain: max. ±0.3 dB
• Pass-band ripple: ±0.1 dB
• Stop-band rejection: min. 50 dB
• Pressure processing (mbar, bar, psi, Pa) => pressure unit (mbar or bar or psi or Pa)
• User-defined input unit => User-defined output units (scaled 1 to 1).
The processing selects for output two parameters per channel. Each can be expressed as a
rectified value of the type (True) RMS, (True) Mean, (True) Peak or (True) Peak-Peak. In
addition, the following scaled RMS values are available: Scaled Mean, Scaled Peak.
Any of the four pressure units (mbar, bar, psi, Pa) can be selected, provided the unit is defined
for the input channel.
7.13Quasi-static pressure monitoring
This type of processing is equivalent to that used for absolute housing expansion processing
(see 7.10 Absolute housing expansion).
