3500/64M 140734-05 Displacement/Velocity Acceleration Monitor

The provided text appears to be a technical description of the signal conditioning features for a specific monitoring device, the 3500/64M Dynamic Pressure Monitor. Here is a breakdown of the key information:

1. Dynamic Pressure Signal Conditioning:
   • Two filtering modes: Low Mode and High Mode.
   • Low Mode:
     • High pass filter: 10-pole (200dB per decade, 60 dB per octave) in the range of 5 Hz to 4 KHz. If no low pass (LP) filter is chosen, the range extends to approximately 5.285 KHz.
     • Low pass (LP) filter: 10-pole (200dB per decade, 60 dB per octave).
     • Fixed low pass (LP) filter: LP = none with a minimum attenuation of -78 dB in the stop band.
   • High Mode:
     • High pass filter: 6-pole (120 dB per decade, 36 dB per octave) in the range of 10 Hz to 14.75 KHz.
     • Low pass filter: 10-pole (200dB per decade, 60 dB per octave).
     • Line rejection (notch) filter: Two settings at 50 or 60 Hz, with a response of -0.175 dB (98%) of Full Scale at the center frequency and -35 dB (1.8%) of Full Scale in a specified range around the center frequency.
2. Cascade Mode:
   • Channels 1 and 2 form one pair, and channels 3 and 4 form another pair. Different bandpass filter options can be selected for each channel within a pair, but both channels within a pair must operate in the same filtering mode.
   • Cascade Mode (1 > ALL) allows feeding only the channel 1 input to all four channels.
3. Filter Quality:
   • Different qualities of filtering are provided in the Low and High modes.
4. Measured Variables:
   • The primary value for each channel is dynamic pressure direct.
5. Physical Dimensions and Weight:
   • Main Board (Monitor Module): 241.3 mm x 24.4 mm x 241.8 mm, weight 0.82 kg (1.8 lb).
   • I/O Modules (non-barrier): 241.3 mm x 24.4 mm x 99.1 mm, weight 0.20 kg (0.44 lb).
   • I/O Modules (with barrier): 241.3 mm x 24.4 mm x 163.1 mm, weight 0.46 kg (1.01 lb).

The information provides details about the frequency ranges, filter types, and other specifications related to the dynamic pressure monitoring capabilities of the 3500/64M device. Users can use this information to configure the device based on their specific requirements for signal conditioning and monitoring.
