Application-Specific FAQ
Q: Can the 3500/64M monitor both surge and rotating stall simultaneously?
A: Yes. With 4 independent input channels, the module can simultaneously monitor multiple pressure taps at different compressor stages, enabling detection of both surge onset and rotating stall patterns within a single module.
Q: Is the 3500/64M compatible with older 3500 racks?
A: The 3500/64M is designed for the standard 3500 rack backplane. Compatibility with specific rack revisions should be confirmed against the Bently Nevada hardware compatibility matrix. Contact us and we will verify compatibility for your existing installation.
Q: What transducer types are compatible with this monitor?
A: The 3500/64M accepts signals from dynamic pressure transducers with appropriate signal conditioning. Common compatible sensors include ICP®-type (IEPE) piezoelectric pressure transducers. Sensor selection should be matched to the expected pressure range and frequency content of the application.
Q: Can this module be used in a SIL-rated safety instrumented system?
A: The 3500 platform supports SIL-rated applications when configured in accordance with the relevant Bently Nevada functional safety documentation and IEC 61511 requirements. Consult your functional safety engineer for SIL verification.
Q: Do you offer exchange or repair services for the 3500/64M?
