Bently Nevada 3500 Machinery Protection System: Functional Safety (FS) Certified Products
Functional Safety (FS) certified products provide additional assurance to users that the products will provide the necessary availability to serve as safety
systems to initiate automatic shutdown of critical production machinery by detecting machinery conditions that precede hazardous failure. Bently Nevada
FS certified products give users a way to better document and enable compliance of plant processes with IEC 61511 and IEC 61508.
The Bently Nevada 3500 Machinery Protection and Monitoring System offers a broad range of Functional Safety Certifications ranging from SIL 1 to SIL 2 across multiple protective and safety functions. This data sheet is intended to provide a summary of these SIL certified offerings. Please contact your Bently Nevada
representative for more detailed information.
Functional Safety (FS) certified products typically require conditions of use and specific implementation parameters that are described in the SIL certificate, SIL test report, or associated FS product safety manuals. Certificates, test reports, and applicable FS product safety manuals are available from Bently Nevada and should be referred to during planning and deployment of an FS system.
Functional Safety Certified Products:
The 3500/53_SIL3 Overspeed Detection System is now replaced by the
3701/55 ADAPT.ESD for all new installations. The 3701/55 ADAPT.ESD is
a Triple Redundant system available with SIL 3 certification that serves
as both an emergency shutdown device and an overspeed detection
SIL 1 radial vibration, thrust position, and casing (seismic) vibration using
the 3500/40_SIL and 3500/42_SIL in a simplex configuration with either
3500/32_SIL1 4-Channel Relay Module or 3500/33_SIL1 16-Channel
Relay Module. Sensors for the SIL 1 system may be 3300XL Proximity
Transducer Systems or 350500 or 330525 Velomitors*.
SIL 1 and SIL 2 options for temperature and SIL 1 for process variable
monitoring using the 3500/60_SIL1, 3500/60_SIL2, 3500/61_SIL1, or
3500/62_SIL2 Temperature Monitors or the 3500/62_SIL1 Process
Variable Monitor are available. 3500/32_SIL1, 3500/32_SIL2,
3500/33_SIL1, or 3500/33_SIL2 relay modules may be used to complete
the functional safety certified temperature or process variable system.
Full SIL 2 reciprocating compressor protection using the 3500/70_SIL2
Impulse Velocity, 3500/72_SIL2 Rod Position, or 3500/77_SIL2 Cylinder
Pressure Monitors. Additionally the 3500/60_SIL2 or 3500/61_SIL2
temperature monitors, 3500/32_SIL2 or 3500/33_SIL2 relay modules,
and the 3500/25_SIL2 Keyphasor* module may be selected as needed.
The SIL 2 sensors are the 3300XL 8mm and 11mm Proximity Transducer
Systems and 330500, 190501, 330400, and 330425 seismic transducers
also support a fully SIL 2 certified reciprocating compressor protection
