350050M-SIL

Product Description

It provides continuous online monitoring of machinery vibration and position, with SIL (Safety Integrity Level) certification for use in safety-instrumented systems. The module accepts inputs from proximity transducers (eddy-current) and accelerometers, and can be configured for radial vibration, axial position, or differential expansion measurements. It features dual voting (1-out-of-2) for critical applications, ensuring high availability and safety. The 3500/50M-SIL operates in a 3500 rack with a dedicated power supply and communication modules. It supports both internal and external (via 3500/20) communication interfaces, allowing integration with distributed control systems (DCS) and plant asset management software. The module provides relay outputs for alarm and danger conditions, and can be configured via the 3500 Rack Configuration Software. Its SIL rating enables use in safety functions up to SIL 2 per IEC 61508. This monitor is commonly used in turbomachinery, compressors, pumps, and other rotating equipment in industries such as oil & gas, power generation, and petrochemical. It offers high reliability and accuracy, with a frequency response from 0.5 Hz to 10 kHz. The module is hot-swappable, allowing replacement without shutting down the monitoring system. With its robust design and advanced diagnostics, the 3500/50M-SIL ensures optimal protection of critical assets. The Bently Nevada 3500/50M-SIL is a 4-channel vibration monitor designed for use in the 3500 series monitoring system.

Technical Specifications

Version & Model Difference

The 3500/50M-SIL is the SIL-certified version of the standard 3500/50M monitor. The main difference is the addition of safety-related firmware and hardware features that allow it to be used in safety-instrumented functions up to SIL 2. It includes enhanced self-diagnostics and a dedicated safety logic solver interface. The standard 3500/50M does not have SIL certification and is intended for non-safety monitoring applications. Both versions are mechanically and electrically compatible with the same 3500 rack, but the SIL version requires specific configuration and documentation for safety use.
