Machinery Monitoring and Protection System
3500 Machinery Protection Systems
The 3500 system is the world-leader at detecting and preventing both missed-trips and false-trips in rotating machinery. With over 85,000 installed worldwide, it provides automatic protection value by tripping monitored machines to prevent expensive damage when needed.
The 3500 system also protects your machines and processes against false-trips that could bring your operation down for no reason, resulting in a costly outage or loss of production.
When connected with our System 1† software, it also provides continuous condition monitoring information for use in a proactive maintenance program.
The 3500 system incorporates the industry’s most extensive selection of machinery measurement parameters combined with software configuration for virtually all machinery monitoring scenarios.
3500 Machinery Protection System Speed Monitors
The TACH100 Digital Tachometer can serve as a stand-alone speed indicator or in conjunction with any permanently installed monitoring system as a remote speed indicator. The compact unit contains its own power supply, which is convenient when a permanent monitoring system is located at a distance or proximity to the machine is needed to indicate speed. The Digital Tachometer provides a local display indicating machine speed on the machine deck. When double-hearing protection is required, the Digital Tachometer provides a visual indication. Wires can connect in parallel with Keyphasor Proximity Probe input on the monitor rack or directly to the Keyphasor† Proximity Probe. The TACH100 accepts signal and common wires from externally-powered Keyphasor Proximity Probe.
Our 3500/25 Keyphasor Module provides phase reference information in a 3500 rack (you can employ up to four Keyphasors per 3500 rack), enabling advanced machinery diagnostics. It receives input signals from proximity probes or magnetic pickups and converts the once-per-turn or multiple-event-per-turn pulse signals to a precise digital timing measurement. This allows your 3500 system to measure machine speed and vector parameters such as 1X vibration amplitude and phase that are key in determining vital machine behaviors. The Keyphasor measurement is also an integral part of the Bently Nevada† Turbine Supervisory Instrumentation (TSI) suite of sensors specifically for steam turbines. The 3500 System is available as a SIL 2-rated system and with multiple Hazardous Area and country-specific approvals available to tackle any environment.
Our 3500/50M Tachometer Module features 2 channels which accept input from Proximitor probes or magnetic pickups to measure shaft rotating speed, rotor acceleration, or reverse rotation. The 3500/50M Tachometer conditions the inputs and compares the conditioned signals with user-programmable set points that can drive alarms and relay logic in the 3500 relay modules. Alarm options offered with 3500 Rack Configuration software include Speed Band, Zero Speed, Rotor Acceleration and Reverse Rotation. The Keyphasor and speed measurements are also an integral part of the Bently Nevada Turbine Supervisory Instrumentation (TSI) suite of sensors for steam turbines. The 3500 System is available as a SIL 2 rated system and with multiple Hazardous Area and country-specific approvals available. External terminations and internal barrier versions are also available. You should note that the 3500/50M is not designed for Overspeed Detection.
