Product Overview

The Bently Nevada 87900-01 functions as the specialized Front Panel Assembly for the 3300 Series Dual Setpoint Dual Monitor (DSDM). This interface component provides critical local visibility and physical access to the 3300 system’s monitoring logic. It houses the display indicators and manual override controls necessary for operators to observe real-time machinery vibration levels and manage alarm setpoints directly at the rack. We supply this unit as 100% Brand New and Original in Factory Packing, ensuring the tactile and visual integrity of your legacy machinery protection system.

Technical Specifications

Engineering Advantages

• Optimized Local Interface: The 87900-01 provides immediate access to the "Danger" and "Alert" setpoint status. This local display allows field technicians to verify monitor health and vibration levels without requiring an external computer or DCS connection.

• Eddy Current Signal Integrity: The panel supports the high-frequency response (DC to 10 kHz) required for eddy current proximity measurements. It ensures that the conditioned voltage signal from the Proximitor reaches the monitoring logic without attenuation or distortion.

• Rugged Faceplate Durability: Bently Nevada constructs this panel to withstand the chemical exposure and thermal cycling typical of petrochemical and power plant environments. The industrial-grade overlays resist fading and mechanical wear during long-term service.

• Dual-Channel Clarity: As a DSDM (Dual Setpoint Dual Monitor) component, the panel facilitates the simultaneous monitoring of two independent channels. This allows for clear, distinct observation of X and Y radial vibration or redundant axial position measurements.

• Direct Legacy Restoration: Replacing a damaged or clouded front panel with an original 87900-01 restores the readability and tactile response of the 3300 rack. This ensures that operators can make critical safety decisions based on clear, accurate local indications.

FAQs

• Can I use the 87900-01 with a standard 3500 series monitor?

  No. The 87900-01 is specifically engineered for the 3300 Series Dual Setpoint Dual Monitor (DSDM). The 3500 series uses a completely different physical form factor and digital display architecture.

• Does this part number include the internal monitoring electronics?

  The 87900-01 typically refers to the Front Panel Assembly. While it includes the display and interface hardware, it works in conjunction with the main monitor PWA (Printed Wiring Assembly) housed inside the 3300 rack.

• How do I ensure compatibility with my existing 3300 XL probes?

  This front panel assembly supports signals conditioned by Proximitors calibrated for 3300 XL probes. As long as your internal monitor card matches your probe type, the 87900-01 will accurately display the linear range and alarm status.

• Is this a refurbished or "pulled" part?

  We guarantee this unit is 100% Brand New and Original. It ships in factory-sealed packaging, ensuring that all switches and indicators meet original OEM specifications for machinery protection.
