        Overview Manuals Specifications Application Firmware & Updates Configuration & Programming

        Features:

        • Accepts proximity, velocity, and acceleration transducers; channels programmed in pairs; up to two functions per channel pair; multiple static values (Direct, Gap, 1X, 2X, Not 1X, Smax).
        • Alert and danger setpoints adjustable 0‑100% of full scale; 4-20 mA recorder outputs per channel (0.3662 μA/bit resolution, 100 ms update); buffered transducer outputs for external analysis.
        • ATEX Zone 2, IECEx, Class I Division 2 approvals; operating temperature -30°C to +65°C; 95% non‑condensing humidity; 0.91 kg, 1 front slot.
        The 3500/42 176449-02 is a versatile four‑channel monitor that accepts inputs from both proximity (eddy current) and seismic (velocity/acceleration) transducers. This allows a single monitor to handle a wide range of machinery protection measurements: radial vibration (shaft relative), thrust position, differential expansion, eccentricity, case vibration (velocity/acceleration), and REBAM (rolling element bearing analysis). Channels are programmed in pairs, and each pair can perform up to two functions simultaneously.

        The 3500/42 176449-02 provides comprehensive alarm capabilities essential for machinery protection. Using the 3500 Rack Configuration Software, engineers can set alert setpoints (0‑100% of full scale) for each static value and danger setpoints for any two active static values. Alert delays are adjustable from 1 to 60 seconds in 1‑second intervals; danger delays can be set to 0.1 second or from 1 to 60 seconds in 0.5‑second intervals. This flexibility allows fine‑tuning to avoid nuisance alarms while ensuring rapid response to genuine faults. For integration with plant DCS or PLC systems, each channel provides a 4‑20 mA recorder output proportional to the monitor’s full‑scale measurement.

        Industrial machinery is often located in hazardous environments where flammable gases or dust may be present. The 3500/42 176449-02 is certified for use in Class I, Division 2 (cNRTLus) and ATEX/IECEx Zone 2 (Ex nA nC ic IIC T4 Gc) locations when installed with the appropriate I/O modules and per the referenced installation drawings (138547, 149243, 149244). This allows the monitor to be installed directly in the protected area without external barriers, simplifying system design and reducing installation costs.

        The 3500/42 176449-02 Bently Nevada Seismic Monitor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL)by the manufacturer (OEM).

        • Channel Pairing: Note that channels are typically programmed in pairs (e.g., Channels 1 & 2 share one function, while 3 & 4 can share another or the same).
        • System Integration: Configuration includes setting up the 4 to 20 mA proportional outputs for each channel to communicate with external DCS or PLC systems.
        Description
        The 3500/42 176449-02 is a four-channel monitor that accepts inputs from proximity (eddy current) and seismic (velocity or acceleration) transducers. It conditions these signals to provide vibration and position measurements, comparing them against user-programmable alarm setpoints to drive alarms. 

        When using the 3500/42 176449-02, channels are programmed in pairs and can perform up to two functions simultaneously (e.g., radial vibration on channels 1/2 and thrust position on channels 3/4). The monitor provides various static values (Direct, Gap, 1X Amplitude, 2X Amplitude, Not 1X, Smax, etc.) depending on configuration. 

        The 3500/42 176449-02 consumes 7.7 watts typical and has a front panel with OK, TX/RX, and Bypass LEDs. It provides buffered transducer outputs on coaxial connectors (one per channel) with 550 Ω output impedance. Recorder outputs provide 4-20 mA signals proportional to monitor full scale, with 0.3662 μA per bit resolution and approximately 100 ms update rate. 

        For legacy Bently Nevada 3500 rack system expansions or repairs, the 3500/42 176449-02 is a direct replacement monitor. It requires 3500/01 software version 2.50 or later. The monitor operates from -30°C to +65°C (with external termination I/O module) and is certified for hazardous areas (Class I, Division 2; ATEX Zone 2).

        Technical notes
        The 3500/42 176449-02 channels are programmed in pairs. For example, channels 1 and 2 can perform radial vibration while channels 3 and 4 perform thrust position, or all four channels can perform the same function. Each channel pair can run up to two functions simultaneously.
