The Bently Nevada 2300/20-00, also cataloged as the 2300/20 Vibration Monitor Protection Unit, operates as a dedicated hardware component for continuous machinery protection and dynamic signal processing within 2300 Series monitoring architectures.

Model Number Structure

• 2300/20: Base dual-channel vibration and speed monitor unit.
• -00: Standard order option code denoting default hardware package, mounting hardware, and standard firmware setup without hazardous area regional certifications.

System Specifications

Eddy-Current Probe Scaling & Rotor Dynamics

The 2300/20-00 processes raw dynamic signals from proximity sensors requiring gap voltage validation targeted at -10 VDC to verify correct probe position relative to the shaft surface. Signal processing circuits maintain high signal-to-noise ratios, providing cross-talk suppression between channels during high-frequency shaft oscillation. This hardware architecture supports 1X vibration tracking and phase angle detection using the dedicated speed channel, enabling detailed rotor dynamics analysis across operating speed ranges.

Ordering Information

Cabinet Installation Specifications

• Mount the unit vertically on standard DIN-rails or directly on a panel surface to allow convection cooling.
• Maintain minimum 50 mm clearance above and below the chassis for ambient airflow.
• Route dynamic signal cables inside grounded metallic conduits separate from high-voltage AC mains wiring.
• Connect shield wires to the dedicated chassis ground point at one end only to stop ground loops.
• Tighten field terminal block screws to a maximum torque rating of 0.5 Nm.

Technical Questions & Answers

• How is gap voltage configured for proximity probes connected to this unit?

  The transducer channel accepts standard -24 VDC powered proximity probes calibrated for -10 VDC nominal gap voltage center targets.

• What output types are available for external interlocks?

  The unit incorporates integrated dry-contact programmable relay outputs that drive automated equipment shutdown loops.

• Does the module support isolated analog outputs?

  Configurable 4-20 mA DC analog outputs provide real-time trend signal transmission directly to DCS or PLC analog inputs.

• Can the dynamic input channels accept piezo-velocity transducers?

  Yes, the input channels configure via software to interface with Velomitor piezo-velocity sensors or standard accelerometers.

• What supply voltage range must be provided to the terminal connectors?

  The unit requires a filtered DC input supply operating within the range of 18 to 36 VDC at 7.5 Watts maximum power.

• How are frequency passbands defined within the DSP circuit?

  Digital filters set lower and upper cut-off frequencies anywhere within the total hardware bandwidth of 0.2 Hz to 20 kHz.

• What is the purpose of the third input channel on the terminal block?

  The dedicated speed input reads tachometer pulse signals to measure rotational velocity and establish phase reference vectors.

• How is signal cable shielding landed at the monitor terminal block?

  Shield wires must land on designated SHIELD terminals on the unit and remain floating at the sensor housing end.
