Bently Nevada 2300/20-00 is the no-agency-approval version of the 2300/20 compact vibration monitor, a two-channel device for continuous condition monitoring and machinery protection on essential medium- to low-criticality and spared equipment. The 2300/20 form is distinguished by two configurable 4-20 mA outputs; the standard monitor order includes its DIN-rail mount, manual and configuration software.
- Power input: 18 to 36 VDC, 7.5 W maximum
- Primary vibration inputs: Two synchronized acceleration, velocity or proximity inputs
- Input conversion: Independent 24-bit ADCs; channel hardware accuracy ±1% of full scale
- Acceleration input: Configurable 0.2 Hz to 20 kHz bandpass; 5 to 1000 mV/g scale factor; 2 to 80 g peak full scale
The monitor accepts two synchronously sampled acceleration, velocity or proximity-transducer inputs plus a dedicated speed channel that can use a proximity probe, magnetic pickup or proximity switch. All three input channels can instead support process variables, and configured measurements include acceleration peak/RMS, velocity peak/RMS, displacement peak-to-peak/RMS and speed with alert and danger alarming. For plant integration, 2300/20-00 provides two internally powered 4-20 mA outputs, two programmable dry-contact relay outputs, three protected BNC buffered outputs for the two vibration signals and speed/Keyphasor signal, and 10/100Base-T Ethernet with Modbus over Ethernet. Companion hardware can include Bently Nevada accelerometers, Velomitor or Proximitor systems, a compatible speed sensor, a 24 VDC DIN-rail supply, an enclosure and optional System 1 device connectivity, all selected separately for the installation. The 2300 platform is applied where a broad machine train or individual casing can be covered by its channel count: proximity sensing on fluid-film-bearing machines, velocity sensing on slow-speed assets, acceleration and enveloped-acceleration measurements on rolling-element bearings or geared equipment, and compact protection on examples such as cryogenic pumps and small hydro units. Baker Hughes lists oil and gas, power generation, water treatment, pulp and paper, manufacturing, mining and cement among the applicable industries; the -00 approval code confines this exact order to locations that do not require the omitted agency approvals.
Important Notice: Confirm the complete physical nameplate, current Bently Nevada documentation, compatible components and installed-system configuration before installation or replacement.

Compact balance-of-plant machinery protection
Continuously measures two vibration points and a speed or process input, alarms on configured levels and can operate relay outputs for an essential or spared machine whose point count fits the monitor.
Fluid-film-bearing shaft monitoring
Uses compatible Proximitor inputs for radial-vibration or thrust-position measurements, with a phase/speed input for time-synchronous diagnostics.
Slow-speed and rolling-element-bearing monitoring
Uses Velomitor or accelerometer inputs for casing velocity, acceleration and configured enveloped-acceleration measurements on slow-speed, bearing or geared assets.
Small hydro or cryogenic-pump monitoring
Provides a compact continuous monitor for officially documented small-hydro use and for engineered cryogenic-pump acceleration/velocity measurement strategies, subject to sensor and area-approval selection.
Read and follow the current Bently Nevada documentation and host-equipment instructions before work. Verify the complete physical nameplate and system configuration.
1
Treat 2300/20-00 as the approvals-option-00 unit: do not claim or rely on ATEX, IECEx or CSA explosive-atmosphere approval, and do not assume an approved enclosure changes the monitor certification.
2
Supply only 18 to 36 VDC within the 7.5 W maximum requirement, use the documented grounding and enclosure practice, and keep the unit within -30 to +65 °C and non-condensing humidity limits.
3
Connect the two 4-20 mA channels only as internally powered loops; the manufacturer warns that they will not work with an external powered loop, and the connected load must remain within 0 to 600 ohms.
4
Before service, verify each sensor type, excitation, wiring, scale factor, bandpass, speed range, alert/danger setpoint, relay logic and bypass state, then perform the site's required functional test.
5
Use the official operation, field-wiring, software and installation documents for the installed firmware; control configuration access, apply compatible BN Monitor Configuration/System 1 versions, and keep copper Ethernet runs within the 100 m published limit.
