The Bently Nevada 2300/20-02 shares the same core features as the standard 2300 series. However, this model includes multiple explosive atmosphere certifications. Specifically, it meets ATEX, IECEx, and CSA standards.
Therefore, you can safely install it in Zone 2, Division 2, or similar hazardous environments.
Additionally, the relay specifications change slightly for hazardous area use. Maximum switched current is 6 A at 24 Vac or 5.8 A at 24 Vdc. All other electrical ratings remain identical to the standard version.
The 2300/20-02 offers flexible input options for various transducer types. It supports ICP accelerometers, Velomitor sensors, and proximity probes.
Furthermore, the device includes a dedicated speed/Keyphasor input with a range up to 20 kHz. Threshold voltage resolution reaches 0.1 Vdc, ensuring precise speed measurement.
Each input channel uses an independent 24-bit ADC. Consequently, measurement accuracy remains high across all channels. The accuracy rating is ±1% of the full-scale range.
For accelerometer channels, the scale factor ranges from 5 to 1000 mV/g. The full-scale range is configurable between 2 and 80 g peak.
For velocity measurements, the scale factor ranges from 5 to 1000 mV/in/s. The full-scale range reaches 0 to 50 in/s peak.
For radial vibration using proximity probes, the scale factor ranges from 5 to 1000 mV/mil. Full scale goes up to 160 mil peak-peak.
The thrust channel also supports a scale factor from 5 to 1000 mV/mil.
Power input requires 18 to 36 Vdc, with maximum power consumption of 7.5 W.
The device operates reliably between -30°C and +65°C. Humidity tolerance is up to 95%, non-condensing.
The 2300/20-02 includes two isolated 4-20mA outputs with internal loop power. Load resistance ranges from 0 to 600 Ω. Resolution is 0.3662 µA, and accuracy stays within 1% over the full temperature range.
Moreover, the monitor provides three buffered BNC outputs. Two are for vibration signals, and one is for speed.
Two dry-contact relays are available for alarm or shutdown actions. These relays are epoxy-sealed and rated for 100,000 cycles at 5 amps (250 Vac) in non-hazardous areas.
Ethernet communication follows IEEE802.3 standards, supporting 10Base-T and 100Base-TX. Cable length can go up to 100 meters.
In case of a network disruption, the Bently Nevada 2300/20-02 stores at least five alarm data captures. This requires System 1 Evolution 21.1 or newer.
Vibration limitation is 3 g during operation. Storage temperature ranges from -40°C to +85°C.
The real-time clock battery lasts 38 years when powered and 12 years unpowered at 50°C.
Dimensions are 127 mm x 127 mm x 76.2 mm (5 x 5 x 3 inches). Weight is 1.03 kg (2.26 lbs).
Mounting options include panel mount or DIN rail. An adapter is included in the package.
First, ensure the 2300/20-02 is installed according to ATEX, IECEx, or CSA requirements. Use approved cable glands and sealing methods.
Next, connect power supply between 18 and 36 Vdc. Verify that the supply is rated for hazardous area use.
For proximity probes, use twisted pair cables with proper shielding. Connect the shield only at the monitor end.
Additionally, set the jumpers between COM and chassis ground when required. This reduces electrical noise in sensitive environments.
For the 4-20mA outputs, do not connect external loop power. The 2300/20-02 provides internal power only.
Finally, configure the monitor using the included software. An Ethernet connection is recommended for easy setup.
1. Can I use the 2300/20-02 in Zone 1 hazardous areas?
No, this model is certified for Zone 2 and Division 2 only. For Zone 1, please check other Bently Nevada models.
2. Does the certification affect any electrical specifications?
Only the relay ratings differ in hazardous areas. Maximum switched current becomes 6 A at 24 Vac or 5.8 A at 24 Vdc.
3. What happens if Ethernet communication fails?
The monitor stores up to five alarm data captures locally. Data is not lost during short network disruptions.
4. How do I reset a latched alarm on the 2300/20-02?
Use an external button or the buried button on the monitor. The configuration software also allows reset commands.
5. Is special wiring required for the 4-20mA outputs in hazardous areas?
Yes, use certified intrinsic safety barriers if required. The 4-20mA outputs themselves are not intrinsically safe.
