The Bently Nevada 2300/25-02 differs from the 2300/20 series by offering SPA outputs. SPA stands for Signal Processing Assembly outputs. These outputs provide high AC, low AC, and DC gap signals.
Therefore, this model works perfectly with older protection systems that expect SPA input signals. It also holds ATEX, IECEx, and CSA certifications for explosive atmospheres.
Additionally, the 2300/25-02 shares the same input specifications as other 2300 series monitors. All transducer inputs remain fully configurable. The only change is the output type from 4-20mA to SPA.
The SPA outputs on the 2300/25-02 include three signal types per channel. High AC output delivers 8 Vpp maximum. Low AC output delivers 1.6 Vpp maximum. DC GAP output ranges from 0 to -20 Vdc.
Accuracy for High AC and Low AC outputs is ±1% of full-scale at 100 Hz. DC GAP accuracy is ±0.5 V. For measurable AC signals, accuracy reaches ±20 mV.
Frequency response spans from 10 Hz to 3000 Hz with ±5% tolerance.
These SPA outputs connect directly to legacy Bently Nevada monitoring systems. No additional signal conditioning is required.
The 2300/25-02 supports multiple input types. For ICP accelerometers, scale factor ranges from 5 to 1000 mV/g. Full scale goes from 2 to 80 g peak.
For velocity sensors, scale factor ranges from 5 to 1000 mV/in/s. Full scale reaches 0 to 50 in/s peak.
For radial vibration using proximity probes, 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.
Each input channel uses an independent 24-bit ADC. Consequently, measurement accuracy remains high across all channels. The overall accuracy rating is ±1% of the full-scale range.
The 2300/25-02 includes a dedicated speed/Keyphasor input. It supports multiple events per revolution and event ratios. Speed input frequency goes up to 20 kHz.
Threshold voltage resolution reaches 0.1 Vdc. RPM range for proximity transducers is 1 to 120,000. For proximity switches, RPM range is 1 to 60,000.
For magnetic pickup sensors, the RPM range is 200 to 120,000. Input voltage adapts to sensor 284947 output automatically.
Three buffered BNC outputs are available on the monitor. Two outputs carry vibration signals, and one carries speed signals.
Furthermore, two dry-contact relays provide alarm or shutdown actions. These relays are epoxy-sealed with a contact life of 100,000 cycles at 5 amps (250 Vac) in non-hazardous areas.
For hazardous area use, relay specifications change. Maximum switched current becomes 6 A at 24 Vac or 5.8 A at 24 Vdc.
Ethernet communication follows IEEE802.3 standards. It supports 10Base-T and 100Base-TX with cable length up to 100 meters.
In case of network disruption, the Bently Nevada 2300/25-02 stores at least five alarm data captures. This requires System 1 Evolution 21.1 or newer.
1. What is the main difference between the 2300/20 and the 2300/25-02?
The 2300/25-02 provides SPA outputs (High AC, Low AC, DC GAP) instead of 4-20mA outputs. All other features remain identical.
2. Can I use the SPA outputs with modern PLC systems?
Yes, but you may need signal conditioning. The SPA outputs were originally designed for legacy Bently Nevada monitoring systems.
3. Is the 2300/25-02 certified for hazardous areas?
Yes, it holds ATEX, IECEx, and CSA certifications for Zone 2 and Division 2 locations.
4. What is the frequency response of the SPA outputs?
Frequency response ranges from 10 Hz to 3000 Hz with ±5% tolerance. This covers most machinery vibration frequencies.
5. How do I reset a latched alarm on the Bently Nevada 2300/25-02?
Use an external button connected to the contact inputs. Alternatively, use the buried button on the monitor or the configuration software.
