Introduction to the Bently Nevada 2300/25 Condition Monitoring Kit

The 2300/25_KIT-001-00 from Bently Nevada is a complete condition monitoring system kit. This kit provides everything needed for machine protection monitoring. Engineers use the 2300/25_KIT-001-00 to measure vibration, speed, and temperature on rotating machinery. Its compact design suits both hazardous and non-hazardous locations. Furthermore, the kit includes two accelerometer sensors for immediate installation.

Kit Configuration Overview

Configuration 001 defines the specific contents of this kit. The 2300/25_KIT-001-00 includes one 2300/25 monitor as the core component. Two accelerometer sensors (model 200350) are provided for vibration measurement. Additionally, two 17 ft (5.2 m) cables (model 9571) connect the sensors to the monitor. A 6 ft (1.8 m) shielded Ethernet cable enables network communication. For housing, two options are available depending on the area classification. The kit excludes the Keyphasor sensor and 24V DC power supply.

Housing Options

Two housing options come with this kit based on configuration. For non-hazardous areas, the fiberglass housing (105M6193-01) is included. For hazardous areas, the stainless steel housing (105M6193-03) is provided instead. Housing dimensions measure 18.03 x 15.04 x 6.3 inches. These enclosures protect the monitor from environmental damage. Therefore, the 2300/25_KIT-001-00 suits various installation environments.

Power Input Specifications

The 2300/25_KIT-001-00 monitor accepts DC power input from 18 to 36 Vdc. Maximum power consumption is only 7.5 watts. This low power draw suits remote or solar-powered installations. The monitor requires a separate 24V DC power supply. Consequently, users must provide their own power source for operation.

Channel Types and Configuration

Multiple channel types are supported by the 2300/25 monitor. ICP accelerometers connect directly for vibration measurement. The bandpass filter is configurable from 0.2 Hz to 20 kHz. Scale factor range spans 5 to 1000 mV/g for flexibility. Full scale range reaches 2 to 80 g peak acceleration. For velocity measurements, scale factor ranges from 5 to 1000 mV/in/s. Radial vibration supports scale factors from 5 to 1000 mV/mil. Thrust channel scale factors also range from 5 to 1000 mV/mil. Independent 24-bit ADCs on each input channel ensure high accuracy. Overall accuracy stays within ±1% of full scale range for the 2300/25_KIT-001-00.

Speed and Keyphasor Input

Keyphasor transducers are supported for speed measurement. Multiple events per revolution can be processed by the monitor. Event ratios are configurable for speed inputs up to 20 kHz. Threshold voltage resolution reaches 0.1 Vdc for precise triggering. RPM range extends from 1 to 120,000 revolutions per minute. Therefore, the 2300/25_KIT-001-00 handles high-speed machinery applications.

Proximity Transducer Interface

The proximity transducer interface provides a supply voltage from -22.8 to -25.2 Vdc. Maximum rated current reaches 15 mA for connected sensors. Short circuit current ranges from 15.1 mA to 23.6 mA for protection. Accuracy holds at ±1% of full scale range. Input impedance measures 10 kΩ for 3-wire voltage mode. For proximity switch interface, supply voltage ranges from -10 to -24 Vdc. The lower not OK limit is set at -2.75 ±0.05 V. RPM range for proximity switches spans 1 to 60,000 rpm.

Other Input Types

Magnetic pickups are also supported by the 2300/25_KIT-001-00. Input voltage adapts to sensor model 284947 output characteristics. RPM range for magnetic pickups spans 200 to 120,000 rpm. Three contact inputs provide additional monitoring capabilities. These contacts support configuration lock, latched alarm reset, and monitor bypass functions. Activation requires 0 to 10 kΩ resistance. De-activation occurs from 150 kΩ to infinite resistance. An external button also resets latched alarms and relays.

Outputs and Relays

Three buffered outputs are available through BNC connectors on the monitor. Two vibration outputs provide raw signal access for analysis. One speed output delivers tachometer signals to other systems. Relays provide two dry-contact outputs for external alarm indication. These relays may be normally energized or de-energized by configuration. Contact life reaches 100,000 cycles at 5 amps, 250 Vac. For DC loads, 200,000 cycles at 1 amp, 24 Vdc is typical. Maximum switched contact voltage is 250 Vac or 250 Vdc. Maximum breaking contact current reaches 6 A at 250 Vac or 6 A at 24 Vdc. For hazardous areas, maximum switched values are derated appropriately.

SPA Output Specifications

The SPA output on the 2300/25_KIT-001-00 provides additional signal capabilities. Input signal range includes High AC at 8 Vpp and Low AC at 1.6 Vpp. DC GAP range spans 0 to -20 Vdc. Accuracy for High/Low AC is ±1% of full scale at 100 Hz. DC GAP accuracy is ±0.5 V with measurable AC accuracy at ±20 mV. Frequency response ranges from 10 Hz to 3000 Hz within ±5%.

LED Indicators

Comprehensive LED indicators provide clear monitor status at a glance. The OK LED indicates when the monitor is operating properly. Protection fault LED signals hardware faults impacting alarm determination. User inhibit LED shows alarms and relays intentionally inhibited. Bypass LED indicates user-initiated bypass action. Relay status LED shows if relays have been activated. TX/RX LED indicates Ethernet status and remote software communication. SPEED/AUX channel status LED shows valid speed signal input. Alert LED engages if any channel is in alert state. Danger LED engages if any channel reaches danger state. The LCD display allows viewing machine speed, vibration values, setpoints, and configuration.

Communications

Ethernet communication uses 10Base-T and 100Base-TX standards. The interface conforms to IEEE802.3 specifications. An RJ-45 connector accepts standard Ethernet cabling. Maximum cable length reaches 100 meters (328 feet). The 2300/25_KIT-001-00 communicates with System 1 software for data analysis.

Environmental Limits

Operating temperature ranges from -30°C to +65°C (-22°F to +149°F). Storage temperature spans -40°C to +85°C (-40°F to +185°F). Humidity tolerance reaches up to 95% non-condensing. Vibration limitation is 3 g for reliable operation. Battery life for the real-time clock reaches 38 years powered at 50°C. Un-powered battery life extends to 12 years at 50°C. Therefore, the 2300/25_KIT-001-00 suits harsh industrial environments.

Data Storage Capabilities

Trend measurements are stored at configurable intervals. Pre-event data stores 10 minutes at 1 second intervals. Additional pre-event data stores 20 seconds at 100 millisecond intervals. Post-event data stores 10 seconds at 100 millisecond intervals. One minute of post-event data stores at 1 second intervals. Spectrums and waveforms also have dedicated storage. Pre-event spectra store 2.5 minutes at 10 second intervals. Post-event spectra store 1 minute at 10 second intervals. During network disruptions, the 2300 stores at least 5 alarm data captures. This requires System 1 Evolution 21.1 or newer and firmware release 3.2 or newer.

Physical Dimensions

Dimensions measure 127 mm wide by 127 mm deep by 76.2 mm high. In imperial units, this equals 5 x 5 x 3 inches. Weight is 1.03 kg or 2.26 lbs. Mounting options include panel mount or DIN rail. A DIN rail adapter is included with the 2300/25_KIT-001-00.
