Product Overview
The BENTLY 2300/25-00 is a robust proximity transducer system designed for precise measurement of shaft vibration, displacement, and position in rotating machinery. As a core component of Bently Nevada’s machinery protection portfolio, this system excels in applications requiring non-contact, high-resolution data acquisition, such as turbine overspeed prevention and bearing health monitoring. The BENTLY 2300/25-00 is engineered to deliver reliable performance in harsh environments, making it indispensable in power generation, oil & gas, and heavy industrial sectors.

At its core, the system combines a proximity probe, extension cable, and preamplifier module to convert mechanical motion into electrical signals with sub-micron accuracy. Its dynamic range (±500 μm to ±2000 μm) accommodates varying machinery sizes, while automatic calibration ensures consistent readings across operating temperatures. The BENTLY 2300/25-00 supports both radial and axial measurements, enabling early detection of misalignment, imbalance, and thermal bow in critical assets. Compared to alternative solutions, its hermetic sealing and MIL-STD-810G compliance guarantee survival in explosive or corrosive atmospheres, such as offshore platforms or chemical plants.

Technical Specifications

Key Features and Benefits
The BENTLY 2300/25-00 thrives in extreme conditions with its titanium probe housing and polyurethane-coated cables, resisting abrasion from high-speed machinery (up to 30,000 RPM). Its preamplifier incorporates adaptive gain control, automatically adjusting sensitivity to optimize signal-to-noise ratio. For diagnostics, the system supports real-time gap voltage monitoring, alerting operators to probe tip wear or target surface degradation.

Integration with Bently’s 3500 rack system enables centralized data logging and alarm management, while compatibility with third-party PLCs (e.g., Siemens S7, ABB AC800M) simplifies retrofits. The system’s low-noise design (<0.1% THD) ensures accurate readings even in electrically noisy environments, such as near variable frequency drives (VFDs). Compared to competitors like Brüel & Kjær’s 8309 or Metrix’s MX800, the BENTLY 2300/25-00 offers superior temperature tolerance and faster response times (≤1 μs), critical for transient event capture.

Application Scenarios
In power plants, the BENTLY 2300/25-00 monitors steam turbine shaft vibrations, detecting subsurface cracks before they escalate into catastrophic failures. In LNG terminals, it safeguards cryogenic pump bearings, preventing seal leaks that could ignite flammable vapors. For aviation test cells, the system tracks jet engine rotor displacement during spin-up, ensuring compliance with API 670 standards.

The system’s ATEX Zone 0 certification makes it ideal for oil rig mud pumps, where explosive gas mixtures demand intrinsically safe equipment. In pulp mills, it protects calendar roll drives, avoiding web breaks that waste tons of paper. Even in HVAC chillers, the BENTLY 2300/25-00 ensures compressor reliability, preventing refrigerant leaks that degrade energy efficiency. Across these applications, the system’s precision reduces maintenance costs by up to 40% through predictive interventions.

Installation and Maintenance
Before installing the BENTLY 2300/25-00, verify the probe’s thread compatibility with the target machinery (M10 x 1.5 standard). Mount the probe at a 45° angle to the shaft to avoid oil film interference, ensuring a 1.5mm air gap for optimal signal strength. Route cables through EMI-resistant conduit and avoid sharp bends to prevent signal attenuation. During commissioning, use Bently’s ADAPT software to perform gap voltage calibration (–9.75 VDC nominal).

For maintenance, inspect probe tips annually for wear and clean with lint-free wipes. Perform quarterly functional tests using a micrometer to validate measurement accuracy. Replace preamplifiers every five years to avoid component drift. In high-vibration environments, schedule semi-annual spectral analysis to detect resonance issues. Proper care ensures the system operates reliably for over 15 years, aligning with Bently Nevada’s longevity standards.
