Product Introduction

BENTLY 330876-03-90-00-05 is a high-performance proximity transducer system, part of BENTLY NEVADA’s renowned 3300 Series, designed for precise measurement of shaft position, vibration, and speed in rotating machinery. As a critical component in machinery protection systems, this transducer delivers reliable data essential for preventing catastrophic failures in industrial equipment.

Unlike general-purpose sensors, 330876-03-90-00-05 utilizes eddy-current technology to detect metal targets without physical contact, making it ideal for monitoring turbine shafts, motor rotors, and compressor spindles. Its 9-meter cable length provides flexible installation in large machinery, while the 0-25.4 mm measurement range covers most industrial shaft movement requirements. When integrated with controllers like ABB PPC907BE101 3BHE024577R0101, it forms a complete machinery health monitoring system, enabling real-time analysis and predictive maintenance.

Core Advantages and Technical Highlights

Non-contact measurement:

The eddy-current principle of 330876-03-90-00-05 eliminates wear and tear associated with contact sensors, ensuring a service life 5-10 times longer than mechanical probes. In a steam turbine application, this non-contact design prevents shaft damage that could occur with physical sensors, reducing maintenance costs by up to 30% over the equipment lifecycle.

Extreme temperature tolerance:

Operating from -51°C to 177°C, 330876-03-90-00-05 outperforms standard proximity sensors in harsh environments like gas turbine enclosures. In comparison, many industrial sensors fail above 85°C, making this transducer indispensable in high-heat applications where machinery health monitoring is critical.

High accuracy and stability:

With ±1% full-scale accuracy and minimal drift over time, 330876-03-90-00-05 provides consistent measurements even after years of operation. In a power plant’s generator monitoring system, this stability ensures reliable detection of shaft misalignment as small as 0.02 mm—early warning that prevents bearing damage costing hundreds of thousands in repairs.

Rugged industrial design:

The nickel-plated brass housing and 316 stainless steel probe tip resist corrosion and mechanical damage, making 330876-03-90-00-05 suitable for offshore oil rigs and chemical processing plants. Its vibration resistance (10 g peak) ensures accurate readings even in high-vibration environments like reciprocating compressors.

Typical Application Scenarios

In fossil fuel power plants, BENTLY 330876-03-90-00-05 monitors steam turbine shaft displacement, providing critical data on axial and radial movement. The 4-20 mA output connects directly to ABB PPC907BE101 3BHE024577R0101 controllers, which analyze trends to detect incipient bearing wear—often 6-8 weeks before traditional maintenance schedules would identify issues. This early warning capability reduces unplanned downtime by up to 50% in turbine operations.

Within oil refineries, this transducer system is installed on centrifugal compressors, measuring shaft vibration and position to prevent seal failures. The 9-meter cable allows mounting in hazardous areas while routing signals to safe-zone monitoring systems, compliant with ATEX requirements. Operators rely on its stable readings to distinguish between normal vibration and abnormal patterns indicating impeller imbalance.

In paper mills, 330876-03-90-00-05 monitors dryer rolls and press section shafts, where even minor misalignment can cause paper breaks and production losses. Its ability to operate in humid environments (up to 95% RH non-condensing) makes it far more reliable than optical sensors, which often fail due to moisture and dust.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing BENTLY 330876-03-90-00-05, verify the mounting surface can withstand vibration and temperature extremes. Use a calibrated micrometer to set the initial gap (typically 12.7 mm) between the probe tip and target surface. Prepare torque wrench (0.5-1 Nm) for securing the probe housing, and ensure the 9-meter cable is routed away from high-voltage lines to prevent interference. For hazardous areas, confirm the installation location matches ATEX/IECEx zone classification. Connect the MS connector using the supplied mating part, ensuring proper torque (0.8 Nm) to maintain environmental seals.

Maintenance suggestions: Inspect 330876-03-90-00-05 quarterly for probe tip contamination—clean with isopropyl alcohol and a soft cloth if oil or debris accumulate. Check cable integrity for abrasions or kinks, especially near connectors. Perform annual calibration using BENTLY’s 3300 Calibration Kit to verify accuracy within ±1% of full scale. If output drift exceeds specifications, replace the probe rather than attempting field repairs, as internal components are factory-calibrated. Store spare probes in anti-static packaging in a dry environment (-20°C to 60°C).
