Product introduction

The 330103-00-04-10-02-00 from Bently Nevada is a high-performance velocity sensor, designed to measure vibration in rotating machinery by converting mechanical motion into proportional electrical signals. As a core component in Bently Nevada’s 3300 series vibration monitoring ecosystem, this sensor provides critical data on machinery health, enabling detection of imbalance, misalignment, and bearing degradation in industrial equipment.

Unlike accelerometers that measure acceleration, the 330103-00-04-10-02-00 directly measures vibration velocity—often the most useful parameter for assessing overall machinery condition. Its moving-coil design generates an AC voltage proportional to vibration speed, making it ideal for monitoring motors, pumps, fans, and turbines in power generation, manufacturing, and processing industries. When paired with compatible signal conditioners like the 125720-01 and mounting hardware, it forms an essential part of predictive maintenance programs, providing reliable vibration data for early fault detection.

Core advantages and technical highlights

Velocity-specific measurement: The 330103-00-04-10-02-00 is optimized for velocity measurement (10Hz to 1000Hz), capturing the frequency range most relevant to general machinery health assessment. Its 100mV/mm/s sensitivity provides accurate output for analyzing vibration patterns associated with common machinery issues, including unbalance, misalignment, and looseness. This direct velocity measurement eliminates the need for integration from acceleration data, simplifying signal processing requirements.

Industrial durability: Encased in a hermetically sealed stainless steel housing, the 330103-00-04-10-02-00 withstands harsh industrial environments, including exposure to moisture, dust, and temperature extremes (-54°C to 121°C). Its rugged construction resists shock up to 1000g and vibration up to 20g, ensuring reliable operation in high-vibration machinery applications. The sensor’s design minimizes sensitivity to temperature changes, maintaining measurement accuracy across its operating range.

Stable output characteristics: The 330103-00-04-10-02-00 delivers consistent sensitivity with minimal drift over time, reducing the need for frequent recalibration. Its moving-coil design provides low noise output and excellent linearity across the 0-25mm/s measurement range, ensuring accurate detection of both subtle vibration changes and larger amplitude events. The integral shielded cable minimizes electromagnetic interference (EMI) from nearby electrical equipment.

Flexible installation: With its 10-32 UNF stud mount and optional magnetic base, the 330103-00-04-10-02-00 offers versatile installation options on various machinery surfaces. The 4m integral cable provides sufficient length for routing to control cabinets, while the strain-relieved connector protects against cable fatigue in vibrating environments. This flexibility allows optimal placement on bearing housings and other critical measurement points.

Typical application scenarios

In power generation plants, the 330103-00-04-10-02-00 is installed on turbine bearings and generator end shields to monitor vibration velocity. Its frequency response captures the critical range for detecting rotor imbalance and bearing defects in large rotating equipment. The sensor’s robust construction withstands the thermal cycling and electrical noise common in power plant environments, providing reliable data to the plant’s machinery protection system.

Within chemical processing facilities, the 330103-00-04-10-02-00 monitors pump and compressor vibration, with installations on both driver and driven equipment. Its ATEX certification allows safe operation in potentially explosive environments, while the hermetic sealing protects against chemical vapors. The velocity data helps detect mechanical issues early, preventing process interruptions and ensuring safe operation of critical processing equipment.

In manufacturing facilities, the 330103-00-04-10-02-00 provides cost-effective vibration monitoring of production line motors, gearboxes, and conveyors. When paired with the 125720-01 signal conditioner, it converts vibration velocity into 4-20mA signals for the plant’s PLC system, enabling automated alerts for abnormal vibration levels. This implementation helps maintenance teams address machinery issues before they cause production downtime.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the 330103-00-04-10-02-00, select a mounting location on the machine casing near bearing housings for optimal vibration transfer. Ensure the surface is clean, flat, and free of paint or corrosion. For hazardous area installations, verify the location classification matches the sensor’s ATEX Zone 2 rating. Plan cable routing to avoid sharp bends, moving parts, and electromagnetic interference sources, maintaining the minimum bend radius of 15mm.

Mounting procedure: Secure the 330103-00-04-10-02-00 using the 10-32 UNF stud, torquing to 2.5 Nm (22 in-lbs) for proper vibration transfer. For temporary measurements, use the optional magnetic base, ensuring full contact with the machine surface. Connect the integral cable to a compatible signal conditioner or junction box, ensuring the connector is fully seated and locked. Route the cable with appropriate strain relief to prevent connector damage from machine vibration.

Maintenance suggestions: Inspect the 330103-00-04-10-02-00 quarterly for signs of physical damage, loose mounting, or cable wear. Verify the mounting torque remains at specification, as loose mounting can cause measurement errors. Check cable connections for corrosion or damage, particularly in humid environments. Clean the sensor housing with a mild detergent if contaminated, avoiding abrasive materials that could damage the surface. Perform annual calibration using a vibration calibrator to ensure measurement accuracy.
