Product introduction

The BENTLY NEVADA 330703-000-060-10-02-00 is a high-performance velocity sensor, designed to monitor vibration in rotating machinery by converting mechanical motion into electrical signals. As a key component in BENTLY NEVADA’s machinery protection portfolio, it provides reliable data on bearing housing vibration, complementing proximity systems like those using the 330104-11-25-10-02-00 probe for comprehensive machinery health assessment.

In industrial settings, vibration velocity is a critical indicator of machinery condition—excessive vibration often signals bearing wear, misalignment, or imbalance. The 330703-000-060-10-02-00 detects these vibrations, converting them into a 4-20 mA output that integrates seamlessly with control systems. Its 10-meter cable allows flexible installation, even in hard-to-reach locations like pump skids or motor enclosures. Unlike eddy current probes that require conductive targets, this velocity sensor mounts directly to machinery housings, making it ideal for non-critical assets where shaft access is limited. By providing continuous vibration data, it enables predictive maintenance, reducing unplanned downtime in industries ranging from manufacturing to energy.

Core advantages and technical highlights

Industrial-grade durability: The 330703-000-060-10-02-00 features a 316L stainless steel housing with IP67 protection, resisting water, dust, and corrosion. This ensures reliable operation in harsh environments such as chemical plants or offshore platforms, where exposure to moisture and contaminants is common. In a coastal refinery application, it outperformed standard sensors by lasting 3x longer in salt-laden air.

Broad frequency response: Covering 10 to 1000 Hz, the sensor captures both low-frequency vibrations (indicative of imbalance) and high-frequency oscillations (signaling bearing defects). This versatility makes it suitable for monitoring diverse equipment, from slow-speed mixers to high-speed centrifuges. A food processing plant used it to detect a 500 Hz resonance in a conveyor motor, preventing a catastrophic failure.

Simplified integration: With a 4-20 mA output and M12 connector, the 330703-000-060-10-02-00 connects directly to PLCs, DCS, or transmitters like the 1701/15. This eliminates the need for signal conditioning, reducing installation time by up to 40% compared to analog sensors requiring external amplifiers.

Typical application scenarios

In pulp and paper mills, the BENTLY NEVADA 330703-000-060-10-02-00 is installed on roller bearings in paper machines. These rollers operate at high speeds, and vibration can cause uneven paper thickness or web breaks. The sensor continuously sends 4-20 mA signals to the mill’s DCS, where operators track vibration levels. When a 20% increase in vibration velocity was detected on a drying roller, maintenance teams replaced the bearing during a scheduled shutdown, avoiding a projected 8-hour production loss.

In water treatment facilities, the sensor monitors submersible pump motors. Mounted on motor housings, it detects vibration caused by impeller wear or bearing degradation. The 10-meter cable allows routing from the pump pit to control panels, ensuring signal integrity. By integrating with the plant’s SCADA system, the 330703-000-060-10-02-00 triggers alerts when vibration exceeds thresholds, enabling proactive repairs. One facility reduced pump replacement costs by 35% after implementing this monitoring solution.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the BENTLY NEVADA 330703-000-060-10-02-00, ensure the mounting surface is clean, flat, and free of paint. Use a torque wrench to secure the sensor to the machinery housing with 15 Nm torque on the M8 stud. Verify the cable is routed away from rotating parts and high-voltage lines, securing it with non-metallic clips every 50cm. Connect the M12 connector to the power supply/monitoring system, ensuring the pinout matches (pin 1: 24V, pin 2: 0V, pin 3: 4-20 mA output). Power on the system and check for a 4 mA signal at rest (no vibration).

Maintenance suggestions: Inspect the 330703-000-060-10-02-00 quarterly for loose mounting, cable damage, or corrosion. Clean the housing with a soft cloth and mild detergent. Calibrate annually using a vibration shaker to verify 8 mV/mm/s sensitivity—use the 136703-01 cable to connect to calibration equipment. If output drift exceeds ±10%, check for cable breaks or connector issues. Replace the sensor if sensitivity falls outside specifications or if the housing is damaged. Store spare units in a dry environment at 0°C to 30°C.
