2. Product introduction

The BENTLY NEVADA 330704-00-50-10-01-CN is a high-performance velocity sensor designed for continuous vibration monitoring in industrial machinery. As part of BENTLY’s 3300 series, this sensor combines a piezoelectric accelerometer with integral signal conditioning to deliver a direct 4-20 mA output, proportional to vibration velocity (mm/s).

Engineered for reliability in harsh environments, the 330704-00-50-10-01-CN excels in applications where accurate vibration data is critical—from pumps and motors to turbines and compressors. Its stainless steel housing and IP68 rating make it suitable for use in wet, dusty, or corrosive settings, including offshore platforms and chemical plants. By converting mechanical vibration into a standard electrical signal, the 330704-00-50-10-01-CN enables seamless integration with PLCs, DCS, and condition monitoring systems, providing actionable insights into machinery health and enabling predictive maintenance strategies.

3. Core advantages and technical highlights

Wide temperature resilience: The 330704-00-50-10-01-CN operates reliably from -40°C to +120°C, outperforming standard sensors in high-heat environments. In steel mill rolling stands, where ambient temperatures exceed 100°C, it maintains stable output, unlike sensors with plastic components that degrade under thermal stress.

Submersible design: With an IP68 rating, the sensor withstands submersion up to 10 meters, making it ideal for flood-prone areas such as wastewater treatment plants or marine applications. Its 316L stainless steel housing resists corrosion from saltwater, chemicals, and industrial solvents.

Integral signal conditioning: Eliminating the need for external amplifiers, the 330704-00-50-10-01-CN processes raw acceleration data internally to output a 4-20 mA signal. This reduces wiring complexity and signal loss in long cable runs (up to 100 meters), a critical advantage in large facilities like power plants.

CNEx certification: Specifically certified for explosive environments in China, the 330704-00-50-10-01-CN meets strict safety standards for use in oil refineries, gas processing plants, and chemical facilities where flammable gases or dust are present.

4. Typical application scenarios

Water pump monitoring: In municipal water treatment plants, the 330704-00-50-10-01-CN is mounted on centrifugal pump bearings. It detects vibration increases (e.g., from 5 mm/s to 15 mm/s) caused by impeller wear or bearing degradation, sending a 4-20 mA signal to a SCADA system. Operators use this data to schedule maintenance, preventing unplanned pump failures that disrupt water supply.

Marine engine surveillance: On offshore drilling rigs, the sensor monitors diesel engine vibration. Its IP68 rating protects against saltwater spray, while its wide temperature range handles engine compartment heat. By tracking vibration trends, it identifies crankshaft imbalance or cylinder misfire, enabling timely repairs and avoiding costly downtime at sea.

Chemical reactor agitators: In chemical plants, the 330704-00-50-10-01-CN monitors agitator vibration in corrosive environments. Its 316L housing resists acid exposure, and CNEx certification ensures safe operation in explosive zones. A sudden spike in vibration (e.g., from 8 mm/s to 30 mm/s) triggers an alarm, indicating gearbox failure and preventing reactor overpressure incidents.

6. Installation, commissioning and maintenance instructions

Installation preparation: Before mounting the 330704-00-50-10-01-CN, ensure the target surface is clean and flat. Use M8 stainless steel bolts (torque to 25 Nm) to secure the sensor, ensuring a rigid connection—loose mounting causes measurement errors. Route the integral cable away from high-voltage lines to minimize EMI, and avoid sharp bends (minimum radius: 50 mm). For explosive environments, verify the installation meets local safety codes (e.g., GB 50058 in China) and use certified cable glands.

Maintenance suggestions: Inspect the 330704-00-50-10-01-CN quarterly for cable damage or corrosion—replace the sensor if the cable jacket is cracked. Annually, verify calibration using a vibration shaker: apply 25 mm/s at 100 Hz and confirm the output is 12 mA (±0.24 mA). Clean the sensor body with a soft cloth and isopropyl alcohol; avoid abrasive cleaners that damage the housing. For submersed applications, check the cable entry seal yearly—replace if signs of leakage are found.
