Bently Nevada 330500-07-00 Velocity Sensor

Bently Nevada 330500-07-00 Velomitor Piezo-velocity Sensor

Product Introduction

The Bently Nevada 330500-07-00 delivers high-performance vibration monitoring for critical rotating machinery. This Velomitor Piezo-velocity Sensor translates physical motion into a precise electrical signal. Its rugged construction guarantees reliable operation in the harshest industrial environments. Maintenance teams rely on this sensor for accurate data acquisition in predictive maintenance programs.

Core Technical Parameters

The 330500-07-00 offers a standard sensitivity of 3.94 mV/mm/s with a tolerance of ±5%. This model provides a broad frequency response from 4.5 Hz to 5 kHz at ±3.0 dB. For more demanding measurements, it achieves a tighter tolerance of ±0.9 dB from 6.0 Hz to 2.5 kHz. Furthermore, the amplitude linearity maintains within ±2% up to 152 mm/s peak. Its output bias voltage is -12 ±3.0 VDC over the entire temperature range. The dynamic output impedance is less than 2400 Ω, ensuring strong signal transmission.

Operating Limits and Environmental Resilience

This sensor operates flawlessly across an extreme temperature range from -55°C to 121°C. It also survives shock events as high as 5,000 g peak. The hermetically-sealed case allows operation in 100% relative humidity, provided it is not submerged. Additionally, the sensor features a case-isolated design, which prevents ground loop interference. The base strain sensitivity of 0.005 in/s/mstrain minimizes measurement errors due to mounting surface deformation. The Bently Nevada 330500 also exhibits very low magnetic field susceptibility, ensuring accuracy near motors.

Installation Specifications and Physical Properties

This model features the "-07" mounting thread option, specifying a 3/8-16 UNC thread. Apply a mounting torque between 32-46 kg cm (24-40 in-lb) for a secure installation. Pay attention to polarity during setup: motion toward the connector makes Pin A positive relative to Pin B. This Velomitor sensor weighs only 142 grams and has a compact diameter of 25.3 mm. Its height measures 63.2 mm, making it suitable for tight installation spaces. For optimal signal quality, use a cable length up to 208 feet (63m) under typical conditions.

Certifications and Industry Compliance

The Bently Nevada 330500-07-00 carries essential certifications for global deployment. It meets the requirements for hazardous areas, including Ex ia IIC T4 and AEx ia IIC T4. Furthermore, it is suitable for Class I, Division 1, Groups A, B, C, and D classifications. This sensor also complies with the EMC Directive 2014/30/EU and the RoHS Directive 2011/65/EU. Moreover, it holds DNV approvals for both ships and offshore structures. These comprehensive approvals make this sensor a versatile choice for various industries.
