Description

Bently Nevada 330500-02-00 Product Introduction
Model: 330500-02-00
Product Name: Velomitor Piezo-Velocity Sensor
Weight: Approximately 0.15 kg
Origin: United States

HS Code: 90318090 (vibration measuring transducer for industrial monitoring)
Operating Temperature: Continuous operating range -40 °C to +121 °C; storage temperature -55 °C to +135 °C
Input: 18-30 V DC constant-current power supply input from monitoring instrument side; mechanical vibration input transferred from machine casing and bearing housing surfaces.
Output: Analog AC velocity signal output with nominal sensitivity 3.94 mV/mm/s (100 mV/in/s); frequency response covers 4.5 Hz to 5 kHz; signal transmitted via 2-pin hermetically sealed MIL-C-5015 connector, maximum allowable cable length reaches 305 meters without obvious signal attenuation.
Dimensions: Diameter 25.3 mm, overall length 66 mm, mounting thread M8×1, surface-mount design for direct installation on equipment housing.
Main Functions: Converts mechanical casing vibration into proportional electrical velocity signals by means of piezoelectric sensing element and built-in integrating circuit. It performs absolute vibration measurement relative to free-space reference, capturing radial and axial vibration of bearing housings to reflect unbalance, misalignment, bearing wear and looseness faults of rotating equipment. Without moving mechanical parts inside, it avoids performance degradation caused by friction and wear, and allows arbitrary installation orientation including horizontal, vertical and tilted mounting. It delivers stable vibration data for upper-level monitoring and protection instruments such as 3500 series and 1900/65M, supporting real-time vibration trending, threshold alarming and machinery protection trip logic. The hermetically sealed stainless-steel housing provides resistance against moisture, dust and corrosive gas. It supports long-distance field wiring, maintains signal integrity over long cable runs. It complies with hazardous-area certification standards, enabling safe deployment inside explosive-risk plant areas. Collected vibration data serves as core basis for predictive maintenance, assisting operation staff to identify early-stage mechanical defects and prevent unplanned equipment shutdown.
