Description

The 330525-00 is a 330525 Velomitor XA Piezo-velocity Sensor configured with Option 00, indicating no required agency approvals. This sensor is a ruggedized version of the standard Bently Nevada 330500 Velomitor, designed for industrial machinery vibration monitoring where environmental resilience is critical. Its construction features a 316L stainless steel case, providing superior corrosion resistance and durability in harsh operating conditions. This sensor is engineered for mounting without an additional protective housing. When paired with a compatible mating extension cable, the design meets IP-65 and NEMA 4X requirements, ensuring protection against moisture and debris. The device provides a continuous velocity signal, making it a reliable choice for monitoring machine casing vibration on a wide range of rotating equipment.

Features

316L stainless steel case for durability and corrosion resistance
Designed for direct mounting without external housings
Compatible with IP-65 and NEMA 4X protection ratings when installed with mating extension cable
Frequency response of 4.5 to 2,000 Hz (270 to 120,000 cpm)
Sensitivity of 3.94 mV/mm/s (100 mV/in/s) nominal
Hermetically sealed 2-pin Mil-C-26482 connector
Operating temperature range from -55 degC to +121 degC

Applications

The Velomitor XA sensor is widely used in heavy industrial sectors such as power generation, oil and gas, and petrochemical processing. Typical applications include:

Monitoring casing vibration on rotating machinery
Critical machinery protection where environmental sealing is required
Applications requiring durable, non-contact sensing in moist or exposed environments

Installation Guidelines

Proper installation is essential to maintain the accuracy of housing measurements. Ensure the mounting location provides a direct, rigid path for machine vibration. Avoid installations that might introduce non-representative signals. This sensor requires a mating extension cable (such as 106765 series) to achieve its specified IP-65 and NEMA 4X environmental protection. Tighten the sensor to the specified torque of 45 N-m to prevent signal degradation or resonance issues.

Compliance and Certifications

This specific configuration (Option 00) does not include hazardous area approvals. For installations requiring CSA, ATEX, or IECEx certifications, select the appropriate agency approval option during the ordering process. The base design is compliant with standard CE requirements.
