Product Overview
When industrial operations require reliable vibration monitoring in hazardous environments, the Bently Nevada 107770-02-01 Velocity Transducer Housing delivers a robust solution. This CENELEC approved housing integrates a 330500 Velomitor Sensor with a 21128 Housing, preinstalled at the factory for immediate deployment. Designed for CENELEC Zone 1, Group IIC hazardous area applications, this unit ensures accurate velocity measurements in explosive atmospheres. SpareTechPLC supplies this model as new and original in factory packing, backed by a 12-month warranty.
Technical Specifications
The 107770-02-01 features specific mounting and cable exit options tailored for industrial installations. The mounting thread option is 3/4-14 NPT, providing a secure fit in standard industrial ports. The cable exit fitting option uses a 1/2-14 NPT plug, simplifying wiring in confined spaces. This version complies with ATEX and IECEx standards for Zone 0/1 and Zone 2 hazardous areas, with entity parameters governing safe electrical connections. The unit meets RoHS Directive 2011/65/EU, ensuring environmental compliance.
Industry Applications
In petrochemical plants, the 107770-02-01 monitors rotating machinery like pumps and compressors in Zone 1 areas. Its CENELEC approval allows installation where flammable gases are present, providing early warning of bearing wear or imbalance. In gas processing facilities, the housing protects the sensor from harsh conditions while delivering precise velocity data for predictive maintenance programs. This model replaces older transducer housings that lack hazardous area certifications, reducing compliance risks.
Installation & Setup Guidance
Mount the 107770-02-01 using the 3/4-14 NPT thread into a compatible port on the machinery casing. Ensure the mounting surface is clean and free of debris to maintain a proper seal. Connect the cable through the 1/2-14 NPT plug, using cable type A or B per EN 60079-25 to respect entity parameters. For Zone 0/1 installations, verify that the connected equipment meets the listed entity parameters. For Zone 2, confirm supply electrical parameters do not exceed the values in the provided tables.
Maintenance & Reliability
Periodically inspect the housing for signs of corrosion or damage, especially in corrosive environments. Verify that the cable exit fitting remains tight to maintain the hazardous area seal. The preinstalled sensor-housing combination reduces field assembly errors, improving long-term reliability. Regular calibration checks of the Velomitor sensor ensure measurement accuracy, extending the service life of the monitoring system.
Compatibility & Integration
The 107770-02-01 integrates with Bently Nevada monitoring systems that accept velocity transducer inputs. It replaces the need for separate sensor and housing purchases, simplifying logistics. The CENELEC approval ensures compatibility with safety instrumented systems in hazardous areas. For new installations, pair this housing with compatible Bently Nevada cables and junction boxes to maintain entity parameter compliance.
Selection Guide & Purchasing Advice
Before ordering, verify that your application requires the 3/4-14 NPT mounting thread and 1/2-14 NPT cable exit. Confirm the hazardous area classification matches CENELEC Zone 1, Group IIC. SpareTechPLC offers this model as new and original, ensuring reliable performance. Contact our team for current lifecycle status and availability if you need to replace an existing unit.
