Product Overview
When a velocity transducer in a hazardous process area needs a secure, certified home, the 107770-02-01 from Bently Nevada delivers. This Velocity Transducer Housing carries CENELEC approval for Zone 1, Group IIC applications. It combines the 330500 Velomitor Sensor and a 21128 Housing, preinstalled at the factory.
That factory assembly saves you time on site. The unit arrives New & Original in Factory Packing, so your maintenance team can move straight to installation. For oil, gas and industrial automation teams, this is a practical, ready-to-ship spare.
Key Specifications
| Specification | Value |
|---|---|
| Model | 107770 – Velocity Transducer Housing – CENELEC approved |
| Mounting Thread | 3/4-14 NPT |
| Cable Exit Fitting | 1/2-14 NPT plug |
| Hazardous Area Rating | CENELEC Zone 1, Group IIC |
| Compliance | RoHS Directive 2011/65/EU |
| Condition | New & Original in Factory Packing |
The 3/4-14 NPT mounting thread matches common machine casing ports, so the housing seats firmly without adapters. The 1/2-14 NPT plug closes the cable exit and keeps the enclosure sealed in dirty plant environments. The CENELEC Zone 1, Group IIC rating means the housing suits areas where explosive gas atmospheres may occur during normal operation.
Safe Use in Hazardous Areas
The 107770-02-01 follows ATEX/IECEx conditions of safe use. In Zone 0/1, connect the equipment to apparatus that meets the listed entity parameters. Cables of type A or B, in compliance with EN 60079-25, must respect the cable parameters listed with the entity parameters. In Zone 2, the supply electrical parameters shall not exceed the values in the applicable tables.
Always follow the manufacturer’s safety manual for installation and inspection. Confirm entity parameters and cable types with your site engineer before commissioning.
Where It Fits
This housing supports vibration monitoring on critical rotating machinery. In oil and gas plants, it protects the Velomitor sensor on compressor and pump trains inside classified zones. In power generation, it mounts on turbine bearing housings where gas hazards exist. Industrial automation teams also use it on large motors and gearboxes that run in Zone 1 areas.
Because the sensor and housing ship as one factory-assembled unit, you avoid field-mating errors. That keeps your monitoring loop reliable from day one.
Maintenance and Reliability
Inspect the housing periodically for mechanical damage and check that the cable exit plug stays tight. Keep the mounting thread clean so the unit seats correctly during reinstallation. In hazardous areas, never open the assembly while the circuit is energized. Follow your plant’s safety procedures and the manufacturer’s manual at all times.
Integration Note
Wiring into your existing monitoring network may require an external gateway or connection module. Confirm cables, glands and gateways with your supplier before you order. Bently Nevada monitoring systems pair with this housing, but always verify compatibility with your specific rack and sensor loop.
Selection Checklist
Before buying, confirm the mounting thread matches your machine port, the cable exit fitting suits your cable gland, and the area classification matches Zone 1, Group IIC. Also check that your supply and entity parameters align with the ATEX/IECEx conditions of safe use.
