Applications & Use Cases

In oil and gas refineries, the 107770-01-01 monitors rotating machinery such as pumps and compressors in Zone 1 areas. Chemical plants benefit from its Group IIC rating, covering hydrogen and acetylene atmospheres. Power generation facilities also rely on this housing for turbine vibration sensing in hazardous zones.

Installation & Setup

Mount the housing using the unthreaded option, securing it with appropriate brackets. Connect the cable via the 1/2-14 NPT plug, ensuring a sealed conduit run. For Zone 0/1 installations, pair with equipment meeting the entity parameters listed in the datasheet. Always follow Bently Nevada's wiring guidelines for intrinsic safety.

Maintenance & Reliability

Periodically inspect the housing for corrosion or damage, especially in harsh chemical environments. Verify that cable glands remain tight to maintain hazardous area integrity. The preassembled design minimizes internal connection failures, supporting long-term reliability.

Compatibility & Integration

This housing integrates with Bently Nevada monitoring systems that accept Velomitor sensor inputs. It is designed for use with intrinsically safe barriers and isolators that meet the specified entity parameters. For Zone 2 applications, ensure supply parameters do not exceed table values.
