Description
3500 Internal Barriers are intrinsically safe interfaces that provide explosion protection for transducer systems connected directly to the 3500 Machinery Protection System.
The internal barriers are fully compatible with the 3500 System and provide a convenient and cost-effective solution for installing all types of transducer systems within a hazardous area.
Unlike external barriers, 3500 Internal Barriers are an integral part of the 3500 System and will not degrade the system's performance.
We offer Bently Nevada transducer systems with comprehensive approvals for hazardous area installations.
The transducer systems are matched to those of the 3500 Internal Barriers. See Compatible Monitors and Transducers on page 6.
Each component complies both individually and as part of a system with the safety requirements of North American and international standards. Hence, you don't have to reference individual certificates to verify the compatibility between components.
Standard and internal barrier monitors can reside within the same 3500 rack. You can upgrade standard monitors by replacing existing I/O modules with those that contain internal barriers.
Ordering Information
For the detailed listing of country and product specific approvals, refer to the Approvals Quick Reference Guide (108M1756) available from Bently.com.
3500/04-01 IS Earthing Module
When ordering internal barriers, specify the appropriate I/O module type for each monitor module.
Install an IS Earthing Module in each rack containing internal barriers.
Refer to each monitor module's datasheet for specifications and ordering information.
