As an automation component, the 21128-13-02 is intended for deployment in panel-based control cabinets and machine enclosures where the Bently Nevada product portfolio equipment is installed. It performs a defined automation function within the control system and is selected to match the installed Bently Nevada platform.

Specific electrical and mechanical ratings depend on the exact configuration and suffix of the part; the original datasheet should be consulted for the definitive specification.

Maintenance & Diagnostics

Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.

Sourcing & Procurement

When sourcing the 21128-13-02, distinguish three supply tiers: (1) genuine Bently Nevada stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.

Confirm mechanical and electrical compatibility with your Bently Nevada product portfolio installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Frequently Asked Questions

Specifications

Velocity Transducer Housings protect velocity sensors from damage caused by hose-directed water, corrosion, physical abuse, or other adverse environmental conditions. Constructed of 303 stainless steel, these housings are designed to meet NEMA 4X and IP65 requirements when properly installed. The 21128 housing is preferred for most non-hazardous environmental conditions. The CA21128 is the explosion-proof version that is CSA certified for use in Classes I, II, and III, Division 1, Groups B, C, D, E, F, and G. It must be ordered and shipped with a CSA approved velocity sensor installed in the assembly. The BA42608 housing is used for BASEEFAapproved installations where compliance with BS EN 60079 14 is necessary. It provides the environmental and physical protection needed to comply with the IP65 rating defined in IEC standard 144. Each of these housings is now available with a tall cap. The tall cap option is required if the customer wants to install a Velomitor CT in a housing. The tall cap option is also required if installing either a 9200 or 74712 Seismoprobe with an isolated base into the 21128 housing. When using the 21128 Housing, cable part number 89477-AA is necessary to connect the Velomitor Sensor to a monitor.
