Bently Nevada 3701/46 ADAPT Hydro Monitor
A compact configurable protection and condition-monitoring platform for hydroelectric generating machinery.
Product Profile
3701/46 identifies the ADAPT Hydro Monitor family. It combines machinery protection, condition monitoring and application-specific hydro signal processing in a distributed package located near the monitored unit.
The family reference is not a complete order string. Redundancy, input modules, output module and approval fields must be selected from the installed channel and protection design.

System Role
- Performs A/D conversion, digital signal processing, alarms, relay logic and communications within the monitor.
- Supports hydro-focused measurements for vibration, position, speed and dynamic-pressure applications.
- Publishes data to configuration, condition-monitoring and plant-automation systems.
- Allows a modular combination of processor, sensor-input and relay-output hardware.
Compatibility
- Develop the order code from the complete sensor list and required channel types.
- Confirm simplex architecture and power redundancy against the plant protection philosophy.
- Match network protocols, controller mappings and System 1 or BNMC integration.
- Select approvals from the actual installation classification and country requirements.
Applications
- Hydroelectric turbine-generator vibration and position monitoring.
- Dynamic-pressure observation for hydraulic operating conditions.
- Gearbox, speed-reference and auxiliary-machine protection around a hydro unit.
FAQ
Is 3701/46 a complete orderable model?
No. The family code must be completed with redundancy, input-module, output-module and approval selections.
Which sensor list is needed to configure 3701/46?
Provide every proximity probe, accelerometer, velocity sensor, speed reference and dynamic-pressure sensor with its measurement and alarm purpose.
Can a 3701/40 project be loaded directly into 3701/46?
Do not assume direct project interchangeability; the hydro monitor has application-specific channel and measurement capabilities that require engineering review.
What network information should accompany a 3701/46 enquiry?
Include both port roles, IP settings, Modbus or EGD mapping, System 1 connection and BNMC project version.
How should redundancy be selected for 3701/46?
Base the choice on the protection philosophy, availability requirement, power architecture and complete plant risk assessment.
What acceptance tests follow a 3701/46 installation?
Validate each channel, speed reference, alarm, relay, network path, power input and the full hydro-unit protection logic before service release.
