The Bently Nevada 3300/70 Dual Valve Position Indicator is a specialized rack-mounted module within the 3300 Series monitoring system. It is engineered to provide precise, continuous monitoring of valve positions in large rotating machinery, such as steam and gas turbines. The module features two independent measurement channels, allowing for redundant or dual-point tracking of valve movement to support machinery protection through integrated alarm and trip logic.
Features
Dual independent channels for valve position measurement.
Proportional analog outputs (4 to 20 mA and 1 to 5 VDC) for external integration.
Integrated relay outputs for Alert and Danger alarm conditions.
Front-panel LED status indicators for OK, Bypass, Alert, and Danger states.
Designed for seamless integration into standard Bently Nevada 3300 series rack systems.
Applications
Steam turbine valve position monitoring.
Gas turbine valve tracking.
Critical machinery protection systems requiring valve position feedback.
Large rotating equipment where valve travel accuracy is essential for operational safety.

Installation Guidelines
Ensure the 3300 rack is powered down before inserting or removing the module to prevent electrical damage.
Verify that the module is fully seated in the rack slot to ensure proper backplane connection.
Use shielded cabling for all transducer inputs to minimize electromagnetic interference (EMI) in industrial environments.
Maintain proper ventilation within the cabinet to ensure the module operates within its specified temperature range (0 to 60 degC).
Follow standard ESD (Electrostatic Discharge) handling procedures when touching the module circuitry.
FAQ
What does the XX in the model number represent?
The XX suffix denotes the specific measurement range and transducer compatibility configuration required for your specific valve application. Please verify your system requirements before ordering.
Is this module compatible with other Bently Nevada series?
No, this module is specifically designed for the 3300 Series rack system and is not directly compatible with 3500 or other series hardware.
