Product Description
The Bently Nevada 79530-01 / 81410-01 is a high-reliability vibration monitor designed for the 3300 Machinery Protection System. It provides continuous monitoring of casing vibration on critical rotating machinery, including pumps, motors, and fans.
This module converts mechanical vibration into electrical signals and compares them against Alert and Danger setpoints. It interfaces with velocity transducers (e.g., Seismoprobe 9200 or 74712) to provide accurate velocity measurements in mm/s or inches/s. The front monitor (79530-01) and rear I/O module (81410-01) together enable dual-level alarms, buffered diagnostic outputs, and proportional 4-20 mA signals for integration with DCS or SCADA systems.

Key Features
-
Effective Casing Monitoring: Accurately captures internal mechanical forces in machines with high rotor-to-casing mass ratios.
-
Dual-Channel Capability: Supports two independent channels for drive-end and non-drive-end bearings.
-
Self-Diagnostic "OK" Circuit: Continuously verifies transducer and wiring health; inhibits false alarms if a fault is detected.
-
Legacy Reliability: Fully compatible with 3300 racks, providing decades of dependable operation without system upgrades.
Frequently Asked Questions
Can this module be used with accelerometers?
No, the 81410-01 is optimized for velocity transducers. Accelerometer inputs require a 3300/25 or 3300/26 series monitor.
What is the difference between the 81410-01 and 81410-02?
The suffix denotes optional configurations such as internal barriers or recorder output scaling. The -01 is the standard non-barrier version.
