Description

The Bently Nevada TEK/5110N, also cataloged as the TEK/5110N Modified Single Beam Oscilloscope, operates as a dedicated hardware component for conditioning and displaying dynamic radial vibration data within machinery diagnostic networks. Originally engineered by Tektronix as the 5110 and custom-modified under specification MOD 709V for Bently Nevada, this three-bay instrument provides direct physical and vector execution for orbit analysis.

Hardware Specifications

Machinery Monitoring and Diagnostic Attributes

The instrument incorporates an internal X-Y switching board that specifically forces the display into an orbit layout using Left Vertical versus Right Vertical amplifier signals. During active mechanical tracking, this routing mechanism executes precise cross-talk suppression and isolates dynamic rotor dynamics without relying on standard internal sweep triggers. When operators connect proximity probes, the customized timebase plug-in (5B10N MOD 709V) utilizes an explicit “L vs R” position, which automatically confirms orbital tracking and simplifies gap voltage verification across orthogonal measurement planes.

Frequently Asked Questions

Q: How does the MOD 709V modification alter the physical interface of the 5B10N timebase plugin?

A: The modification deletes the variable time/division control and replaces the standard BNC external input connector with a rugged green front-panel binding post. Additionally, turning the main selector fully counter-clockwise to the “L vs R” mark engages an internal hardware switching relay to route the left and right channel vectors.

Q: What specific hardware change protects the display screen when observing high-voltage dynamic transients?

A: The modified mainframe features an integrated, specialized implosion shield mounted directly over the 8×10 division CRT screen alongside a yellow front-panel binding post designed for AC-coupled external intensity inputs.

Field Installation Guidelines

First, slide the mainframe chassis into a standard 19-inch electronic equipment rack or position it securely on a level technical workbench. Next, verify that the ventilation cutouts on the sides and rear retain at least 75 mm of clearance to ensure continuous airflow across the low-voltage power supply heat sinks. Installers must then set the rear-panel line selector switch to match the local mains voltage supply (115 Vac or 230 Vac) before inserting the power cord. Finally, route all dynamic signals from the Proximitor sensors using 50-Ohm coaxial cabling, and terminate the outer shield braid directly to the yellow or green structural chassis binding posts to eliminate environmental noise injection into the dynamic orbit loops.
