Bently Nevada 16925-30 | Seismic Transmitter

Product Overview

The 16925-30 operates as a seismic transmitter within the Bently Nevada monitoring lineup. This unit converts velocity signals from seismic transducers into proportional 4–20 mA outputs. Consequently, plant operators gain continuous vibration monitoring for cooling towers, fans, and balance-of-plant machinery.

Construction and Materials

The housing uses aluminum, which shields internal electronics from electromagnetic noise. Meanwhile, screw terminals accept standard field wiring without specialized tools. The compact enclosure fits existing cabinets, so retrofits require minimal downtime.

Interface and System Compatibility

This transmitter accepts signals from Bently Nevada seismic transducers. Additionally, the 4–20 mA output interfaces directly with PLCs and DCS platforms. Therefore, users integrate vibration data into existing control systems easily.

Installation Guidelines

Mount the unit away from excessive heat and strong electromagnetic sources. Furthermore, route input and output wiring separately to reduce noise coupling. Correct grounding practice improves measurement stability, so follow plant standards carefully.
