Four-Channel Proximitor / Seismic Monitor for four-channel proximity, velocity or acceleration monitoring, with the exact part number, rack configuration and hardware compatibility checked before supply.
The Bently Nevada 3500/42M 140734-02 is a Four-Channel Proximitor / Seismic Monitor used for four-channel proximity, velocity or acceleration monitoring. It is commonly applied in radial vibration monitoring and thrust position and differential expansion.
Selection must follow the complete part number and installed-system configuration. Before ordering, confirm transducer and channel type, rear i/o termination style, rack configuration and alarm logic.
COMMON APPLICATIONS
Tell us the controller, communication network and installed panel details. That context helps prevent a visually similar but incompatible replacement.
BENTLY NEVADA MODEL CODE
Read the complete ordering code from left to right. Every group matters when matching an installed system or preparing a spare.
VERIFIED MODEL DATA
Technical values are compiled from official Bently Nevada product documentation for this exact article number. Always check the delivered unit nameplate and revision before installation.
Availability, condition, revision and exact installed-system compatibility are confirmed in writing before supply.
BUYER QUESTIONS
It is a Four-Channel Proximitor / Seismic Monitor used for four-channel proximity, velocity or acceleration monitoring.
Confirm the full part number, then verify transducer and channel type, rear i/o termination style, rack configuration and alarm logic.
Do not select by appearance alone. The monitor family, companion module or transducer, rack configuration, signal type and hardware revision must match the installed system.
Send the complete part number, quantity, required condition, destination and clear nameplate or rack-BOM photos.
FRONT AND REAR CARD COMBINATIONS
Use the complete ordering code to match the required rear I/O interface and certification. The front-card part number identifies the monitor or control module; the rear-card part number identifies the I/O, termination and signal arrangement.
