Bently Nevada Vibration Monitoring Parts Supplier
G-SAT International sources genuine Bently Nevada machinery protection and vibration monitoring parts — 3500 Series, legacy 3300 Series, and proximity probe transducer systems. We are an independent supplier, not an authorised Bently Nevada or Baker Hughes distributor.
The Company That Invented Vibration Monitoring
Founded in 1961 by Don Bently, working from his own garage in Nevada, Bently Nevada created the proximity probe technology that became the industry standard.
Bently Nevada was founded in 1961 by Don Bently in Carson Valley, Nevada. Bently's development of the eddy current proximity probe became the first commercially successful transducer of its kind — and was ultimately adopted by the American Petroleum Institute (API) as the standard device for measuring shaft vibration during acceptance testing of centrifugal compressors, a standard still referenced across the industry today.
The company grew its monitoring system product line through the 1970s-1990s (including the 1700, 3300, 5000 and 9000 series), before Don Bently sold the company to GE Energy in 2002 at $250 million in annual sales. Following GE's 2017 merger with Baker Hughes, Bently Nevada operates today as a Baker Hughes business, with over 1,400 employees, facilities in nine countries, and more than four million sensors installed worldwide across oil & gas, power generation, petrochemical and other critical-machinery industries.
Bently Nevada Product Families
We source genuine parts across Bently Nevada's monitoring system generations, current and legacy.
3500 Series
System racks (3500/05), power supplies (3500/15), rack interface modules (3500/20), Keyphasor modules (3500/25), Proximitor/Seismic monitors (3500/40M, 3500/42M), temperature monitors (3500/65) and communication gateways (3500/91, 3500/92).
3300 Series (Legacy)
Including the 3300 XL Series — precise shaft vibration and displacement measurement systems, predecessor to the 3500 Series and still running in many plants today.
Proximity Probes & Transducers
The core sensing technology Bently Nevada pioneered — proximity probes, velocity and acceleration transducers for continuous machine vibration monitoring.
Legacy Monitoring Systems
Older-generation monitoring system parts for plants that haven't yet migrated to the 3500 Series platform.
Legacy 3300 Series & Discontinued Monitoring Hardware
The 3500 Series isn't backward compatible with the older 3300 Series — plants running legacy racks need a different sourcing path entirely.
3300 Series specialists
Still running legacy 3300 hardware? We source replacement modules and probes through our global supplier network.
Genuine, tested parts
Every module is checked before dispatch — critical given its role in protecting rotating machinery from catastrophic failure.
Fast turnaround on urgent cases
A failed monitoring channel on critical machinery can force a shutdown — we prioritise quick sourcing and dispatch.
Send Us the Part Number
Whether it's a current 3500 Series component or a legacy 3300 Series module, our sourcing desk can confirm availability and lead time.
Pricing depends on the exact model, condition and current availability. Send us the part number or a photo of the module and we'll respond with a quote — typically within one business day.
Frequently asked questions — Bently Nevada parts
Is G-SAT International an authorised Bently Nevada or Baker Hughes distributor?
No. G-SAT International is an independent global supplier and sourcing partner for Bently Nevada machinery protection and vibration monitoring parts — not an authorised Bently Nevada, GE or Baker Hughes dealer, distributor or representative. We source genuine, tested parts from the open market and our global supplier network. Bently Nevada and all related trademarks remain the property of Baker Hughes.
What is the Bently Nevada 3500 Series?
The 3500 Series is Bently Nevada's flagship rack-based machinery protection system, providing continuous online vibration, position and temperature monitoring for critical rotating equipment such as turbines, compressors and motors. It succeeded the earlier 3300 Series and is not backward compatible with it.
Do you supply legacy 3300 Series or older Bently Nevada monitoring parts?
Yes. Sourcing legacy 3300 Series proximity probe systems and older Bently Nevada monitoring hardware is one of our specialities, since many plants still run this equipment alongside or instead of the newer 3500 Series.
What industries use Bently Nevada monitoring systems?
Bently Nevada systems are widely used in oil & gas, power generation, petrochemical, and other industries running critical rotating machinery such as turbines, compressors, gearboxes and large motors.
