The Bently Nevada Difference

Our founder Don Bently – entrepreneur, engineer and authority on vibration monitoring – built the Bently Nevada product line for machine condition monitoring using special condition monitoring sensor technology. For nearly seven decades, his condition monitoring systems have monitored the machine health of our customers’ mission-critical equipment such as control systems, compressors, exchangers, gearboxes, turbines, and electric motors.

Our condition-based maintenance range of sensors began with the emergence of eddy current proximity transducers and evolved into a range of condition-monitoring systems, which features proximity probes, Proximitor† sensors, eddy current proximity transducers for measuring rotor shaft position and vibration, and more.

Today, our diagnostics sensors maintain the standard of excellence set by Don, with an array of options including industrial sensor accessories and components to help reduce maintenance costs and prevent unplanned downtime and machine failure.

Why Vibration Monitoring Matters

The vibration monitoring of a machine provides data analysis of machine health. Vibration data and vibration analysis can detect the root cause of equipment failure before it results in unplanned downtime and increased maintenance costs.

This blog focuses on:

  • Basics of vibration analysis
  • Transducer types
  • How to choose the best data collector

Condition Monitoring Sensors Overview
Proximity Sensors

Our proximity sensors are ideal for measuring rotor shaft position and vibration within the clearances of its fluid film bearings and deliver superior performance in harsh environments across a wide range of applications. The sensor technology family includes proximity probes, sensors and transducer systems (to detect the presence of acceleration, velocity and pressure) to monitor your system and minimize untimed shutdowns.

Bently Nevada industrial sensors will help reduce costs in all areas of your plantwide program - insurance, maintenance, unscheduled repairs. The sensor system can boost revenue through increased uptime and production quality.

Pressure Sensors

We offer pressure sensors for many different applications. From hydro turbine and centrifugal pumps to reciprocating compressor cylinders, we have a sensor for your machine. Our pressure sensors can detect both static and dynamic pressure, come with a long operational lifetime (over 50 million cycles), can operate in high humidity environments.

The Bently Nevada line of industrial pressure sensors have many different applications, from hydro turbine and centrifugal pumps to reciprocating compressor cylinders. All work and operate easily in high humidity and harsh chemical environments.

Acceleration & Velocity Sensors

The evolution of our current velocity sensor and accelerometer line began with sensors that offered a self-generating moving-coil design used by geologists to measure movement in the earth’s crust. Today we still refer to “seismic” sensors in a nod to their origin. Today’s integrated accelerometers deploy signal processing circuitry for output signals using velocity rather than acceleration. Our experience and expertise developed over decades offers a selection of first-rate casing-mounted accelerometers and velocity sensors with a variety of models for specific applications.

Wireless Vibration Sensors

Our efficient and rugged Ranger† Pro wireless vibration sensor provides condition monitoring across a broad range of machinery in power generation, oil & gas, mining, pulp & paper, water & wastewater and other industries. This compact yet powerful wireless condition monitoring sensor greatly improves your ability to remotely monitor hard-to-reach and unsafe locations. An impressive battery life (up to five years in some configurations) also means increased protection for all of your machinery.  While the Ranger Pro is compatible with many third-party software solutions, it is now fully integrated with Bently Nevada's flagship software: System 1 machine condition monitoring software which allows for seamless, real-time, and fully customizable data.

Hydro Sensors

When you need to know what’s going on with your hydroelectric generator – especially while it’s in operation – Bently Nevada has you covered with our family of proven hydro sensors. Our hydro sensors record multiple variables – not just one – so that you can obtain a more accurate understanding of your machinery’s vibration issues. And with increased data and understanding comes the ability to more accurately diagnose a problem, and react accordingly avoiding costly downtime, misdiagnoses, and in some cases avoiding costly tear-down inspections that weren’t needed.


Bently Nevada’s industry-leading thrust and vibration transmitters, simply put, protect your critical machinery. Bently Nevada offers two types of transmitters: the 990 Vibration Transmitter and the 991 Thrust Transmitter. These compact yet durable transmitters allow you the ability to install them in small spaces with minimal clearance – where other transmitters won’t fit. In addition to our transmitters, we also provide the self-contained 177230 Piezo Accelerometer, which guarantees comprehensive condition monitoring of your general-purpose machinery.

Sensor Housings and Accessories

Our current portfolio of industrial sensor accessories offers a range of options from protective sensor housings, junction boxes, and sensor mounting brackets to wiring, flexible conduits, and conduit fittings. We also offer a selection of cables, cable protectors, and more.

Bently Nevada industrial sensors and other products work best when they are protected with the right housing. We have a variety of housing options (proximity sensor housings and velocity/acceleration sensor housings) as well as transducer cables and instrumentation wiring for all your accessory needs.

We even offer a range of test kits for system calibration requirements as well as kits for machinery simulations for research and development.

Are You Getting All The Data You Can?
Your critical machinery should be monitored using multiple condition monitoring techniques.

In some applications, a simple vibration analysis condition monitoring sensor may be all that you need. But with today’s production demands and the complexity of emerging technology – never mind the increased threats to your bottom line in the form of unplanned downtime and breakdowns – to attain a truly proactive maintenance strategy, you need all the data analysis and data collection your maintenance program can get. In short, the more condition monitoring techniques and condition monitoring sensors monitoring machine health, the better.
