Dynapar onsite CMs delivers feature-rich performance

Gurnee, IL-based Dynapar says its On- Site™ condition monitoring system (CMS) is designed to deploy in minutes. The four-sensor device combines affordable, remote 24/7 condition monitoring with cloud-based analytic software for multi-stakeholder access.

It says that previous such systems have been too expensive, complex or time-consuming to install on any but the most high-value pieces of equipment. Dynapar developed the OnSite System specifically to address these limitations and provide its customers with a practical solution “to monitor their critical assets, their bad actors, and their hard-to-reach equipment” at an affordable price.

The OnSite system features four sensors that each measure vibration along three axes, plus temperature. It can also connect to an encoder, integrating speed to enhance analytics and troubleshooting. The wireless OnSite System can monitor virtually any asset of interest, not just high-value ones like turbines. After all, not every asset is a turbine. Even a simple cooling fan can be a critical asset if its failure also takes down an entire production line.

Because the hub is designed for rapid installation, it is just as effective to deploy temporarily to monitor a troubled asset in the run-up to a scheduled maintenance shutdown as it is to install permanently. In just minutes, any stakeholder in the organization, or thirdparty service provider can be analyzing real-time data from the equipment from any location be it across the plant or across the world. They simply log into the password-protected web app using their computer, tablet or smart phone. If an asset exhibits abnormal behavior, users receive e-mail alerts through a customizable alarm function, catching problems before they lead to downtime.

The OnSite Analytics web app is designed to be sophisticated enough to support the needs of licensed vibration technicians but easy enough for use by a novice machine operator. Its capabilities range from simple configurable dashboards and alarms to advanced diagnostic tools like FFTs and waterfall plots. Through existing wireless or cellular networks, the system incorporates robust security and operates with existing firewalls, making it appealing to IT departments.

Dynapar says that the OnSite system is already established in installations in paper processing, converting, steel manufacturing and more.

OnSite sensor hub. A central hub aggregates data from four separate wired sensors. Each sensor incorporates a triaxial accelerometer and a temperature sensor which enable it to collect integrated vibration and temperature data, plus speed/position data (with optional encoder input). A built-in wireless interface enables the hub to connect to existing Wi-Fi networks. Alternatively, it can connect to cellular networks via an optional router. The hub then sends the data to the cloud using a secure REST API. This eliminates the need to link the unit to the plant’s control system.

OnSite features include:

• Vibration frequency range: 0- 1000Hz with low-pass anti-aliasing and digital filter
• F-max: 2000 Hz
• Frequency accuracy: +/- 1 Hz
• Measurement range (acceleration): +/- 8g programmable
• Programmable high-pass filters
• Minimum readout intervals: 30 s
• Operating temperature range: - 40°C to +105°C
• IP rated: IP65 (hub) / IP68 (sensor)

Dynapar OnSite Analytics. The OnSite System includes OnSite Analytics, a custom-built portal designed to make it possible to harvest insights in minutes rather than weeks. Customizable alarm functions enable even novice users to act ahead of a breakdown.

Built-in tools include:

• Raw data presented as a full-time waveform
• FFT plots for spectral analysis
• Waterfall plots to view evolution of features over time
• Harmonic cursors to investigate specific parameters at any point on a curve
• RMS trendlines
• Persistent data storage for comparison over minutes, to months, to years Built-in OnSite Analytics tools include:
• Passwords are encrypted and hashed, and no modifications need to be made to existing IT firewalls. OnSite Analytics enables client devices to access data and analytic tools just by signing into a web portal. There is no need to download an application in order to use the system.

With the OnSite CMS, productivity is no longer hostage to issues like bearing defects, lubrication breakdown or undersized gearboxes. Now, third-party consultants, service providers and maintenance technicians can confirm the health of assets on a moment-by-moment basis. They can replace “milk runs” with strategic route-based monitoring. They can plan their maintenance schedules with confidence, secure in the knowledge that any issues will be discovered well before they shut down the line or cause catastrophic failure.
