Dynapar OnSite™ Condition Monitoring System-Reinvented

The Dynapar OnSiteTM Condition Monitoring System Delivers Feature-Rich Performance

The Dynapar OnSiteTM Condition Monitoring System is changing what it means to track machine health. Designed to deploy in minutes, the Four/Five-sensor device combines affordable, remote 24/7 condition monitoring with cloud-based analytic software for multi- stakeholder access. Today’s lean market puts ever greater emphasis on maximising uptime. Savvy plant managers, reliability engineers, and maintenance managers understand the importance of condition monitoring to achieving this goal. Unfortunately, previous market solutions have always 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.

“Democratising condition monitoring” – making this powerful tool accessible to end users and third-party predictive maintenance providers. Customers asked for a practical solution to monitor their critical assets, their bad actors, and their hard-to-reach equipment. The OnSite System puts powerful insights at their fingertips.

 

The Dynapar OnSiteTM Condition Monitoring System combines ease-of-use with sophisticated functionality in a surprisingly economical solution. It features Four/Five sensors that each measure vibration along three axes, plus temperature and Speed. It can also connect to an encoder, integrating speed to enhance analytics and troubleshooting. The wireless OnSite System enables organisations to 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. The OnSite System finally makes it practical to monitor as many assets as necessary (fans, pumps, gear boxes, etc).

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 organisation, or third-party service provider can be analysing real-time data from the equipment. And they can do it from any location, be that across the plant or across the world. They simply log into the password- protected web app using their computer, tablet, or smart phone. In the event the asset begins to exhibit abnormal behaviour, users will receive email alerts, thanks to a customisable alarming function. In this way, manufacturers can catch problems before they lead to downtime.

Hardware is only one part of the value proposition. The Dynapar OnSiteTM 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. Leveraging existing wireless or cellular networks, the system incorporates robust security and operates with existing firewalls, making it appealing to IT departments.

The OnSite System is already established in multiple production environments. Installations include paper processing, converting, steel manufacturing, and more. “In less than three months, our early adopters have already realised their return on investment. “The OnSite System has helped prevent line stoppages and avoid unscheduled maintenance.”

Dynapar OnSite Sensor Hub

The hardware consists of a central hub that aggregates data from four separate wired sensors. Each of these 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.

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)
  • Wireless Range: 250 m

 

Dynapar OnSiteTM Analytics

The OnSite Condition Monitoring System includes OnSite Analytics, a custom-built portal designed to make it possible to harvest insights in minutes rather than weeks. Customisable alarming 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

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 Condition Monitoring System, 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.

“OnSiteTM Analytics are helping clients to transition from a reactive mindset to a much more proactive one.” This also is enabling third-party reliability service providers to offer 24/7 condition monitoring as a service.

With the OnSite Condition Monitoring System, we are transforming the traditional way of working. We call it condition monitoring, “reinvented.”

Dynapar ACURO absolute encoders

acruo-2

The Danaher Industrial Controls Group (DICG) announced an expansion of its Dynapar ACURO series of absolute encoders with two new models that incorporate the company’s new opto-ASIC technology platform. ACURO is already a market leader in several key performance metrics, such as communication compatibility, networking speed, high resolution, and lowest current draw, among others.

The application / function are as follows:
The new opto-ASIC platform extended throughout the ACURO line now provides advantages that make absolute encoder technology applicable to a wider range of motion control and servomotor feedback applications. The new ACURO 36 and ACURO 110 models extend the ACURO series to applications in the small motor, packaging and textile machinery, and medical equipment sectors.

Absolute encoders improve machine reliability because, unlike incremental encoders, they always know their position, even at startup or after a power failure. DICG technology and manufacturing breakthroughs have reduced the cost of absolute encoders, so that they are now finding acceptance in every kind of application, not just the high end, demanding few.

Broader range of sizes – Only 36mm in diameter, the new hollowshaft ACURO 36 encoder is more than a third smaller than previous models in the ACURO line. At 110mm, the new hollowshaft ACURO 110 encoder accepts shaft sizes up to 50mm. Both are available in motor drive or standard industrial versions.

Low-profile gears shrink size, increase reliability – The ACURO 36 is one of the few encoders that use a gearbox instead of a battery to provide multiturn resolution. The low-profile mechanical gearbox allows a lower installation height than battery-buffered counter solutions.

Thin as a dime, the gear set facilitates an installation depth of just 31 mm – one of the shortest in the industry. Small encoders are especially important to motor OEMs, who are under pressure to continually shrink their designs.

In addition, the gears eliminate dead batteries as a potential source of downtime, and eliminate the need for battery maintenance. Running at speeds up to 12,000 rpm, the gear set is nonmagnetic and immune to interference in such applications as welding or motors equipped with powerful brakes.

New OPTO-ASIC generation platform:
The ACURO 36 and ACURO 110 encoders are based on DICG’s new generation platform based on opto-ASIC electronics, into which multiple functions are highly integrated. ACURO was engineered for field dependability, re-designed from the predecessor’s 150 parts and five circuit boards to less than 30 parts and just one board. Reliability is enhanced by minimizing the number of printed circuit boards and soldered connections. The new electronics also enabled Danaher designers to increase the temperature specs on the motor drive version to an industry-leading 120 degrees C – ideal for today’s smaller, hotter running motors.

The ACURO Series has the lowest current draw of any absolute encoder, at just 45mA for the single-turn version and 85mA for the multiturn version.

The new platform is consistent across DICG’s manufacturing plants worldwide. Globally based companies are assured of receiving the same design encoder no matter which region it was manufactured in. This allows company managers to reduce costs through component standardization.

The most communications protocols -The ACURO Series encoders can communicate with any type of control system using common formats, ranging from parallel to such field buses as profibus, DeviceNet, CANopen, CAN Layer2 Interbus, and SSI.A 2048-step sine/cosine signal (1Vpp) is also available for dynamic control. No other encoder offers as many communication options.

Network speeds five times faster:
The ACURO Series was the first to use the new BiSS (Bidirectional Synchronous Serial Interface) protocol. This freely licensable, open-standard protocol supports networking speeds five times faster than proprietary encoder protocols. Using the BiSS protocol, engineers free themselves from restrictive, proprietary bus standards, and achieve data throughput up to 10Mbaud using standard drivers and cables longer than 50m.

As BiSS is all digital, it eliminates the added cost of A/D converters needed in drive systems that connect to encoders using proprietary protocols. BiSS is hardware-compatible with the SSI protocol, simplifying integration.

Differentiate features are:
High accuracy:
The ACURO 36 offers up to 12-bit multiturn and 22-bit single turn resolution – one of the highest accuracy encoders on the market. The ACURO 110 offers 17-bit single turn resolution. High resolution allows precise control of machine motion and increases machine reliability.

More diagnostics than any other encoders:
The new ACURO Series offers more built-in diagnostics and alarms to monitor current and temperature than any other encoder. Optical sensors internally monitor the amplitude of the encoder signals, and exceeding the limit values will result in warning messages. A single-step code check ensures that the encoder signal reflects the recorded turn, bit by bit. The internal signal processing function checks each individual increment for possible occurrence after the previous event. Any violation of this rule, possibly due to disk breakage or mechanical overload, will lead to an alarm.

In addition, a self-monitoring feature checks the operating hours and signals a warning message to initiate preventive maintenance. What’s more, the BiSS protocol can report operation information that can be used diagnostically, such as torque, temperature, and acceleration.

TWK-Inductive Linear Transducers

Inductive Linear Transducers for engineering and instrumentation.

The half-bridge technology for 1 to 360 mm stroke. The wide range of inductive linear transducers includes items with 10, 12 and 25 mm outside diameter and for measuring ranges from 1 to 360 mm. The smaller IW 10 and IW 120 series require external electronic modules for excitation and signal conditioning. IW 250 series with 25 mm housings have integral electronics consisting of oscillator, demodulater and amplifier. Analogue output signals are either 0(4) to 20 mA, 0 to 10 VDC or ± 10 VDC for full range or calibrated strokes. The transducers are completely potted to meet protection grades up to IP 68. Electrical connection is made either by leads, plug and socket or through cable glands. Various mechanical configurations are available to suit specific mounting conditions.

The IW 260 displacement transducers operate according to the new principle of fractional inductivity allotment within the hollow coil. Depending on the position of the core the inductivity changes within the corresponding coil section. This kind of layout provides for more position data than the classical half-bridge or LVDT configuration. An integral electronic circuit transforms these data into a signal proportional to the displacement of the plunger core.

The electronic circuit contains an oscillator, a demodulator, an amplifier and in some cases a current output source. Its SMD-design is short-circuit proof and protected against reverse polarity. The sensor system is completely sealed within a non-corrosive steel case to ensure positive protection against vibration, shock, humidity, oil and corrosive matter.

The new principle of fractional inductivity allotment as described above brings about an outstanding increase of the measuring stroke. In comparison to the IW 250 model the useful range of the IW 260 model increases by 70 to 100% based on the same length of the case.
