Gubras

The guardian for rotating equipment

A state-of-the-art solution for predictive maintenance and condition monitoring of rotating equipment.

Gubras Matrix

Gubras Matrix is our DAQ solution that can read and process data from up to 64 sensors. It does so through up to 16 DAQ cards that have four channels each. The sensor signals are converted to digital at a sample rate of 3600 samples per crank revolution, which is especially required for vibration sensors. The system is also capable of connecting to analog outputs of other DAQ systems such as BN3500 and receiving their sensor data directly.

Gubras Kernel

Gubras Kernel is a powerful gateway in charge of receiving data from the DAQ systems and the DCS, aggregating and storing the data, calculating performance parameters, and performing fault detection and fault isolation algorithms, as well as sending the reports, data, alerts, and results to our user interface.

Gubras Kernel

Gubras Visage is our main user interface. It utilizes different real-time 2d and 3d charts and models, as well as multiple trend analysis methods and function to provide all the tools required for predictive maintenance and condition monitoring of rotating equipment.

Beyond Protection

Comprehensive monitoring

Gubras allows monitoring many different types of measurements including pressure and temperature at different points, vibration at different locations, proximity sensors, as well as oil level sensors. These sets of measurements are sufficient for monitoring any type of rotating equipment.

Component model

Modeling the equipment in a tree structure. The tree structure not only displays the component breakdown, but also displays all parameters, available functions, the status of components, and sensors in the same component hierarchy.

Reciprocating compressors solution

More than 15 types of measurements defined for reciprocating compressors. More than 70 performance parameters are defined in our reciprocating compressor module and calculated in real-time, which form the basis for detecting more than 15 different faults, such as valve leakage, valve fluttering, valve sticking, rider ring wear, looseness, and imbalance. Our software not only plots the cylinder dynamic pressure against displace volume, but also detects important points on the plot, such as valve closures and the beginning and end of compression and expansion stages.

Scalability

Gubras can monitor up to 64 sensors per each Gubras Matrix assembly. We have a variety of four-channel DAQ cards: some for specific functions, and some that can read data from any 4-20mA or 0-10v sensor. The design allows condition monitoring of smaller equipment with minimum number of DAQ cards.

Full customer support

Our team of experts provide support in the form of periodically analyzing the equipment performance and suggest measures to prevent faults. We also guide customers into diagnosing their equipment and improving the equipment performance. We provide extensive training for your staff. We teach your staff on how to work and interact with the Gubras software. We also provide technical courses on how to analyze the parameters, diagnosis messages, and reports generated by Gubras.

Portable solution

Gubras Portable is the ideal solution for diagnostics and fault isolation of smaller equipment or fleet monitoring. The portable version connects to four sensors simultaneously, two for 4-20mA sensors and two for 0-10v sensors and can store data offline or on the cloud for future detailed analysis, while connecting to Gubras Visage on a wireless device to display real-time charts and basic analysis.

Step 1

The P&ID and equipment data sheets provided by the client are analyzed. To provide predictive maintenance for most rotating equipment, more sensors are needed than what is already available for protection systems. Depending on the use-case and budget, additional sensors and cabling may be suggested.

Step 2

The component model for the client’s equipment is built. This includes listing required parameters, alerts, and algorithms. If available, sample performance data is analyzed and based on the results, the predictive maintenance models and RCA decision trees are developed to be ready for the training phase.

Step 3

Sensors and the DAQ system are installed and Gubras is connected to other data sources such as DCS. Tests and early training of the predictive maintenance and RCA algorithms are performed to tune the parameter and threshold formulas and diagnosis methods.
