Edge-Enabled Multi-Purpose Vibration Analyzer

The Vibration Signature Analyzer (VSA) offered by MachineSense is an edge-enabled multi-purpose vibration system suitable for both rotating machines and non-rotating machines, and also for vibration monitoring of steel and concrete structures.

The sensor has three main applications—predictive maintenance of both rotating and non-rotating machines (that will need dedicated analytics), tracking impact vibration on structures, like tunnels and bridges, and quality control of products that are impacted by interfering vibration.

The VSA tracks vibration data in both frequency and time domains. The proprietary analytics algorithm of MachineSense monitors and compares the gathered data against a baseline and then establishes the overall health of the machine.

The status of valves, gears, rotors, bearings, and oil is continuously tracked. Apart from allowing users to visualize useful operating metrics, MachineSense can precisely estimate and trigger an alarm about pending machine and component failures. This feature considerably reduces unscheduled downtime caused by equipment.

The sensor can be enabled in event trigger mode for monitoring bridges and other structures. This means that whenever a vehicle is affecting transient vibration, the system will detect vibration solely on impact moments and will examine only the applicable data.

The sensor can be easily fixed to the machine housing through a magnet and continuously quantifies temperature, vibration, magnetic field, and humidity. It is driven by a 24 VDC/110-260 VAC power supply.

The sensor data is sent to a datahub through Bluetooth and (or) SPI, and then transmitted to MachineSense’s local or cloud servers through a router. Datahub can be communicated to a server through LAN or WiFi but if these technologies are unavailable, the optional feature of the GSM/CDMA module can also be utilized.

To reduce network and cloud usage, raw data can be saved in SSD, which can be subsequently accessed through a smartphone app for both visualization and download.

MachineSense’s monitoring solution features the company’s extensive Crystalball™ software that allows users to configure alarms as well as alarm recipients. It offers comprehensive historic data with trend lines relating to the performance of the equipment.

At-a-glance dashboards display the present status of monitored assets by plant or department. Users also receive alerts on actionable maintenance advice which is sent through email or text to remind them about machine maintenance.

Datahub

This single-board computer is capable of real-time data acquisition and processing.

SSD

The SSD stores both processed and raw data to save costs relating to cloud and data. It also features a smartphone app to download raw data, synchronize data with the cloud, and visualize machine parameters.

GSM/CDMA Module

The module serves as a substitute for WiFi/LAN in areas that need data to be transmitted to the cloud at regular intervals or in real time.

ON-Premise Cloud

It offers the services of a cloud-based server by running an application that is on the same system as the user application. ON-Premise Cloud is fundamentally a local server with large storage and computation capabilities. It enables users to get all the advantages of the cloud without allowing the data to go out of factory premises, thus ensuring its complete security.

Along with a higher data rate, the advanced vibration analyzer also includes sophisticated analytic features. It enables users to receive more data about the machine and also provides them with options to track the raw data in both time and frequency domains.

The “Variable mart” helps visualize over 100 analytic parameters and also displays their statistics for a configurable time duration based on the storage options. “Raw data insights” offer batch-wise visualization of raw data in varied statistical plots.

In “Event Trap,” all irregular events are recorded under pre-selected parameter/s together with its FFT and raw data. “FFT” offers the amplitude of vibration that is sorted against frequencies. Therefore, it displays the harmonics of the machine, which is an excellent indicator of anomalies.
