At a Glance Overview

The VCM-3 is the cost effective 12 channel data acquisition hub targeted at monitoring of auxiliary machines, balance-of-plant (BOP) machines and less critical assets as part of enterprise Industry 4.0 digitization efforts. Multiple VCM-3 monitors can be connected to your network with wired technology providing the next generation of asset condition monitoring without batteries or spotty occasional monitoring provided by route based or multiplexed systems.

The monitor devices are robust, simple to install, and provide industry standard CCS (Constant Current Supply) acceleration sensor inputs and power. Along with advanced signal processing the VCM-3 provides extensive alarm capability. For trouble shooting and commissioning purposes for each channel and main descriptor a spectra (FFT) type data plot can be accessed via the built-in VCM-3 Homepage (Web server).

The VCM-3 will end your frustration monitoring your balance-of-plant (BOP) and smaller less critical machines. These machines are often difficult to identify and diagnose potential problems especially with the periodic low bandwidth data provided by most existing systems. These machines need high fidelity continuous data streams for effective monitoring. Whether your monitoring strategy uses alternative on-premise or internal VCM-3 descriptor alarming

- for instance to comply to ISO 10816 respectively 20816 standard - be ready for a step change down in in the cost of maintaining and understanding your less critical machines.

VIBRO Condition Monitoring 3 (VCM-3)

Spanning the gap between periodic monitoring with data collectors and wireless sensors and the need for continuously connected assets managed 24/7 for reliability and plant optimization. The VCM-3 provides continuous monitoring of BOP and spared equipment in a wide range of industries. Often these mechanical assets are naturally located with multiple machines in close proximity. The VCM-3 is ideal for continuously monitoring up to four (or even six) machines -typically being equipped with two bearings- utilizing the twelve dynamic vibration signal inputs.

This data is concentrated into a single network stream using Modbus TCP Server or OPC UA Server acting as a functional edge device powering the enterprise digital transformation.

NOTE, the VCM-3 has an integrated OPC UA Server functionality in the hardware. All measurement, alarm and status data can be transferred directly from the VCM-3 hardware to an OPC UA Client application. Thanks to the built-in network switch functionality, no additional external Ethernet switch hardware is required when integrating multiple VCM-3 devices. The available optical SFP network connector supports a stable long distance network connection.

The VCM-3 processes advanced descriptors which are extracted key features from parallel AD processing for direct monitoring of roller element bearings (REB). Use of modern electronic design elements allows the VCM-3 to provide continuous monitoring of the 12 channels of sensor input at a very competitive cost point that will help you accelerating your enterprise’s digital transformation.

Key Features and System Benefits

 Fault detection – Descriptors for trending

VCM-3 is using descriptors for fault detection. A descriptor is created by post processing the raw vibration (sensor) signal into one or more scalar values. A descriptor value is very well suited for long term trending to indicate failure modes of machines. VCM-3 measures a range of descriptors such as real time standardized bandpass filters for true energy measurements, and envelope bandpass for bearing fault detection.

 High number of input channels/High value

Suitable for advanced condition monitoring of several machines in one device. All input channels are sampled simultaneously (synchronous sampling).

 12 Dynamic vibration input channels,

sampled at 204,8K samples per second via 24 Bit analog to digital converter (ADC)

 Field mountable edge device

Environmentally robust -40 to +60 °C (-40F to +140F) operation with built in protocols for MODBUS TCP and OPC UA. VCM-3 can be installed as field monitors mounted at remote locations next to the machines* or in an instrument cabinet.

*in a suitable field housing

 Robust cybersecurity

The ports in our VCM-3 hardware have been hardened with encryption and designed to push data out to upper networks without exposing critical infrastructure to external vulnerabilities. It is specifically designed to work with firewalls, data diodes, and multi-tiered networks to meet industry’s most stringent data security requirements

 OPC UA Server embedded in the device

Remove the need for additional software and PC/Server hardware infrastructure for the OPC UA Server application as OPC UA is embedded directly into the VCM-3 hardware device.

 VCM-3 Homepage (embedded Web server)

Acceleration/Velocity spectrum and Envelope spectrum plot (all FFT, Hanning Window) can be accessed for each of the 12 dynamic vibration input channels via the built-in Homepage (Web server). This can perfectly be used for commissioning or remote diagnostic access use cases.

 Field proven

Based off the third generation of the world’s most popular wind turbine monitoring system with over tens of thousands installed units.

 Rolling Element Bearing (REB) descriptors

 Acceleration band pass with flexible filter

corners (simultaneously measured detectors rms, peak, crest factor)

 Velocity (integrated from acceleration)

with flexible filter corners (rms, ISO 10816 / ISO 20816 support)

 Enveloped Bearing Condition ECU with

flexible filter corners

 Designed for the future

(without change of VCM-3 device hardware)

The computational power, the existing sensor input and analysis capabilities, and the flexibility in the design make VCM-3 a technology leader for many years to come. Supports any state-of-the-art condition monitoring method and provides a platform for customizations and development of future new monitoring methods.

VCM-3 System Components

A VCM-3 system consists of the following basic components:

 VCM-3 device hardware  VCM-3 Homepage

(built-in Web server)

 VCM-3 Editor

(Software application to set up the configurable parameters of a Standard Monitoring Template and download to the VCM-3 Web server)

NOTE!

To start up a VCM-3, a personal computer (PC) with Microsoft Windows operating system is required. For more information please consult the dedicated section Ordering Information and VCM-3 Editor – PC and Software Requirements at the end of this document.

Fault detection, Trending and Identification

The VCM-3 has been designed to continuously acquire different characteristic values from the sensor raw input signal of the connected sensor. Each of these characteristic values are captured as a “Descriptor”. In future version releases, descriptors can be customized to accurately monitor for specific component failure modes. An increase in the level of a descriptor is a symptom of a developing fault on the machine. A descriptor respectively series may be the ECU value, which indicates a bearing fault. A descriptor value may also be used to express the severity of the vibration level of the component compared to international standards such as ISO

10816. The powerful inbuilt signal processing capabilities enables the VCM-3 to extract a number of descriptors measured simultaneously on the independent measurement channels.

Experience shows that long term trending on the each of the descriptors derived from the input signal provides a very sensitive measure of the operational state of the machine and gives an early indication of a progressing fault, thus maximizing lead time to plan a service shutdown or to provide enough evidence to postpone a repair to the next scheduled shutdown.

Monitoring Templates

The configuration of the VCM-3 hardware units is organized in “Monitoring Templates”.

The VCM-3 can be loaded with different monitoring templates implementing a specific monitoring strategy adapted to the type of machine and monitoring requirements without the need for changing the hardware.

Standard Monitoring Template

To simplify the system set up work a set of two Standard (Master) Monitoring Templates- is supplied together with the VCM-3 System. Each of these templates has been developed to cover applications for the following types of machinery:

Technical Specification – Standard Monitoring Template

The VCM-3 input channels enable acceleration sensors (CCS, Constant Current Supply) to be used as signal inputs. The table below shows how each channel of the VCM-3 is configured for each of the available Standard Monitoring Templates. All descriptors on all measurement channels are measured in parallel (simultaneously) and are continuously updated.
