WiVib Wireless Condition Monitoring

WiVib Wireless Condition Monitoring. The WiVib family of vibration acquisition units from Icon Research provides wireless and ethernet multi‐channel vibration monitoring on standard networks. The WiVib range communicates via the WiFi 802.11 standard and is fully compatible with all low‐cost access points and accessories used on this popular medium, including full security.

Ethernet connectivity is also provided for convenient hooking up to cable networks where they are available. The devices can be powered from permanent external power or from internal batteries. We invite you to browse the specifications of these devices to fully appreciate the powerful features available for wireless condition monitoring.

Wireless Condition Monitoring System

WLAN & LAN Standards

WiVib devices operate on standard WLAN and LAN networks. The WiVib-4/4 Pro operates on the 802.11 b/g/n standard while the WiVib-8/8 Pro operates on both 802.11 b/g/n and 100BASE-T Ethernet. Standard security protocols are supported. Setting up on your network is straightforward using the WiVibConfig utility app.


The devices offer simultaneous sampling on all dynamic channels at 24-bit resolution and up to 102.4kHz sample rate with 12800 spectral line resolution.  The additional DC channels are ideal for measuring process parameters.

Accelerometers with temperature output can be connected directly to the units enabling vibration, bearing condition and bearing temperature to be measured.

An ICP power supply is incorporated on each of the dynamic channels so that any compatible accelerometer can be connected.  Alternatively, the inputs can be AC coupled to interface with buffered signals from other systems.  High-resolution acceleration and velocity measurements can be made, together with bearing condition using the built-in demodulator or “enveloper”.

Accelerometer bias voltage checking is incorporated.  The dynamic inputs are also compatible with standard eddy current (proximity) probes allowing direct measurement of displacement, including gap voltage.


Digital and analog trigger inputs offer flexible triggering options allowing synchronised readings to be taken.  The triggers can also be configured to operate as tachometer inputs, PLL’s for ordered spectra (on the WiVib-8/8 Pro only), and gates for conditional initiation of measurements.


WiVib’s can be powered from a low voltage supply in the range 10-30Vdc, or from internal batteries. To conserve battery life, the devices can operate in wakeup mode, whereby measurements are taken at specified intervals, and then the device goes to sleep to conserve battery power.

WiVib Wireless Condition Monitoring Software Support Applications

The WiVib range of hardware is supported by three software applications, namely:

  • WIVibConfig – a utility that enables a WiVib device to be configured onto a network, either wirelessly or on ethernet.
  • WiVibScope – an application that turns a WiVib into a fully featured oscilloscope and spectrum analyser.
  • WiVibTrend Lite – an application that enables continuous monitoring of plant and machinery with full alarming, trending and analysis functions.


Configuring your WiVib’s to communicate on a wireless network is made easy with the WiVibConfig utility. Simply edit the network settings (eg. IP address, SSID etc) and then click Save and Connect to enable the WiVib onto your network.

The panel on the right monitors network activity so you can quickly see if the WiVib has connected to your network, or if further editing of the settings is required. Security settings can be entered and modified as required. Configurations can be saved to file and reloaded so you don’t have to re-type all of your settings each time you introduce a new WiVib onto your network. Communication is via a cable from any USB port on your laptop or PC.


WiVibScope enables both time and spectrum graphs to be displayed from any selected channel of a WiVib. Measurements can be displayed in standard engineering units such as g and ips as well as user-defined units. Simply select the WiVib and the channels that you want to monitor and live traces stream to the high-resolution display.

Zoom and cursor with readout function are provided.

Settings such as number of spectral lines, bandwidth etc are easily changed with drop-down menus. Any acquisition setting (eg. gain, integration to velocity etc) can be adjusted also.
WiVibScope is ideal for detailed analysis, system checks and installation setup. Both continuous and wakeup modes are supported.

WiVibTrend Lite

WiVibTrend Lite provides the core functionality of on-line monitoring systems with features such as trending, alert/alarm indication and full analysis capability. It can support any number of channels with multiple measurements (for example, velocity vibration and bearing condition) being available on each channel. An OPC server is incorporated for export of measurement data to factory-wide systems. Its straightforward setup-and-go interface means that you can be logging and trending within minutes of loading the application.

A moving chart-recorder updates current measurements while historical pan and zoom functions let you examine previously measured data.

This application is ideal for smaller stand-alone wireless on-line systems while larger installations can utilize the OPC feature.

WiVibTrend Lite supports a simple Plant … Machine … Point … Measurement hierarchy. Alerts and alarms are indicated on the hierarchy and summarised in the table underneath. The red/yellow/green traffic light summary lets you know the status of your plant at a glance. The application supports wakeup and continuous modes on the WiVib’s, so you can choose how often you want to scan your machinery. This can be from several times a minute to once a day. A historical trace, such as a spectrum, can be viewed by selecting the time at which it was gathered on the trend graph. Alternatively, live/latest spectra can be viewed with full cursor readout.

Setting up the machine hierarchy is very straightforward. First, use WiVibConfig to connect your WiVibs to the network and then use the single screen setup in WiVibTrend Lite to specify what you want to measure and when. Hardcopies of trends and traces can be printed, or traces can be written to file for emailing or inserting in reports.

WiVib hardware and WiVibTrend Lite software combine to produce a powerful machinery monitoring package that is low-cost, quick to install and easy to use. WiVibTrend Lite has been developed by Icon Research to exploit the advantages that wireless monitoring brings to industry. You can get started with a single WiVib and be monitoring your plant within minutes.
