General Description

 

The WiVib-4/4 Pro from Icon Research is a wireless multi-channel vibration monitoring device that operates on the universal WiFi 802.11b/g standard. This new device offers simultaneous sampling on its four dynamic channels at 24-bit resolution and up to 102.4kHz sample rate with 12800 spectral line resolution. The additional four DC channels are ideal for measuring process parameters. For example, accelerometers with temperature output can be connected directly to the unit enabling vibration, bearing condition and bearing temperature to be measured.

The WiVib-4/4 Pro incorporates an ICP power supply on each of its four dynamic channels so that any standard 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” as it is sometimes called. 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.

The two digital 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, and gates for conditional initiation of measurements. One of the triggers can be configured to act as an analog trigger input.

The WiVib-4/4 Pro operates on the universal WiFi 802.11b/g standard and offers full WEP, WPA and WPA2 security. Network configuration is straightforward by connecting to the on-board USB port and running the WiVibConfig software utility supplied on any laptop or PC.

Power is provided by two internal ‘C’ size batteries or a DC supply in the range 10 to 30V. Under battery power, the device requires no connections apart from the sensors and it can be powered up and down by its internal real-time-clock.

The unit has been designed for operation in hazardous locations and is approved for use in ATEX Zone 2 areas. It is currently going through Class 1 Div 2 certification for use in North America. The unit is housed in a compact rugged enclosure and is sealed to IP67. It is fitted with stainless steel brackets for easy mounting. The twelve sealed glands allow cables of varying diameter to be routed to the unit.

The WiVib-4/4 Pro is supplied with a comprehensive suite of support software enabling the device to be configured on your network and useful measurements to be taken right away .
