New family of portable data-acquisition systems are designed
for use in tough environments
 Kenda
Electronic Systems Ltd has unveiled a new family of portable
data acquisition multianalysers that are suitable for use in
a variety of equipment-monitoring applications in the military,
aerospace and maritime sectors.
The multianalyser family initially consists of two models -
the PDA-32 and the PDA-96 - both of which feature rugged, weather-sealed
housings to enable them to withstand the rigours of the most
demanding environments.
Designed to record analogue signals from multiple sensors on
to a hard disk, the new units are equipped with a 16-bit ADC
capable of a sampling frequency of up to 180kHz, together with
optional 4-channel 12-bit DAC outputs.
The PDA-32 is the smaller of the two units, with overall dimensions
of 206 x 158 x 138mm and a weight of just 3kg. Housed in an
injection-moulded glass-loaded ABS case, it provides 32 analogue
input channels, a removable hard disk drive and a 4in. touch-screen
TFT display offering 640 x 480 pixel resolution.
Its 96-channel stablemate, the PDA-96, measures 470 x 370 x
200mm and weighs 12.5kg. This model features a detachable full-size
keyboard with built-in trackerball and a 1024 x 768 pixel 10.4in.
TFT display, which is hinged to allow wide adjustment of the
viewing angle.
Operating under Windows NT, both models are supplied complete
with Kenda's OptiMal analysis software, which can execute tasks
such as Fourier Transforms, polar plots, vector analysis, graphical
representation, twin cursor zooming and direct measurement.
The software also enables the units to be pre-programmed to
start recording or to initiate other activities at specified
times or in response to a range of trigger criteria based on
signal behaviour.
Data can be downloaded to an external PC using the multianalysers'
Ethernet LAN ports or serial interfaces.
