ROUND UP
High performance
digital camera for
hazardous areas
E
xtronics, designer and manufacturer of
intrinsically safe and explosion proof
equipment, has made available a new digital
camera for hazardous areas - the iCAM502.
Building on the outstanding success of the
original iCAM501, this latest model has a
number of significant new enhancements
designed for users with high performance
requirements.
The new auto-focus lens allows crystal-
clear images to be taken from as close as
5 cm. This makes the iCAM502 ideal for
taking pictures of rating plates, close-ups of
wiring cabinets etc.The auto-focus lens also
provides pin sharp images at all distances
and the improved white balance further
enhances picture performance.
A key feature of the iCAM50x series has
been its highly portable and lightweight
form factor - less than 200 g.This is achieved
by allowing image quality feedback via the
camera's three LED lights. This powerful
feature has been enhanced in the iCAM502
which carries the latest image analysis soft-
ware, providing greatly improved picture
quality, speed of shot and overall camera
performance. The camera also comes with
a removable rubber casing which enhances
durability and grip whilst retaining portabil-
ity and ease of use.
"The iCAM501 Ultra
continues to be an out-
standing success for
Extronics due to its
cost-effective combi-
nation of portability
and performance," said
John Hartley, manag-
ing director at Extron-
ics. "The new iCAM502
builds on that success
and is designed for those
customers demanding
improved picture perfor-
mance, particularly close-
up images."

Hazardous areas and safety
K
eller, manufacturer of measuring technology - represented in southern Africa by
In-
strotech
- has a complete range of pressure transmitters for use in hazardous areas.
These intrinsically safe transmitters offer measurement ranges of between 0,2 bar and
1 000 bar, so they can be used for measurements of all types in areas subject to explosion
hazards in Group II (gas), and as per the relevant ATEX Directive. Individual types from
the product range are also approved for Group I (mining) respec¬tively Group II (dust).
Common features of allY-line pressure transmitters include a very low temperature error,
with correspondingly high measure¬ment accuracy.Thanks to the integrated temperature
sensor and an additional digital circuit, the range of envisaged opera¬ting temperatures
can be divided into as many as 120 sections with a width of 1,5 Kelvin. During factory
calibration, a mathe¬matical model is used to calculate individual compensation values
forTK zero point andTK amplification for each of these sections; the values are then stored
in the transmitter. During operation, these values are fed into the analogue signal path
according to the temperature, without reducing the 2 kHz signal processing dynamic. A
relevant total error band for measure¬ment purposes of ±0,8% FS can therefore be attained
over the typical temperature range of -10°C to +80°C.
