The monitoring camera market has been expanding worldwide, driven by the
recent increase in awareness of the need for heightened plant security. To
improve plant safety, monitoring cameras that deliver high performance and
are easy-to-install are in demand. In response to these market needs,
Yokogawa has developed this new FIELDEYE II series all-weather CCD colour
camera for the monitoring of plant facilities and premises. The compact new
FC33U has pan-tilt zoom functionality and is non-explosion-proof. Yokogawa
plans to release an explosion-proof model by the end of this year.

Many plants have security camera systems that allow the monitoring of
production lines and other facilities from locations such as the central
control room. Yokogawa entered this market with the 1997 release of the
FIELDEYE series of all-weather CCD colour cameras. Much smaller and lighter
than other plant monitoring cameras on the market, the products have
acquired a solid track record particularly here in Japan and other Asian
countries, says the company.

In contrast to the FIELDEYE series, which used an aluminium enclosure,
FIELDEYE II series enclosures are made of robust, corrosion-resistant
SUS316L*1 stainless steel. Although stainless steel is about three times
denser than aluminium, the new enclosure weighs about the same as the
aluminium enclosures used on our earlier products thanks to its small size
(made possible by the redesign of camera system components) and the use of a
thin-wall stainless steel casting process. The FC33U is one of the most
compact non-explosion-proof pan-tilt zoom type CCD camera systems on the
market today, and is also one of the lightest products employing a stainless
steel construction. With these characteristics, the FC33U is easier to
install and can be used in a greater variety of locations.

As a standard feature, the camera unit, a core component of this product,
has superior sensitivity (minimum illumination: 0.5 lux*2), zoom
magnification (36× optical and 20× digital), and horizontal resolution
(650 TV lines). As such, it is one of the best-performing plant monitoring
cameras on the market today.

Typical applications include the monitoring of processes and facilities at
oil, petrochemical, chemical, pulp and paper, pharmaceutical, food, and iron
and steel plants, says the company.
