functions. With the Centum system, a prominently
colored tag mark is displayed on the HMI screen
next to any measurement reading that falls outside
the normal range. With Centum VP R5.04, these colored
tag marks now come in a variety of easily recognizable
shapes that indicate the importance of a
measurement item and the severity of an anomaly
(critical, high-risk, medium-risk, low-risk and so on).
New audible alarms have also been added to provide
information on the severity and equipment location
of an anomaly. Through the use of color, shape and
sound, operators can quickly and intuitively recognize
the significance of a specific alarm, thereby allowing
for improved operational safety. - Yokogawa Corp. of

Tank cleaning in explosion-proof zones
By means of high-pressure water, various incrustations
can be removed inside of autoclaves, reactors, spray
towers and vessels. The pump unit discharges highpressure
water (up to 1,600 bars) through the company's
Tank Cleaning Head Nozzles (photo). The water jet cuts
through the deposits, removing hard incrustations by
means of precise rotating movement, thus reaching the
inner surfaces in an optimal way. Thanks to their examination
certificate according to EC directive 94/9/EC
for category 1, the tank-cleaning heads series TWK are
permitted to be used in explosion-proof areas zone 0 and
zone 20. Optimized displacement circle diameter allows
the use of cleaning heads even with small access openings.

This valve controller is suited
for hostile environments
The Fisher Fieldview DVC6200p series of digital valve
controllers is an ideal solution for applications in which
accessibility, extreme temperatures (up to 120°C),
extreme vibration or confined space make integral
mounting difficult or impractical. Industries such as
pulp and paper, and metal and mining have typically
preferred to isolate valve-mounted instruments from
harsh environments. With the remote-mount version of
DVC6200p, only the valve position feedback is mounted
on the control valve, while the remainder of the digital
valve controller can be mounted over 90 m away in a
less severe or more accessible environment. - Emerson
