Dynatrol
A proportional level-output
detector for pilot plants
The Dynatrol CL-10GP proportional
level detector (photo) is designed to
control liquid levels in pilot plants,
chemical-processing plants and
small vessels, or anywhere it is necessary
to obtain proportional

control over a precise range. The EC103C(G)
control unit is paired with
the detector and can activate electropneumatic
transducers, valve positioners,
indicators, controllers or other
direct-current devices. The detector
and control unit accurately monitor
and control an extremely precise liquid
level range due to its unique, highresolution,
proportional output signal.
This unique control operates reliably
under varying-frequency power supplies
or harsh process conditions,
such as high pressures and high temperatures.
All units are built in accordance
with Class I, Group D; Class
II, Groups E, F & G; and Class III services.

Electro-Chemical Devices
Determine sulfur and nitrogen
content in gases and liquids
Launched under this company's
Antek brand, ElemeNtS is said to be
the most advanced modular-analytical
system available for the detection
of total nitrogen or total sulfur
(or both) content in liquid or gaseous
materials and liquified propane gas
(LPG) samples. Three configurations
are available: ElemeNtS-N for
nitrogen analysis, ElemeNtS-S for
sulfur analysis and ElemeNtS-N/S
for simultaneous nitrogen and sulfur
analysis. ElemeNtS combines
extremely stable sulfur and nitrogen
detectors with linearity up to 104.
The new generation ElemeNtS displays
exceptional sensitivity and allows
simultaneous analysis of total
sulfur and total nitrogen in hydrocarbon
samples up to 30 parts per billion
by weight (ppbw), according to
ISO 11843. Featuring a 10 in. touchscreen,
the ElemeNtS allows for direct
queue control and diagnostics,
along with a completely revamped

This ICP-OES analyzer is now
twice as sensitive
The new Spectrogreen inductively
coupled plasma, optical-emission
spectrometry (ICP-OES) analyzer
(photo) features a revolutionary Dual
Side-On Interface (DSOI) technology
that achieves twice the sensitivity
of conventional radial-plasma-view
instruments, at an attractive price/
performance ratio. DSOI technology,
a brand-new approach to the critical
issue of plasma view design, uses a
vertical plasma torch, observed via
a new direct radial-view technology.
Two optical interfaces capture emitted
light from both sides of the plasma,
using only a single extra reflection,
for added sensitivity and elimination
of issues that plague newer verticaltorch
dual-view models. As a result,
DSOI provides twice the sensitivity of
conventional radial systems and yet
avoids the complexity, drawbacks
and cost of vertical dual-view models.

A cyanide analyzer for
industrial wastewater
The S80-T80 cyanide analyzer
monitoring system (photo) features
an S80 Pion Cyanide Sensor and
a dual-channel T80 Transmitter.
The cyanide analyzer helps plants
achieve a more cost-effective cyanide-removal
water-treatment system,
which ensures wastewater is
treated to meet U.S. Environmental
Protection Agency (EPA) regulatory
requirements prior to effluent
discharge.
The S80's CN-ion electrode
is a combination electrode with a silver
cyanide/silver sulfide solid-state
pressed-crystal sensing element and
a double junction reference electrode.
The CN-ion selective electrode
cartridge develops a millivolt
potential proportional to the concentration
of free CN ions in the mea
