Chlorine Sensors Simplify Water Monitoring
 The
FCA-22 Free Chlorine Sensor, TCA-22 Total Chlorine Sensor and CDA-22
Chlorine Dioxide Sensor are high-accuracy amperometric sensors ideal for
fresh water applications including monitoring of industrial cooling and
rinse water, drinking water and wastewater. The FCA-22 is a
low-maintenance, high-accuracy amperometric free chlorine sensor ideal
for most aqueous environments. It features a long-lasting sensor that
minimizes part replacement and precisely measures free residual chlorine
from 0.05 to 20.0 ppm Cl2, 5 to 9 pH and at temperatures from 32 to
122°F (0 to 50°C). The TCA-22 Total Chlorine Sensor is designed for use
in drinking water, industrial cooling and rinse water, wastewater or
other fresh water samples containing chlorine in the range of 0-20 ppm,
operating at a temperature range of 0-45°C. The amperometric sensor
features a three-electrode design that measures all chlorine species in
the water, combined chlorine and free chlorine. The sensor is
constructed with one gold cathode, one silver halide anode and a 304
stainless steel counter electrode which provides a stable base
potential, minimizing drift for higher accuracy. The CDA-22 is a
high-accuracy polarographic amperometric sensor with gold cathode and
silver chloride anode and PTFE membrane. It designed to measure chlorine
dioxide in concentrations ranging from 0.05-20 ppm CIO2 and operates at
a wide temperature range of 0 to 50ºC (32 to 122ºF). It is ideal for
applications in municipal water systems, industrial cooling and rinse
water, wastewater or other fresh water samples. The low-maintenance
CDA-22 can run for up to one year between electrolyte/membrane changes.

Industrial 900 Series Operator Workstations are built to withstand even
the harshest oilfield operating conditions, including high shock and
vibration. The 15 in. or 19 in. monitors are encased in a thin but
rugged NEMA 4/4x stainless or painted steel slim housing suitable for
Class I, Division 2 hazardous area installation. The robust enclosure
design mitigates heat without the need for venting or cooling fans. The
workstations feature glove-friendly touchscreens, and are available in
transflective models for clear outdoor viewing. These industrial
workstations can be ordered to meet the existing communication
infrastructure of the application. The standard connectivity provided is
Cat 5 or fiber-based KVM Monitors, Ethernet Remote Network Monitor or
Full Panel PC. Their adaptable design enables operator workstations
throughout the processing facility to have a consistent look and feel,
but with different functions.
AutomationDirect
is expanding its line of industrial relays to accommodate a wider range
of applications. The APR40 series power relays, available in SPDT, DPST,
and DPDT models, feature open-construction design with high-power
contacts capable of switching up to 40A with a maximum contact voltage
up to 600V. H782/H750 series Hazardous Location electromechanical relays
are hermetically sealed plug-in style control relays designed for
applications requiring sealed units for hazardous factory locations.
Both series feature high vibration and shock resistance providing high
reliability and long life and are available with relay coil voltages of
110/120 VAC, 220 VAC, 12V AC/DC and 24V AC/DC. The H782 series 4PDT cube
relays come in 3 Amp and 5 Amp models, while H750 series octal relays
feature 12 Amp contact ratings and are available in DPDT and 3DPT
models. The Solid State Relay (SSR) line has been extended to include
the AD-SSR6 series panel mount relays. This series offers Class 6 solid
state relays which withstand high load ratings from 10 Amps up to 75
Amps in a finger-safe “hockey puck” type housing. Switching types
include DC switching for low-voltage DC loads and Zero Cross for
resistive AC loads. The AD-SSR8 series features general purpose solid
state relays which offer energy efficient current switching in a slim
housing ideal for space-saving applications. The series has input ranges
of 90 to 280 VAC and 3 to 32 VDC. The DIN rail mountable relays feature
internal heat sink, optically coupled circuits and finger-safe
terminals. Switching types include Zero Cross for resistive AC loads
where the output energizes/de-energizes when control voltage nears zero
and Random for AC loads where the output changes instantaneously with
the actual voltage. The AD-HSSR8 series HAZLOC solid state relays are
Class 8 hazardous location relays approved for Class 1, Div. 2 (Groups
A, B, C, D). Switching types include DC switching for DC loads and Zero
Cross for resistive AC loads. Switching devices include MOFSET for DC
loads and SCR for all types of AC loads. They are available in 8 Amp to
15 Amp contact ratings.
