served. Typically, during inert-packaging
efforts, sample packages are
tested at regular intervals and the CO2
levels checked by inserting a hollow
needle to draw out a sample of packaging
gas for analysis. The longer the
read time for CO2 analysis, the more
packages are able to move through
the line before detection indicates the
wrong CO2 level. The Storage Control
Systems Portable Gas Sensor allows
CO2 analyses to be carried out
in seconds, using only a small sample
volume. The portable device uses a
SprintIR InfraRed CO2 sensor from
this company. - Gas Sensing Solutions

Magnetic cylinder sensor is
ideal for robotics applications
The MZCG magnetic cylinder sensor
is designed for position detection in
pneumatic grippers or miniature pneumatic
cylinders that have C-slots. With
a universal housing design, the MZCG
fits into a wide range of C-slots from
the most common manufacturers,
which reduces storage costs and allows
for a more flexible machine design,
says the manufacturer. With an
extremely short housing (just 12.2
mm) and a 90-deg rotated radial cable
connection, this sensor is designed
for small drives. Its patented design
makes mounting quick and easy, says
the company. - Sick AG, Waldrich,

Rugged device monitors
carbon dioxide levels
The Series CDWP Carbon Dioxide
Transmitter (photo) can be utilized
to monitor the CO2 concentration
in applications such as HVAC and
CO2 refrigeration mechanical rooms
or greenhouse gas applications. It
uses a single-beam, dual-wavelength
NDIR sensor, which eliminates light
source aging effects. The Series
CDWP is available in multiple range
limits and comes standard with universal
outputs of 4-20-mA and 0
to 5 or 10 V d.c., for use with most
programmable logic controllers or
building-management systems. The
device uses a IP54-rated housing,
which protects the electronics from
dust and splashed water, while the
powder-painted, die-cast aluminum
housing is said to be an improved
material over polycarbonate housings.
Its electrical connection allows
the user to quickly disconnect the
unit from the power and controller,
resulting in faster and easier cleaning.

is always challenging, as
these fluids can lead to clogged float
mechanisms, blocked fill ports, solid
buildup on moving floats and masked
windows. The new Model 7014 highviscosity
liquid-level sensor (photo)
has a proprietary conductive technology
that is designed for monitoring
highly viscous (water-based) liquids. It
has an electrically sensitive probe surface
and no moving parts or floats, so
there is nothing to clog, wear or freeze,
allowing for a reliable signal reading
while reducing maintenance needs,
according to the manufacturer. The
probe also features wetted parts manufactured
with fluorinated ethylene
propylene (FEP). The smooth sensing
surface can differentiate between

Small-footprint sensing
system meets lab needs
The SensoLab benchtop meters and
configurable kits (photo) offers researchers
a more complete sensing
system to carry out pH/ORP/conductivity
monitoring. The PM1000
pH/ORP meter and CM1000 total
dissolved solids (TDS) meters pair
with the company's broader offering
of laboratory sensors, which include
basic, advanced and research-grade
options to maximize measurement accuracy
and sensor lifetime in a range
of chemical process, pharmaceutical,
biomedical and other applications. An
intuitive interface guides users through
setup, calibration and measurement,
with easy-to-read prompts and results
displayed on its integrated screen. -
