Monitor cell growth
with this sensor
(NIR)
The OUSBT66 sensor (photo) is
designed for cell-density measurements
using near-infrared
technology.
absorbance
The non-intrusive, hygienic sensor
can monitor cell growth in life
processes,
science
fermentation
biomass measurement and algae
biofuel applications. The sensor
allows rapid and accurate measurement
of cell growth activity
in cultures and can be used for
realtime,
in-situ
optimization
and
cell-production
to
identify
the end-of-log-growth phase
and the achievement of stationary
growth. The body of
the OUSBT66 sensor is constructed
of
316L stainless
steel and uses proven optical sensor
technology, the company says.
Using an LED light source, the
sensor filters the light to 880 nm,
the detection of which is correlated
to the density of cells in the
process. - Endress + Hauser, Greenwood,

Position this safety light
curtain anywhere
The deTec4 Core safety light curtain
(photo) is a guard-only safety light
curtain with this company's QuickFix
and Flexfix brackets that can be positioned
in any location on machinery
housing without causing blind zones.
The product is designed for hazardous
point protection and single-sided
access protection, and can be used in
machine-building and storage and
conveyer applications. With a unique,
built-in automatic range detection of
10 m, the deTec4 Core is able to automatically
determine distance to
the sender, which eliminates manual
setup of the sensing distance, the company
says. The deTec4 Core is available
in heights from 300 to 2,100 mm,
with 14- and 30-mm resolutions. -

Get touchscreen navigation
with this viscometer
The DV2T viscometer (photo) is now
available with touchscreen technology,
which creates an advanced user experience,
the company says. The 5-in.,
full-color display guides users through
test creation and data gathering for
fast and easy viscosity measurements.
The DV2T also offers powerful new
programming capabilities and results
analysis, including data analysis
and quality-control limits with
alarms. Program generator software
can create multi-step test protocols. -

This valve handles
very high pressures
This company's CV Series valves
(photo) are capable of continuous operation
at pressures up to 20,000 psi.
The valve is available as either an onoff
position model or a three-way, fourposition
model. In addition to high
pressures, the patented valve design
can be used in high-temperature applications
and with corrosive fluids. The
CV Series valves are pneumatically
operated via a set of small, low-voltage

pilot valves. The CV valves maintain
a constant internal fluid volume and
do not trap any fluid within the valve
body when switched, the company
says. - Vindum Engineering Inc., San

These gas-sampling fi lters
allow particle-free samples
All-metal inertial gas-sampling (IGS)
filters (photo) from this company allow
the collection of particle-free samples
from virtually any gas stream. Even
heavily contaminated gas streams
and extreme-temperature samples
can be handled by the durable filters,
the company says. Typical applications
include gas sampling in stack
testing, utility coal pulverizers, lime
or cement kilns, fluid catalytic crackers,
coking-oven offgas atmospheres
and general emissions-control monitoring.
The IGS filters feature a crossflow
design that keeps most particles
in the gas stream greatly reducing
obstruction of the filter element. The
company's porous-metal filter media
is durable and can be used in highly
corrosive environments. - Mott Corp.,
