This dosing system reduces
exposure to materials
The Sure Dose portable dosing system
(photo) allows for safer dosing of materials
from smaller feed tanks to larger
batch or mix tanks. Since the system
requires no lifting or suspension of the
drum, operator exposure to the materials
being transferred is reduced. Utilizing
differential-pressure technology,
the closed system allows dosing of
most liquids, such as biocides, acids
and caustics. Since the Sure Dose
unit does not utilize delicate load cells,
it does not require the supply drum to
be elevated, and it can be placed on
the floor while dispensing the material.
Operators can dispense liquids using
various units of measure, such as level,
volume or mass, via the user-friendly
interface. To ensure compatibility, the
dosing system is available with different
materials of construction. Available
options include an automated control
system, along with LED indicator
lights for unit status, sensor extension
cables and data-logging capabilities.

Android devices for use
in hazardous locations
In addition to the Agile X Windowsbased
10.1-in. tablet PC system,
this company now offers two smaller
Android devices that are certified for
hazardous areas. The Lumen X4 is
a 4.3-in. industrial mobile computer,
and the Lumen X7 is a 7-in. industrial
tablet for use in harsh environments.
The devices survive being
dropped or immersed in water, and
are resistant to extreme temperatures.
The devices also have nearfield
communication (NFC), Bluetooth
3.0 and two powerful cameras.
The Lumen X4 can be optionally
equipped with a scanner for recording
barcodes. - Bartec GmbH, Bad

Modular drying systems for
extremely dry process air
This company's Dry-Tec product line
contains modular systems for use with
extremely dry process air, enabling processes
to achieve dewpoint temperatures
as low as -65ºC, at volumetric
32
flowrates from 500 to 7,500 m3/h. The
Dry-Tec product line contains a basic
sorption module that is used for adsorption
and desorption within the system,
as well as the precooler module CoolTec
V and the aftercooler module CoolTec
N. The precooler and aftercooler
modules can optionally be equipped
with various filtration elements. In addition
to achieving low relative humidity,
a nearly particle-free process airflow at
the entry and exit of the module system
can be provided. Due to their compact
design and the modular assembly of
the overall system, the units can be
easily transported and introduced into
existing production facilities. All modular
Dry-Tec systems are available with
stainless-steel housing. - ULT AG,

Determine solubility in a variety
of materials with this tool
The Phase Monitor II (photo) determines
the solubility of various compounds
and mixtures in supercritical
and high-pressure fluids. It provides
direct, visual observation of materials
under conditions precisely controlled
by the researcher. Experiments may
be performed in liquids, supercritical
CO2 or other liquefied gases. The effect
of co-solvents on the solubility of
compounds of interest may be investigated
as well. The Phase Monitor II
allows the user direct observation of
the dissolution, precipitation and crystallization
of compounds over a wide
range of pressures and temperatures.
Advanced studies may be done to determine
melting-point depressions and
the degree of polymer swelling in CO2
or traditional solvents. Experiments
can be performed at pressures up to
10,000 psi and from ambient temperature
to 150ºC. - Supercritical Fluid

Precisely position movable
tools with this encoder
The CVM42H CANopen multi-turn
absolute encoder (photo) features
stainless-steel housing, flange and
shaft, and utilizes magnetic sampling
to deliver 24-bit resolution position
values. These compact rotary encoders
excel in harsh environments with
high mechanical stresses, and can
