New Products
A portable gas monitor with an
extremely long service life
The BW Clip4 (photo) is a new fourgas,
portable monitor that can operate
continuously for two years
without the need to change sensors
or charge batteries. BW Clip4 monitors
significantly reduce maintenance
costs associated with fleets of portable
gas detectors by eliminating repair
work and the need to stock additional
sensors and spare units. Because it is
always on, the BW Clip4 helps drive
safety compliance by assuring that
workers wearing the device are protected.
Using non-dispersive infrared
(NDIR) technology, the BW Clip4 reportedly
consumes 1,000 times less
battery power than a catalytic bead
(pellistor) sensor, the traditional technology
used to detect flammable
gases in a portable device. Other features
include the following: simultaneous
monitoring of H2S, CO, O2 and
combustibles; realtime display for instant
gas readings, even in non-alarm
conditions; and internal test functions
that alert users when the unit should
be replaced. - Honeywell Analytics,

New chemical solution
for dust suppression
Sentinel dust suppressant (photo) is a
proprietary chemical that is designed
to adhere the finest silica particles to
larger particles to prevent the fines
from becoming airborne. The chemical
is sprayed onto sand grains and
adheres to the small dust particles,
effectively trapping them. Silica dust
inhalation can be hazardous to the
health of workers, and recent OSHA
ruling has limited the permissible exposure
limit (PEL) for respirable silica
dust in order to have a safer work
environment. This liquid dust-control
agent is effective on sands of all
mesh size, including 100-mesh sand.
The mobility of the application system
allows it to be applied at any site
without impacting normal operations,
and the robustness of the chemical
helps it maintain its performance
after multiple transfer points, says
the manufacturer. - Hexion Inc.,

Extremely long submersible
canned-motor pumps
As a replacement for conventional
submersible pumps, this company
supplied two eight-stage,
sealless
canned-motor pumps of the TCAM
30/4+4 Series to a Swiss fine-chemicals
company as an alternative to
conventionally
sealed pumps. The
supplied submersible pumps (photo)
are the longest pumps this company
has ever produced, with an immersion
depth of more than 15 m,
and a pump shaft of only 1 m. The
submersible pumps, in tandem design,
convey the medium (ammonia)
at a temperature of -33°C. The
delivery head is 260 m at a flowrate
of 12 m³/h. The pump units are designed
for a nominal pressure of 40
bars and are suitable for operation
with frequency converters (30-60
Hz). - Hermetic-Pumpen GmbH,

This vibrating-fork level detector
has wired HART connectivity
Rosemount 2140 (photo) is said to be
the world's first wired HART vibratingfork
level detector. The Rosemount
2140 detects level in applications
with high temperatures and harsh
conditions that are unsuitable for
other level-monitoring devices. It is
easy to install and maintain, as there
are no moving parts. The device is
virtually unaffected by flow, bubbles,
turbulence, foam, vibration, sediments
content, coating, liquid properties
and product variations, according
to the manufacturer. It can be used to
monitor not only liquids, but also liquid-to-sand
interfaces, which enables
the detection of buildup of sand or
sludge deposits in a tank. For safetycritical
applications, a dedicated version
of the Rosemount 2140 certified
to IEC61508 is available. For installations
within safety instrumented systems
(SIS), a fully integrated remote
proof-testing capability eliminates the
need to access the top of the vessel
for extracting the device from the process.
This saves time and increases
process availability, worker safety and
efficiency. - Emerson Automation
