teach-mode sensor combines window
thresholds on both target distance and
target reflected intensity, and can now
detect clear objects without requiring
a retro-reflector. The Q4X detects distance
changes as small as 1 mm, and
covers a range from 25 to 300 mm.
The sensor is suitable for difficult distance-based
sensing applications, as
it can detect objects regardless of target
surface reflectivity, including black
foam on black plastic, black rubber in
front of metal and multicolor packaging.
With the dual-teach mode, the
sensor can now detect small changes
in reflected intensity for targets inside
the distance threshold. - Banner

A TDL gas analyzer designed
specifically for ammonia
The Servotough MiniLaser Ammonia
(photo) is said to be the world's
smallest cross-stack tunable-diode
laser (TDL) gas analyzer, and the only
TDL analyzer specifically optimized
for ammonia gas measurement. Optimized
for the fast, accurate and responsive
measurement of ammonia
in hot or hazardous conditions, the
Servotough MiniLaser Ammonia is
particularly suitable for ammonia slippage
applications in coal-fired power
plants. The MiniLaser's compact size
and dramatically reduced footprint
offer installation flexibility. A built-in
display eliminates the need to use
a laptop for configuration and diagnostics.
The MiniLaser Ammonia also
includes a new purge design, which
significantly reduces nitrogen and
air purge costs. - Servomex Group

Ironless motors provide smooth
motion and a high velocity range
The compact V-551 motorized lineartranslation
stage comes equipped
with an integrated absolute-measuring
encoder with a resolution of 2 nm.
High velocity (up to 500 mm/s) and
quick acceleration are provided by a
newly developed ironless magnetic
linear motor, resulting in high accuracy
and smooth motion. Precisioncrossed
roller bearings with anti-creep
cage assist provide accurate guiding.
The ironless non-cogging linear
motors provide very smooth motion,
and a high dynamic velocity range,
along with rapid acceleration. They
are suitable for applications where
high or extremely constant velocity is
required, such as in optics inspection,
metrology, photonics and interferometry.

Energy-efficient induction
motors for use with VFDs
The Large AC-GPM line of energyefficient
foot-mounted induction motors
(photo) includes custom models
ranging from 250 to 1,500 hp. The
GPM product line fits various industrial
applications where high torque is
required, including pumps, fans, conveyors
and compressors. Stock GPM
motor features include all cast-iron
construction, drive-end slinger, insulated
opposite drive-end bearings,
space heaters, and a ground lug in
the conduit box. The entire product
line is suitable for use with VFDs. -

Expanded compatibility for
this boiler-control system
This company has expanded its patented
Temp-a-Trim control system
(photo) so that it is compatible for installation
on any brand of commercial
or industrial boiler. The Temp-a-Trim
system is designed to deliver fuel
savings of up to 3% and electrical
savings of up to 30% in boilers, says
the company. Temp-A-Trim works by
precisely correcting for air density,
as the combustion air temperature
changes to automatically optimize
combustion efficiency. A built-in VFD
adjusts the fan speed based on incoming
air temperature to create a
constant airflow for combustion, assuring
that the burner is always operating
at its maximum efficiency.
