Q: When
should I use an absolute pressure sensor rather than a gage
pressure sensor?
A: The
primary consideration concerns whether the atmosphere plays a
role in the application for which the pressure sensor is being
used. If any part of the application is exposed to the
atmosphere, such as an automotive emission system or in level
measurement in an open tank, a gage pressure sensor should be
used. But if the atmosphere has no effect on the application,
either type of pressure sensor can be used. However, when
measuring extremely high pressures, such as those found in
hydraulic applications, an absolute pressure sensor is typically
used. |

What's New
|
6 DF Position Sensor Aids Stability Control
The
HG1171 Series Inertial Measurement Unit (IMU) Sensor is a new
high-value product platform for the heavy duty vehicle (HDV)
segment. It utilizes MEMS (Micro Electromechanical Sensors)
technology to sense rate and acceleration information. MEMS-based
IMU technology has been successfully used in aerospace
applications for navigation and control (i.e. missiles, small
rockets); more recently, it has migrated to the automotive
industry for vehicle stability control. This new product offers
our customers in the commercial HDV segment enhanced
agricultural and construction vehicle performance.

Featured Product

Design Flexibility with 91MCE Series Limit Switches
The
small footprint, miniature package size, and range of user
options available with the 91MCE Series, one of our OEM set
global limit switches, increases ease of installation and design
flexibility in existing applications. The small package size can
be gang mounted for potential applications that need more than
two switch circuits. Both slow action and snap action circuitry
is available in addition to nine different actuator styles.
Direct Acting contacts are designed to ensure the Normally
Closed contact opens when actuated. The rugged metal housing is
sealed to IP67 and NEMA 1, 4, 12 and 13, making it often
suitable for potential outdoor applications. Potential
applications typically include aerial lifts, forklifts,
off-road, outdoor, material handling, and machine equipment.

Load Cells, Transducers Put Pistons to the Test
 Honeywell's
line of Sensotec load cells and displacement transducers are
employed by automotive system integrators to control equipment
where a press fit is required. Our Model 41 Precision Low
Profile Load Cell, with a wide load range and double diaphragm
design is designed to provide accurate feedback on the load
applied by the piston. Our stainless steel, non-rotating Model
PLVX AC-AC Ultra Precision Displacement Transducer is designed
to assure the part is correctly seated.

MICRO SWITCHTM TECHNOLOGY IN ACTION
MICRO SWITCHTM
technology lifts up the automatic gate to let you into the
airport parking lot and soon your baggage is entrusted to a
series of MICRO SWITCHTM
components in the baggage
handling equipment. Whew! You finally have a few minutes to
relax before your flight. You spy a vending machine with granola
bars, figuring that later on, you would like a mid-flight snack.
You drop your coins in and MICRO SWITCHTM
components activate the worm gear that moves your snack forward,
allowing it to drop into the pick up slot.
