Collet
chucks
Command Tooling Systems, Ramsey, Minn. |
A new line of DR (ER) 32 "Shorty"
collet chucks is for tool shank diameters from 0.079 to 0.787 in. The chucks
have an extremely short projection, so users can maximize workpiece size.
According to the company, tests have shown an increase in machining parameters
(feeds and speeds) of almost three times over conventional collet chucks.
The "Shorty" collet chucks are available in 40 V and 50 V
models. The units feature a nearly flush collet nut that virtually eliminates
tool overhang, improving accuracy while enhancing tool rigidity. Collet
pockets are concentric to the spindle taper to 0.002 in., precisely placing
the tool on the spindle centerline. Taper tolerances are AT3 or better.
These short collet chucks are particularly suited to small vertical machining
centers and multiplex turning machines.

Lift table
Pentalift Equipment Corp., Buffalo, N.Y. |
Pentalift's new lift table is
equipped with a powered deck extension that moves laterally. The 3,000-lb.-capacity
table has a 60 x 84 in. platform with a 50-in. vertical lift. A 48 x 22
in. deck, stored within the platform, can be extended hydraulically to provide
a walk-over bridge for use by maintenance personnel servicing machinery.
Nonslip rubber matting on both the platform and extension deck provides
better footing, while a fail-safe interlocking design prevents the lift
table from raising or lowering unless the extension deck is in a fully retracted
position. Accordion bellows around the lifting mechanism minimizes debris
entry under the lift table.

Pressure transducer
Setra Systems Inc., Boxborough, Mass. |
Setra's Model 595 is a digitally
compensated submersible pressure transducer. Its integral specific gravity
compensation gives a true level reading even when subjected to media temperature
changes over the range of 23°F to 113°F (-5°C to 45°C).
This unit is useful for groundwater and sewer flow monitoring, storm water
studies, stream flow monitoring, infiltration/inflow studies, pump tests,
irrigation, flood warning, sea level, tide, and wave monitoring applications.
Model 595 has 318 stainless steel wetted parts, which makes it resistant
to corrosion and good for long-term submersible operation. Its custom-designed
hermetic header means that water cannot enter the transducer even if the
cable sheath is damaged. Rapid venting is achieved through the large bore
vent tube connected directly to the back of the sensor. The sensor is resistant
to the effects of humidity, which can cause condensation.

parallel belt and pulley drive, and in-line planetary gearing. Removable
and adjustable mounting features enable the user to mount the I Series in
nearly any machine configuration. Typical applications for the linear actuator
include automated assembly, material handling, pressing, pick-and-place,
gantry, stage positioning, forming, and dampers. The actuator come in 2-,
3-, and 4-in. frame sizes with stroke lengths from 2 to 18 in.

General- purpose
transducers
Omega Engineering Inc., Stamford, Conn.
|
Economically priced but with many features,
the new IP211/EP211 Series from Omega consists of electropneumatic transducers
that decrease supply pressure, converting it to regulated output pressure
in direct proportion to an electrical input signal. The IP211/EP211 Series
accepts a range of supply pressures, from 3 psig (0.2 bar) above the maximum
output to 100 psig (6.9 bar). An integral pneumatic volume booster provides
high-flow capacity up to 12 scfm. Factory-calibrated for direct-acting operation,
these transducers are field reversible. If used in reverse-acting mode,
they require recalibration after the polarity of the signal leads is reversed.
The series incorporates general-purpose, FM intrinsically safe and CSA intrinsically
safe models, all of which mount at any angle. Small and lightweight, IP211/EP211
models can be pipe, panel, or bracket mounted. Price starts at $285.

Linear actuators
Warner Electric, South Beloit, Ill. |
A-Track Series linear actuators incorporates
many new design features, including a round, ground ball nut, a motor shaft
supported by bearings rather than bushings, and limit switch and potentiometer
options. A-Track Series actuators include four models that are available
to meet a variety of application requirements. According to the company,
the round, ground ball nut makes the transition of the ball bearings much
more consistent as opposed to a tapped square unit and gives it better life
characteristics, as does the use of bearings to support the motor shaft
as compared to bushings. With their compact size, A-Track actuators can
be located in confined areas, yet will move loads from 25 to 1,330 lbs.
Weatherproofing makes these actuators good for use on outdoor equipment.

Vibration switch
Hardy Instruments, San Diego, Calif. |
The Hardy vibration switch provides
reliable machine production in a compact package. This low-cost, self-contained
monitoring system can be mounted to any location on rotating or reciprocating
equipment, and provides alarm or shutdown if excessive vibration levels
are reached. No vibration expertise is required to install and set up the
vibration switch, as all sensing and electronic components along with an
LED alarm display are included. The switch also incorporates an integral
relay to provide fail-safe operation with both normally open and normally
closed contacts in the most rugged installations. An optional 4-20 mA analog
output allows you to trend vibration levels on equipment as part of predictive
maintenance efforts.

Integrated monitoring system
Emerson Process Management, Chanhassen, Minn. |
The Rosemount 753R with iTraX is a Web-based monitoring system for inventory
management that integrates smart sensors, communications, and self-contained
power into a single packaged solution. The new monitoring system includes
intelligent Rosemount 753R indicators that provide reliable wireless communication
of measurement data, alerts, and device health status through established
cellular networks. The data is accessed via the secure iTraX Web interface.
The 753R with iTraX is the first of many technologies in Emerson's
Smart Wireless portfolio that improve access to critical information that
was previously inaccessible. The Rosemount 753R with iTraX is useful for
vendor managed inventory and remote inventory monitoring applications, where
avoiding customer tank outages is critical to distributors of industrial
gases, specialty chemicals, and fuel. The new smart monitoring system mitigates
tank outages and reduces the logging of thousands of miles from unnecessary
bulk product deliveries.

Temper- ature trans- mitter
Omega Engineering Inc., Stamford, Conn. |
The OM-CP-RFTC4000A is an easy-to-use,
portable, compact, battery-powered, stand-alone thermocouple-based temperature
transmitter device. According to the company, it is a step forward in both
size and performance. When enabled, the wireless transmitter will transmit
readings back to the host computer where the data can be analyzed in real
time. For added security, the readings are logged to the device memory.
The slide switch allows the transmitter to be turned on or off without affecting
the operation of the device. Data is received at the PC using the OM-CP-RFC101A
receiver that attaches directly to the serial port. Received data is time
and date stamped and stored directly in your PC. Windows software converts
your PC into a real-time strip chart recorder. Data can be printed in graphical
or tabular format and can also be exported to a text or Microsoft Excel
file. The basic unit costs $249.

Chemical fastener
adhesives
Nylok Corp., Macomb, Mich. |
Because they have longer shelf life
and high structural strength, fast-curing pre-applied Precote chemical fastener
adhesives offer vibration-resistant locking and sealing properties for a
range of applications, according to the manufacturer. The company says that
Precote is the industry's only duo-microencapsulated thread adhesive
and therefore will not harden prematurely because of chemical reactions
of moisture or solvent penetration. The adhesives are suitable for automotive,
aerospace, electronics, telecommunications, and other high-technology industries
since they eliminate the need for additional locking devices.
