Process
sample filtration
Parker Hannifin Corp., Haverhill, Mass. |
Fast loop Balston sample filters offer real-time sampling with high-efficiency
filtration. The unique flow pattern continuously flushes the filter cartridge
carrying the contaminants back out to the process stream, thus maximizing
the filter cartridge life. Axial velocity flushes contaminants through the
filter housing back to the process stream. The sample stream passes through
the filter cartridge wall with low flow and radial velocity. The clean side
of the sample filter system has very low volume, which minimizes lag time.
The cartridges come in efficiencies from 100 micrometers to 0.01mm.

Sensor system
PCB Piezotronics Inc., Depew, N.Y. |
The Torkdisc rotary torque sensor system
is a compact, inline unit, especially designed for automotive powertrain
dynamometers and other torque measurement applications that require a robust
torque transducer where axial space is at a premium. The Torkdisc features
a field proven telemetry system that consists of an onboard electronic module
that converts torque signals into a high-speed digital representation. Once
in digital form, this data is transmitted to a non-contacting pickup loop,
with no risk of noise or data corruption. A remote receiver unit converts
the digital data to a high-level analog output voltage, frequency output,
and a serial digital output. Typical applications include dynamometer testing
of gasoline and diesel engines, transmissions, transfer cases, and differentials.

Dynamom- eter tables
Magtrol Inc., Buffalo, N.Y. |
The company is now offering eight standard
dynamometer tables. Each has been specifically designed to accommodate one
of Magtrol's hysteresis/engine or eddy-current/powder brake dynamometers,
and can be customized to meet the needs of most testing applications. Besides
strength, these corrosion-resistant tables offer two key benefits, por-
tability and versatility, according to the manufacturer. Many dyna- mometers
are very difficult to move once fixed to a stationary workbench. Magtrol
dynamometer tables eliminate this shortcoming, according to the company.
These tables are useful for moving dynamometers to alternate testing stations
because the stand is manufactured out of lightweight aluminum with casters
for smooth mobility. The company can modify its basic table design to accommodate
as many as three
dynamometers.

Production vises
Jergens Inc., Cleveland, Ohio |
BallLock base production vises are
intended to provide quick-change fixturing solutions in two ways: Jaw changeovers
take less than a minute and the BallLock mounting system built in the vise's
base permits one-minute changeover of vises. The vise's base also has an
interlocking jigsaw pattern, which permits multiple vises to nest closely
together, maximizing workpiece density on a fixture. By combining these
features, the Jergens production vise provides a quick change replacement
to conventional dedicated fixtures as well as to old-style vises. All jaws,
which come in 4-in. and 6-in. widths, are fully machinable and reversible,
providing more flexibility for each jaw set.

Sight feed valves
Oil-Rite Corp., Manitowoc, Wis. |
These sight feed valves are suitable for pressure or gravity lubricating
systems, where small quantities of liquid are to be drop fed. The sight
feed valves are applicable to a variety of industries, such as chemical,
mining, paper, agricultural, marine, woodworking, and textile. The valves
are used to lubricate typical equipment like pumps, compressors, machine
tools, bearings, seals, punch presses, and roller chains. Construction uses
a plated steel body or aluminum alloy. The sight viewing glass is held between
two gaskets and a needle valve regulates liquid flow. Fine adjustments can
be made and the sight chamber permits observation of the liquid. The friction
lock retains the setting. These valves are suitable for operation on pressure,
gravity, or vacuum service. They come in angle, cross, inverted angle, or
straight patterns with 1/8, 1/4, 1/2, 3/4, and 1 in. NPT.

Circulation heater
Watlow, St. Louis, Mo. |
The Cast-X Series 2000 circulation
heater provides fluid heating in a compact package where cleanliness, temperature
accuracy, and high pressure are needed. Applications include solvent heating,
heat transfer systems, ultrapure gas heating, food and beverage heating,
paint heating, two-part foam and urethane heating, and DI water heating.
The heater consists of a helical coiled tube that is cast into an aluminum
body with tubular elements. The aluminum body serves as the heat transfer
medium between the tubular element and the coiled tube that the fluid being
heated passes through. According to the company, the construction of the
heater allows it to be used where viscous or thermally sensitive materials
are being heated, such as paints and resins, and flammable materials like
fuels, solvents, and coatings. The aluminum mass acts as a Òthermal
flywheelÓ and ensures accurate temperature control of the fluid to
prevent degradation.

Force sensors
PCB Piezotronics Inc., Depew, N.Y. |
High-sensitivity miniature Series 209C
quartz piezoelectric force sensors from the force/torque division of the
company measure dynamic compression and tensile forces in a variety of biomedical
tissue product testing applications. Sensors feature ICP voltage output,
and have a high sensitivity of 2,200 mV/lb. (500 mV/N) at a force range
of 2.2 lbs. (10 N) in compression and 1 lb. (4.5 N) in tension. ICP force
sensors contain built-in microelectronics to convert the high impedance
charge to a low impedance voltage, which eliminates the noise associated
with charge amplifiers and the required high impedance cables. Biomedical
applications include dynamic testing of muscle fiber, cartilage, bone, and
hair specimens. Product testing applications include spring force and hysteresis,
electrical contact and relay actuation forces, computer keyboard finger
force, and touch screen push force.

Shrink film wrap
Protective Packaging Corp., Carrollton, Texas |
A new outdoor-grade shrink film product
contains corrosion inhibitors as well as UV protection. Called Protect Wrap,
it was conceived for applications requiring outdoor storage or transit of
very large pieces of equipment, such as planes, tanks, compressors, electrical
apparatus, generators, road equipment, cranes, etc. It is said to keep dust,
bugs, and bird droppings off a protected product, as well as keep corrosion
from happening without cracking or becoming brittle from sun exposure. The
manufacturer suggests the product as a more cost-efficient alternative to
tarpaulins. This inflammable product comes in thicknesses of 4 to 10 mils,
and can be delivered in rolls up to 40 ft. wide and 200 ft. long. Larger
coverage areas can be protected by overlapping material and bonding with
a heat gun. When heated, the two materials will stick to each other, not
to the product being wrapped.

Relay products
AutomationDirect, Cumming, Ga. |
The AD-70-STM-1 socket timing module
works with voltages from 24 to 240 V ac/dc and converts either the 783 or
784 Series relays to time delay relays. For simple timing applications,
using the new timing module and a low-cost relay can be more cost-effective
than an integrated timer, according to the company. This module also allows
the user to replace the relay without harm to the timing circuit, reducing
maintenance costs. The socket timing module has eight dipswitch selectable
time scales ranging from 0.1 second to 10 days. These scales can be fine
adjusted using the built-in potentiometer. The timing module has both transient
and reverse polarity protection. With an operating temperature range of
-25° to 55°C, the AD-70-STM-1 can be used in almost any application.
The 784-4C-SKT-1 DIN rail mountable socket ($3) works with this module and
with the 784 Series cube relays.
