Permanent
lift magnet
Eriez Magnetics,
Erie, Pa. |
The new Safehold APL Series permanent lift magnet
for steel handling turns on and off automatically, offering increased safety
for operators and simplifying operation. The magnet is turned on and off
simply by lifting or lowering it with a crane, eliminating manual activation.
Magnets are intended for loading and unloading large steel sheets from burning
tables or anywhere that limits operator access. They can lift and transfer
steel and iron without slings, hooks, or cables. According to the manufacturer,
the magnets require fewer operators and, properly installed and operated,
provide greater safety than other mechanical material handling devices.

Intelligent
servo drive
Automotion Inc.,
Ann Arbor, Mich. |
The new ACS100 low-voltage, all-digital intelligent
servo drive uses a DSP-based design architecture and provides software-selectable
torque, velocity, or position mode operation. Sine wave commutation provides
smooth torque at low speeds, useful for robotic, direct drive, and linear
motor applications. An ac servo (flux vector) algorithm is said to provide
higher dynamic response and better noise immunity than servo amplifiers that
use sine wave feedback and analog multiplication techniques. Only a single
analog input is required for sine wave operation. The device measures 1 in.
by 5.35 in. by 3.32 in. and is rated at 5 amps continuous/15 amps peak. The
servo operates from a single 12 to 48 V dc power supply and can output over
700 watts of peak power for up to 60 milliseconds. It is designed for use
with dc, brushless dc, or brushless ac (vector control) servomotors and offers
both RS-232 and RS-485 serial communications. An optional CAN interface version
is also available.

High-
precision pressure transducers
Omega Engineering,
Stamford, Conn. |
The PX624 Series transducers combine photo-optical
sensors with state-of-the-art SMD electronic circuits. These features provide
accuracies of ±0.05 percent of span or better. For barometric and absolute
ranges up to 30 psia, exceptional long-term stability is ensured by the inclusion
of a "getter" material in the evacuated reference chamber. This material
acts as a sponge to absorb stray gas molecules as they are released from
the surface of the reference chamber. This ensures the integrity of the vacuum
reference over time. Each unit is furnished with a 20-point certificate of
calibration traceable to the National Institute of Standards and Technology.

Slides
PHD Inc.,
Fort Wayne, Ind. |
 The
company's Series SD/SE slides are now available with Rodlok, which is designed
to lock the piston rod while it is in a stationary position. When air pressure
is lost or removed from the device's port, the mechanism grips the rod, which
holds the attached load indefinitely. The slides have a slim profile and
are available in five sizes with travel lengths from ¼ in. to 28 in.
in ¼-in. increments. According to the company, they provide rugged,
precise linear motion with minimal deflection. Series SD slides are intended
to provide short travel in horizontal or vertical applications where slide
length and weight are critical; Series SE slides have more space between
the bushings and provide longer slide travel and better shaft stability.
Both series offer a choice of linear ball bushings or the firm's TC fluoropolymer
composite bushings, which have a thinner profile. Units are internally lubricated
and are said to be virtually impervious to contamination.

Flammable-
gas detector
Crowcon Detection Instruments,
Milford, Ohio |
Nimbus is a fixed infrared detector for flammable
gases in hazardous areas. According to the manufacturer, the device is rugged
and flameproof, and is expected to provide 10 years of maintenance-free
operation. The detector is designed to be integrated with existing gas detection
systems and can be used in conjunction with digital communication networks
or control systems such as the firm's gasmonitor unit. It can also be
incorporated into existing installations based on pellistor detector technology
using an optional pellistor mimic. The detector is compatible with Windows-based
and intrinsically safe handheld devices, allowing nonintrusive calibration
and fault diagnosis to be carried out in the field by one person. The optics
operate at up to 90 percent obscuration, with a dirty-optics warning light
activating at 75 percent obscuration. An external status light indicates
whether the unit is in normal function or fault, alerts users to rising gas
levels, and identifies 22 further conditions for simple diagnosis. The device
is small and lightweight and suitable for use in inaccessible areas, where
calibration using sample gas can be carried out via a remote gassing device
and an optical connector.

Relief/back
pressure valve
Plast-O-Matic Valves Inc.,
Cedar Grove, N.J. |
A high-flow-capacity, 3-in. NPT relief valve is
now available for corrosive and ultrapure liquids. Because of the many functions
the valve performs, it is also known as a back pressure regulator and bypass
valve. The Series RVTX is an angle-pattern valve constructed of Grade 1,
Type 1 PVC with a choice of Viton or EPDM elastomeric seals. The sensing
element is a solid PVC shaft (or stem) with a Teflon thrust washer to reduce
friction. The element works in conjunction with a large area rolling diaphragm
that enables the valve to open more rapidly, providing greater flow and
sensitivity to changing pressure. Relief/back pressure setting is adjustable
from 5 psi to 100 psi. When pressure drops below the set point, the valve
automatically reseats with a bubble-tight seal. Maximum flow rate is 200
gallons/minute.

Weld-quality monitoring system
Sensotec Inc., Weld Sensor Group,
Columbus, Ohio |
For monitoring resistance nut weld quality, a system
is available that consists of an industrial-duty linear displacement transducer
(LVDT) and the Model WM9100 weld meter. According to the manufacturer, this
system is effective in detecting missing or upside-down nuts or studs, measuring
weld "set-down" determining correct part dimension before welding, and monitoring
tool wear. The LVDT displacement sensor features ranges to fit all weld machines
and requires only two shoulder joints for monitoring. The meter provides
four programmable limits with relay contacts (ac or dc) that interface directly
to a weld controller, PLC, or quality system. Relays can also control light
posts to provide instant visual display of weld quality status. A serial
interface (RS-232 or RS-485) allows data to be downloaded directly into a
spreadsheet on a remote computer. These data are used to perform statistical
analysis and provide permanent traceability for each weld.

Monitor Technologies LLC,
Elburn, Ill. |
The Model FS rotary paddle bin indicator is an

whenever an electrical malfunction occurs. The indicator operates by sensing
the absence or presence of dry bulk solids in bins, silos, tanks, and hoppers.
When material is absent, the paddle rotates freely. The presence of material
impedes normal rotation and triggers an alarm condition. When the paddle
is stalled, a motor shut-off feature preserves motor life. Normal operation
resumes once material drops and the paddle rotates freely.
