Maintenance-Related Products
Handheld device speeds
maintenance, startup efforts
The AMS Trex Device Communicator
(photo) uses the company's Power
the Loop technology. By removing
the need for an external power
supply, the device helps users work
more effectivey and perform faster
device configuration, on the bench
or in the field. This allows users to
perform device-configuration tasks
before power and I/O infrastructure
are in place, without the need for
the installation of the host system,
wiring, piping and other elements.
Technicians can simply connect the
communicator to a loose device to
power it up, speeding configuration
on the bench.- Emerson Automation

This vibration sensor
provides realtime data
Vibration fluctuations in water- and
wastewater-treatment systems often
provide an early indicator of problems
that cause equipment failure,
such as pump cavitation, unbalanced
fans and bad bearings. The
new Sensaphone Vibration Sensor
(photo) can be permanently mounted
on equipment such as pumps, motors,
generators and diesel engines
to continuously monitor vibration velocity
and detect unusual conditions.
The sensor provides constant, realtime
data, and sends an immediate
alert to designated personnel when
vibration levels fall out of a designated
range. It benefits from simple
two-wire 4-20-mA installation, is
easily configured, and requires no
special software, says the company.

Air bearings enable smooth
'nano-postitioning'
The A-62x PIglide Series of rotary air
bearings have no rolling or sliding elements,
and deliver frictionless, noncontact
motion. This is said to result
in negligible reversal error, and to
provide greater stability over straightness,
wobble, eccentricity and velocity
changes. Air bearings replace
mechanical contact by a thin film of
air. This air layer is completely frictionless,
eliminating breakaway stiction
and drag friction during operation. The
PIglide RM motorized rotary air bearing
stages offer a complete " nanopositioning
solution, " according to the
company. These rotary positioners
can handle speeds to 2,500 rpm, and
ensure extreme precision with radial
motion errors as low as ±50 nm, axial
runout as low as ±50 nm, and tilt errors
down to 0.3 arc-sec, and they
require no maintenance or lubrication,
says the company. - Physik Instruments

'Smart glasses' allow users
to support their machines
Remote Assist (photo) is an innovative
service concept that uses
Internet-enabled " smart glasses " to
enable the company's hotline technicians
to support its machines in
realtime. The technology enables
virtual communication between machine
operators and service technicians
via a wi-fi interface. Users who
require assistance to operate their
equipment, deal with fault conditions
and so on can now get virtual support
from this company. A camera
integrated to the glasses transfers
its perspective of the machine directly
to the company technician's
monitor, allowing the remote support
team to respond accordingly.
The glasses are also equipped with
a microphone and headphones for
audio communication with support
personnel at the company. - The

This high-performance
hydraulic oil is 'eco-friendly'
Panolin HLP Synth 32 is a biodegradeable
hydraulic oil that has been
engineered to meet demanding requirements
that are typical of today's
mechanical systems, such as power
density, higher working pressures,
motor speeds, oil-circulation cycles
and temperatures. The hydraulic fluid
