Wireless capability simplifi es
level and interface monitoring
The Rosemount 3308 Wireless
Guided-Wave-Radar (GWR) transmitter
(photo) is designed for continuous
level and interface monitoring
in remote locations where
installing cable is costly or impractical.
GWR transmitters are used
for process level measurement in
vessels and storage tanks in refineries,
oil fields, offshore petroleum
platforms, chemical and industrial
plants. Top-mounted for direct
level and interface measurement,
the Rosemount 3308 is virtually
unaffected by changing process
conditions, such as density, conductivity,
temperature and pressure.
The transmitter has no moving
parts, thus minimizing calibration
and maintenance needs. Costs are
further reduced when compared to

Use this explosion-proof LED
lamp in hazardous locations
The EHL-LED-230X24LV-300 Explosion-Proof
Hand Lamp (photo)
is designed for rugged use with an
aluminum lamp body and globe
guard, impact-resistant bulb cover,
and rubber housing bumpers for
added protection. The high-output
LED lamp runs on low-voltage 12-
or 24-Volt current supplied by an
inline transformer and offers international
230-V d.c. operating capability.
The risk of accidental burns
is greatly reduced due to the lamp's
cooler operation when compared to
typical
incandescent
bulbs.
This
lamp is also impervious to shattering
and blowout when dropped. The
lamp includes a long-reaching 300ft
cord, which comes without an attached
plug, allowing operators to
match plugs to the design of local
outlets. - Larson Electronics, LLC.,

Use this exchanger for heat
recovery with corrosive media
The Diabon S15 plate heat exchanger
(photo) provides efficient heat transfer in a
corrosion-resistant environment, suitable
for use with corrosive media up to 200°C.
It is constructed from Diabon graphite
material, which is a dense, synthetic resinimpregnated
graphite with a fine pore
structure. Combining high turbulence
and countercurrent flow, the Diabon S15
maximizes heat recovery, yielding energy
savings. Designed to reduce maintenance,
the exchanger features accessible plates
and a special plate pattern that reduces
fouling. The S15 is larger than other heat
exchanger types, with the potential to replace
several shell-and-tube or block exchangers.

These hose assemblies offer
greater vacuum resistance
This company's heavy-wall convoluted
hose assemblies (photo) can handle
vacuum applications in temperatures
up to 500°F. These hoses' thicker PTFE
walls provide improved vacuum resistance
at high temperatures as well as
greater kink resistance and reduced
permeation. The PTFE core also serves
to reduce friction, effectively minimizing
pressure drops and deposits. Manufactured
in sizes from ½- to 4-in. I.D.,
stainless-steel or polypropylene braids
are available. Additional accessories
include fire sleeves, spring guards,
heat-shrink for color-coding and static
dissipative assemblies. - Parker Hannifin
