pressure-seal bonnet provides ready
access for servicing with no welds to
cut or seal rings or gaskets to replace.
The body-to-bonnet joint integrity is
maintained through countless thermal
cycles. The durable, single-piece
stainless-steel gland contributes
to
the longevity of the valve. - Conval,

Interpret clamp load within
bolts, and monitor remotely
Knowing the tension of critical joints
is essential to safety, performance
and maximizing uptime. SPC4 loadindicating
technology (photo) makes it
possible to measure the actual tension
in a fastener, not just the preload that
is being applied by torque or tension
tools. By using SPC4 and any one of
its specially designed interchangeable
readers, technicians can quickly and
easily gage tension and even have the
option of remotely monitoring fastener
tension within SPC4 bolted joints.
SPC4 is ASTM F2482 compliant, and
accurately measures direct tension in
the fastener within ±5%. It provides
absolute, realtime knowledge of fastener
tension and performance - from
installation through the full fastener life.
SPC4 measures the stretch of the
bolt (in other words, the bolt tension),
directly from the fastener. Because
stretch is the force that creates clamp
load, this capability makes SPC4 the
most accurate method available to
monitor the clamp load of critical joints,
says the company. - Valley Forge &

Two new point-level instruments
recently introduced
The Liquiphant FTL51B and FTL41

capabilities,
level
instruments
(photo) were recently
launched. The FTL51B features Industry
4.0 and industrial internet of
things
including
access via wireless Bluetooth technology,
automatic proof tests and
verification, and easy commissioning
via a mobile device. In addition, operational
clarity is provided by a highvisibility
LED. The Liquiphant FTL51B
can be used in storage tanks, containers
and pipes for point-level de22
tection
of all types of liquids. The
instrument's vibronic sensor is not affected
by changing media properties,
flow, turbulence, gas bubbles, foam,
vibration or buildup. The instrument
works in process temperatures of
-58 to 302°F and pressures up to
1,450 psi. It can be used in SIL2 and
SIL3 hazardous locations, and has
built-in automatic maintenance and
verification functions. The generalpurpose
FTL41 works at lower pressures,
up to 580 psi, and with a narrower
temperature range of -40 to
302°F. Both perform proof tests, with
the FTL51B meeting SIL and WHG
(Water Resources Act) requirements.
The proof test can be activated remotely
at a control system, or locally
via a magnet or pushbutton test. The
proof test diagnoses the sensor for
corrosion and buildup, and ensures
that the entire instrument is operating
properly. - Endress+Hauser Group,

These luminaires have
a DALI interface
This company has expanded its product
range, adding modern explosionprotected
lighting systems equipped
with Digital Addressable Lighting Interface
(DALl; photo). The new EXLUX
variants correspond to the DALI standard
according to IEC 62386 and are
specifically designed for consistent
lighting management for general and
emergency lighting, even up to Zone 1
explosion protection. As well as safety
and emergency lighting, the range includes
durable, energy-efficient linear
luminaires that can be installed as
ceiling, pendant or pole-mounted light
fittings. These luminaires, from the
EXLUX 6002/4, 6402/4, 6009/4 and
6409/4 ranges, are designed to function
for over 100,000 operating hours
at a maximum ambient temperature
of 60°C. Thanks to the use of bidirectional
DALI communication, around
200 programmable commands can
be configured, allowing operators to
set different intensity values and dimming
behavior for individual light fittings
or luminaire groups. - R. Stahl,
Waldenburg, Germany
