patible with industry-standard, threewire,
Pt-100 sensors and accepts threewire
screw terminal attachments.
Battery life is up to 10 months, or up to
4 years with the L Version. Communication
range is up to 500 ft and can be
extended with the use of repeaters. -

Mercury-free alternative for calibration
is also more rugged
On March 1, 2011, the National Institute
of Standards and Technology
(NIST) stopped providing calibration
services for mercury-filled thermometers,
which have been a fixture for
calibrating temperature sensors in
the chemical process industries. The
1551A Stik thermometer (photo) provides
a robust alternative, featuring
a thin-film RTD sensor that provides
repeatable accuracy of ±0.05°C (0.09
°F) over its full range from -50 to 160
°C (-58 to 320 °F). A stainless-steel
Turck
Fluke Corp.
sheath protects the sensor, making
it much more rugged than the glass
stems of mercury thermometers, so it
is much better suited for challenging
industrial environments. In addition,
Stik thermometers are intrinsically
safe (ATEX- and IECEx-certified),
so they can be used in environments
where potentially explosive gases are
present. - Fluke Corp., Everett, Wash.

Temperature transmitter incorporates
advanced diagnostics
The STT250 temperature transmitter
now includes advanced diagnostics
for proactively managing the health
of the device, thereby preventing failures
before they occur and reducing
plant downtime due to unscheduled
repairs. Maintenance teams can also
use the advanced diagnostic information
stored on the transmitter to alPROTECT
