Measurement distance and
temperature resolution for
plant maintenance
YOKOGAWA Electric Corporation has
launched the DTSX
®
3000 distributed
temperature sensor. With a one-metre
spatial resolution, this distributed
temperature sensor can measure the
temperature along fibre-optic cables
up to 50km in length, eight times the
distance possible with the company’s
previous model.
The DTSX3000 is suited to plant and
infrastructure maintenance applications
that necessitate the monitoring of
temperature over long distances or
across wide areas. Specific applications
include the detection of gas and liquid
leaks in tanks and other large production
facilities, and the detection of abnormal
heat levels in power lines.
Yokogawa currently sells the
DTSX
®
200 distributed temperature
sensor for use in applications that
include the monitoring of temperatures
in unconventional oil and gas wells,
the detection of leaks of high- or low-
temperature liquids and gases from
pipelines or tanks, and the detection
of abnormal heat build-up in coal and
wood chip conveyors.
In contrast to conventional techniques
that rely on the use of multiple
surveillance cameras or thermocouples
and resistance temperature detectors,
distributed temperature sensors can be
easily routed along the course of any
object that requires management.
Their temperature readings can
be displayed on a computer monitor,
allowing
maintenance
personnel
to quickly spot and respond to any
problems.
With its long measurement distance
and high temperature resolution, the
DTSX3000 meets the need for a single
device that is capable of detecting
minute temperature changes and
monitoring the temperature distribution
over a long distance or across a wide
area.
The development of shale gas fields
requires sensors that are capable
of detecting even minute changes
in the temperature distribution in a
bedrock formation during the hydraulic
fracturing process. In just ten minutes,
the DTSX3000 is capable of measuring
the distributed temperature along a 6km
fibre-optic cable, and it does this with
a top-level temperature resolution of
0.03°C, 20 times the precision possible
with conventional products.
The DTSX3000 can be used in a wide
range of applications, from the hydraulic
fracturing of bedrock formations to
the monitoring of
temperature levels
inside wells during
the gas recovery
process.
Yokogawa’s glob-
al network of 86
companies spans
56 countries. The
company’s
Euro-
pean headquarters
were founded in the Netherlands in
1982. Throughout Europe, Yokogawa
has its own sales, service and
engineering operations.
