DPT145 Multiparameter Transmitter for SF6 Gas
The Vaisala Multiparameter Transmitter DPT145 with the DILO DN20 connector.
Features/Benefits
▪
First transmitter to offer online
measurement of seven SF6
parameters in one unit
▪
Measured parameters: dew
point, pressure, temperature
▪
Calculated parameters: SF6
density, normalized pressure,
dew point in atmospheric
pressure, ppm
▪
Saves time and money across
the board, from investment and
installation to operation and
servicing
▪
More reliable assessment of the
condition of SF6 insulation due
to online measurement
▪
Long calibration interval of
years
The Vaisala Multiparameter
Transmitter DPT145 for SF6 Gas is a
unique innovation that enables online
measurement of dew point, pressure,
and temperature. It also calculates four
other values, including SF6 density.
The DPT145 is especially well suited for
integration into OEM systems.
Online Reliability
Online dew point measurement
combined with pressure
measurement provides an excellent
assessment of the condition of the
SF6 insulation. Sudden and minor
leakages are immediately detected
by the direct normalized pressure
measurement, while online dew
point measurement alerts the user to
moisture issues, which can weaken
the insulation properties of SF6
and cause rapid deterioration. With
the DPT145, it is also easy to build
a redundant solution for multiple
parameters.
Savings Across the Board
A single transmitter, instead of
several, saves time and money
across the board, from investment to
installation, operation and servicing.
Lower assembly costs, fewer cables
and connectors, minimized need for
on-site visits and field operations -
all these translate into cumulative
savings.
The long calibration interval results
in further savings.
Risk-Free, Greener
Solution
Online measurement enables gas
trends to be followed via a data
collection system, making monitoring
fast, risk-free, and accurate. Using
one instrument for monitoring seven
different parameters means also
fewer mechanical connections and
reduces the risk of leaks. Monitoring
is environmentally friendly because
there is no need for sampling - no SF6
gas is released into the atmosphere.
The Fruit of Experience
Vaisala has over 70 years of
extensive measurement experience
and knowledge. The DPT145 brings
together the proven DRYCAP
®
dew point sensor technology
and BAROCAP
®
pressure sensor
technology in one package, providing
an innovative and convenient
solution for monitoring SF6 gas.
