VAISALA DPT145 SF6 Gas Multiparameter Transmitter Online Measurement of dew point, pressure, and temperature
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.
Features
Measured parameters: dew point, pressure, temperature
Calculated parameters: SF6 density, normalized pressure, dew point in atmospheric pressure, ppm
Digital output RS-485 with MODBUS
Specifications
• The 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
• More reliable assessment of the
condition of SF6 insulation due to
online measurement
• Digital output: RS-485 with
Modbusâ
• Long calibration interval of years
Key Benefits
Risk-free, greener solution
Enables gas trends to be followed via a data collection system. Monitoring is environmentally friendly because there is no need for sampling - no SF6 gas is released into the atmosphere.
Cost-effective
Saves time and money across the board, from investment and installation to operation and servicing.
Easy maintenance
Long calibration interval of years
Online reliability
Online dew point measurement
combined with pressure measurement
provides an excellent assessment of
the condition of 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 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. DPT145 brings together the
proven DRYCAPâ dew point sensor
technology and BAROCAPâ pressure
sensor technology in one package,
providing an innovative and convenient
solution for monitoring SF6 gas.
