3-in-1 Dewpoint, Pressure, Temperature Transmitter for SF6 Gas DPT145

The Vaisala Dewpoint, Pressure and Temperature 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.

- 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

What is Dewpoint?

Dew point is the temperature to which air must be cooled for water vapor in it to condense into dew or frost. At any temperature there is a maximum amount of water vapor that the air can hold. This maximum amount is called water vapor saturation pressure. Addition of more water vapor results in condensation.

Monitor Dewpoint, Pressure and Temperature in one instrument

Vaisala Dewpoint, Pressure and Temperature 3-in-1 Transmitter DPT145 is an online dew point transmitter, pressure transmitter and temperature transmitter, 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 SF
6 and cause rapid deterioration.

With DPT145, it is also easy to build a redundant solution for multiple parameters
