South Col Barometer

Both in 2008 and in 2011 expedition a PTB330 barometer was installed at South Col. This sensor is manufactured by Vaisala company.

The operating principle on the basis of its work is that when the pressure changes, the silicon diaphragm bends and changes theheight of the vacuum gap in the sensor. This changes the capacitance of the sensor, which is measured and converted into a pressure reading.

Technical characteristics:

Range: 50 to 1100 hPa

Accuracy at +20 °C (serial output): ±0.30 hPa

Total accuracy at -40 to +60 °C (serial output): ±0.45

Accuracy for 50 to 1100 hPa (analog output): ±0.40 hPa at +20 °C; ±0.75 hPa between -40/+60

Temperature dependence : ±0.3 hPa

Long-term stability: ±0.2 hPa/year
