Pressure transmitter PTB110
The PTB110 pressure transmitter was developed to measure the exact air pressure at ambient temperature, as well as for general monitoring of the ambient pressure in a wide temperature range.
Vaisala BAROCAP® Technology
First introduced in 1985, the Vaisala BAROCAP® silicon-based micromechanical pressure sensor offers reliable performance in a wide range of applications from meteorology to industrial use. BAROCAP sensors combine two powerful technologies: monocrystalline silicon and capacitance measurement. They enable low hysteresis, excellent measurement accuracy and long-term stability.
Typical areas of application for air pressure measurement
- Meteorology:
- Weather stations
- Data acquisition buoys
- GPS meteorology
- Logging of environmental data
- Hydrology and soil science:
- Barometric pressure measurements
- Industry:
- Pressure-sensitive industrial products (e.g. laser interferometers, lithography systems)
- Aeronautics
- Exhaust gas analysis
Areas of application for pressurized systems
- Compressed air systems:
- Combination of dew point measurement and process pressure in real time
- Online conversion of the pressure dew point into the atmospheric dew point or in ppm
- Avoidance of ambiguities in dew point measurement values
- High-voltage systems with SF6 insulation:
- Check the condition of the SF6 insulation
- Early warning of moisture problems
- Immediate detection of leaks
- Measurement of dew point, pressure and temperature to calculate important parameters (SF6 gas density, normalized pressure, dew point at atmospheric pressure, ppm value)
- Combination of DRYCAP and BAROCAP technologies:
- Unique combination of pressure and dew point measurement for pressurized systems
