Home/air pressure

Wittich & Visser offers you barotransmitters, barographs and barometers for measuring and recording air pressure.

  • Aneroid precision barometer model 103 for the measurement of absolute atmospheric pressure.
  • Electronic measuring sensor Series 3311 serves for electrical transmission of the absolute atmospheric pressure.
  • Barograph for recording atmospheric pressure.
  • The barograph registrates air pressure on a constant basis. The instrument is transportable and robust and can be used in extreme circumstances.
  • Known worldwide for its consistent reliability and outstanding performance (±0.05% FS accuracy), the Model 270 has been used in applications such as Weather Monitoring, Avionics Systems, and Crucial Compensation of Barometric Pressure in Laser Interferometers.
  • Low cost and high performance (±0.25% FS) make this pressure transducer an exceptional value. This compact, environmentally rugged pressure transducer is available with optional 0.1% FS accuracy, and 5 VDC excitation with 0.5 to 4.5 VDC output (for solar powered applications).
  • Designed for the environmental extremes found in Automated Weather Systems (AWS), the 278 offers exceptional long-term stability - better than 0.1 mb/yr. This unit is available in 500 to 1100 hPa/mb, 600 to 1100 hPa/mb, and 800 to 1100 hPa/mb pressure ranges with choice of 2.5 VDC or 5 VDC output.
  • Digital Pressure Gage: This highly accurate (0.02% FS) self-contained instrument has a 6-digit LCD display and a numeric keypad for access to engineering unit conversions. In addition, an RS-232 communications port is available for computer access.
  • Digital Pressure Gage without LCD display or numeric keypad. Used as the barometric standard in Automated Surface Observation Systems (worldwide) where accuracy, stability and versatility are essential.
