  Barometric Pressure Measurement

Model 270: 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.

 
Model 276: 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).


Model 278: 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.


Model 370 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.

 

Model 470: Has the same functionality as the Model 370, but does not include the LCD display or numeric keypad. Used as the barometric standard in Automated Surface Observation Systems (worldwide) where accuracy, stability and versatility are essential.
