Druck DPI 142 Data sheet

Precision Barometric Indicator

• Ranges up to 50 psi absolute

• Precision 0.01% FS

• Long term stability 0.01% FS/yr

• Altitude display in feet and meters

• Programmable analog output

• RS232 and IEEE 488 communications

The DPI 142 is a high accuracy barometric indicator with digital communications suitable for integration into any datalogging or integrated information system. It provides highly accurate

readings using the resonant pressure sensor to better than 0.01% FS over 10°C to 40°C, with excellent long term stability. It can be used as a transfer calibration standard in laboratories or as a company reference standard.

The DPI 142 features easy to use software menus accessed via the front panel push buttons. The instrument also includes functional screens to measure barometric pressure, display a barograph (1 day, 2 day or 5 day trend), read altitude (feet/meters) and leak test pressure or altitude.

Digital communications allows easy data transfer of instrument readings and the analog output option enables the user to set a selectable output to be proportional to readings of pressure or altitude.
