Description

The CPG2400 Barometer is low cost single channel Barometer
with a range of 8 to 17 psia. With an accuracy of 0.03%of reading
it is considered an excellent replacement for Mercury manom-

eters. Alternative ranges can be specied in a variety of units

including inches of Mercury (inHg A), millibar (mbar) and kilo
pascals (kPa). Built in peak and null functions provide a conve­nient way to analyze barometric trends.

Applications

The CPG2400 Barometer is used as a desk top or rack mounted
barometric reference for weather stations, laboratories, clean
rooms, nuclear power plants, pharmaceutical processing, health
care equipment manufacturing and Calibration of medical ra­diation equipment. The CPG2400 Barometer is used wherever
there is a need to have a precise measurement of barometric
pressure in manufacturing, testing, calibration or monitoring of
atmospheric pressure.

Functional Flexibility

The CPG2400 Barometer has a clear LCD display with an in­tuitive menu structure for easy navigation within the setup
screens. A membrane key pad provides the user the capability
to navigate within these menus to set display features such as
peak, null, pressure units. It also allows access to a password
protected calibration section for recalibration of the internal
sensor.

Communications

The CPG2400 Barometer can be operated from a remote
computer via a RS-232 or RS-485 serial port connection.

The serial port can be used to congure, read or calibrate the

sensor. This is useful when remote indication of the barometric
pressure is required. This is useful when remote indication of
the pressure is required. RS-232 is used for communication
over short distances and the RS-485 for longer distances and
multidrop applications.

Total Uncertainty is the combined uncertainties of all compo-

nents of a measurement at the approximate 95% condence

level (K=2). Total uncertainty includes the uncertainties of the fol­lowing: Calibration standard, repeatability, pressure hysteresis,

creep, linearity, and temperature eects over the compensated

temperature range.
