BAROMETRIC REFERENCE BARO MODULE SPECIFICATIONS
Absolute pressure mode is achieved by using the BARO Reference Module to establish a datum. The PM and BARO sensor uncertainties were combined to
establish a new accuracy statement for readings taken in the absolute mode. It must be noted that the accuracy statement is valid for readings of 1 barA or
greater.
Accuracy
± 0.00725 psi, ± 0.5 mbar
Accuracy specications include all eects of linearity, hysteresis, repeatability, temperature, and stability within the specied operating temperature range
for one year.
Not
e: Exposure to environmental extremes of temperature, shock, and/or vibration may warrant a more frequent recertication period.

Pressure Connection
Cylindrical sensor tting of 5.8mm OD. A exible 4.8 mm [3/16"] ID tube is recommended to connection for both nVision chassis forms.
Mounting
BARO Module is secured using 3/8” 4-40 plastic screw.
!
WARNING: Plastic non-conductive screw must be used to comply with hazardous locations requirements.
!
CAUTION: Direct contact with barometric sensor may cause permanent damage. Direct sunlight on exposed BARO sensor may aect readings slightly.
