Absolute Pressure and Gauge Pressure on Caterpillar ET Software<\/a>

“Absolute” Pressure and “Gauge” Pressure<\/p>\n

\"\"<\/p>\n

Absolute Pressure is measured relative to a full vacuum (in the empty, air-free space), and uses absolute zero as its reference pressure. Pressure that is measured against Atmospheric Pressure (also known as Barometric Pressure) is called Gauge Pressure.
\nAverage Barometric Pressure (1 ATM) at sea level is ~14.7 Psi (100 Kpa) or 1 Bar.<\/p>\n

\"\"<\/p>\n

As Figure 1.1 and 1.2 above, we can find the formula for the Absolute Pressure:
\nAbsolute Pressure = Atmospheric Pressure + Gauge Pressure<\/p>\n

#Related Information:
\nAtmospheric (Barometric) Pressure Sensor
\nThe correct reading for the Atmospheric Pressure Sensor is between 50 kPa (7.3 psi) and 100 kPa (15 psi).<\/p>\n

Altitude Derate
\nThe Engine may be derated due to high elevation. Use Cat ET to check for an active Engine Derate on the Status Flags screen.<\/p>\n

There are no Event Codes that are associated with the Altitude Derate.<\/p>\n
