In standard English: "What does psig mean?"
The abbreviation stands for pounds per square inch gauge.
PSI is a standard unit of pressure, which may be converted to/from Pascals.
"Gauge" here means relative to surrounding atmospheric pressure.
So a reading of 100 psig means a pressure of 100 psi *above* the atmospheric pressure, which is around around 14.7 psi at sea level, making 114.7 psi absolute pressure.

What is -14.7 psig?
-14.7psig is the gauge pressure of an absolute vacuum.

-5 something is wrong
What must be done with an SCBA air cylinder that does not indicate a minimum 4000 PSIG prior to use?
The bottle should be exchanged for a fully charged cylindar.
What is the condensing pressure of 260 psig and the condesor outlet temperature is 100 degrees for r-22y how many degrees is the liquid subcooled in the condenser?
7 F
How do you calibrate PSIA transmitter. use 14.7 and the range is ATM to 600 PSIA. What would the 4-20mA set points be.?
The difference between Absolute Presure and Gauge Pressure is 14.7psi. So zero gauge pressure (0psig) = 14.7 psia. 600 psig = 614.7 psia. Calibrate the tranmitter so 4mA is obtained at 14.7 psig and 20mA is obtained at 614.7psig. The span will be 600 psi in both cases.
