Monitoring for a Chemical Fume Hood     with plastic which was
then saturated with water. The chemicals were washed into a sump
and the fumes dispersed into the atmosphere. Management began
searching for a general purpose wireless datalogging solution to
monitor the lab room's pressure differential, which had to be
negative to the space outside   • Pressure, Its Units of Measure
and Pressure References     pressure measurement is abbreviated
as "G". At sea level, 0 PSIG (Gage) is about 14.7 PSIA. In.
Denver, 0 PSIG is about 12.5 PSIA. It is possible to have a
negative gage pressure. A vacuum would be. about -14.7 PSIG at
sea level. Transducers with gage references are usually
constructed by opening   • MEMS Pressure Sensors - Pressure
Measurement Types     . The measurement technique can involve
capacitive or resistive (piezoresistive or pressure sensitive
resistors). Piezoresistive designs are shown in Figure 1. Vacuum
