Vacuum Negative Pressure. a gauge measuring negative pressure, that is, pressure lower than atmospheric or barometric pressure is called a vacuum pressure gauge. However, since vacuum pressures fall below zero on a gauge pressure scale (psig), we use the term negative pressure because values below zero are considered negative. see the attached illustration. any negative pressure significantly below standard atmospheric pressure (760 torr/mmhg, 29.9 inhg or 14.7. vacuum pressure (figure 2 labeled c) is a measure of the pressure of a gas in a space where the pressure is lower than atmospheric pressure. a vacuum gauge is an essential tool for measuring negative pressure and maintaining optimal performance in various. The term negative pressure is somewhat of a misnomer because, in reality, pressure cannot be negative—it is always zero or positive. some engineers may not refer to vacuum at all but instead speak of “low pressure” or even “negative pressure”. This occurs when the application requires monitoring both. This gauge is calibrated at atmospheric pressure and reads only negative pressure or vacuum. vacuum also is often referred to as negative pressure (or soft vacuum).
