Yes, Krystal Bond Technology can be used in this type of application. AST refers to this as a Compound Sensor. A compound sensor is a gauge or sealed gauge sensor that is calibrated to emulate an absolute range. For example: 0-100 PSIA sensor = -14.7 to 85 PSIg sensor or 0-7 BARa sensor = -1 to 6 Barg sensor This option offers the ability to measure in PSIg ranges below 0 PSIg, avoiding the errors of absolute sensors that are seen during changes in daily barometric pressure or changes in altitude.
