Zeroing Absolute Sensors by Robert Clayton - Engineering Manager
This paper presents some of the problems of zeroing absolute sensors. It also discusses some of the solutions to these problems. The physical constraints which cause flows to move from viscous to molecular regions are presented along with how this information can be used to develop better techniques and hardware for accurately setting zero points on absolute pressure transducers and instruments.
Low Pressure Measurements by Robert Clayton - Engineering Manager
Low pressure (.2 to 5 psig) is one of the most rapidly growing segments of the pressure measuring market. It is, unfortunately, very difficult to make accurate calibrations of high accuracy gauge pressure instruments in this range. This paper discusses some problems and solutions found in making these types of calibrations. Techniques and types of necessary equipment for performing proper calibrations are discussed. The improved methods and the benefits in reduced uncertainty and time required for calibration are also discussed.
