Mechanical hysteresis problems associated with pressure sensors based on interferometric measurements of diaphragm deflection are discussed. The source and importance of each contribution to the net hysteresis is calculated and compared with experimental results. Possible methods to decrease hysteresis effects are presented. Based on these suggested methods, new sensors have been manufactured and their hysteresis evaluated. The results demonstrate that significant reductions in hysteresis can be achieved with minimum cost. Future sensor development will focus on materials selection and manufacturing methods to fully realize these improvements.
