AccuracyHydra-Electric has continued to innovate and improve upon the negative rate disk spring concept and its overall pressure sensing designs, applying its products to hundreds of aircraft and missile systems. Along the way, Hydra’s products have improved in aspects of accuracy and performance. A pressure switch must possess certain high characteristics of accuracy, repeatability and hysteresis.Our products tend to be very accurate, reacting and signaling within the pressure levels and tolerances for the product design Hydra-Electric’s switch pressure tolerance levels are very acceptable in aerospace circles and have been quite favorable for customers over the years. | ![]() |
