Soon after Hydra-Electric was founded in 1948, the company introduced breakthrough technology to the aerospace industry, designing and patenting the snap action sensing of pressure by means of the negative rate disc spring, which employed an additional trim spring for pressure adjustment. This environmentally powered snap action design has since become the standard for critical aerospace applications.
Over the course of our history, Hydra-Electric has continued to introduce innovative designs for temperature and pressure sensing for a variety of aircraft programs. Within the past decade, we have introduced breakthrough technology in sensors, patent-pending technology that excels and addresses problems that can’t be addressed by older technologies.
Designing, developing and manufacturing pressure switches (and other products) is what Hydra-Electric does. Our pressure switch selection includes vacuum, gage, absolute and differential pressure switches. See us about items for monitoring and controlling pressurized operating systems.
