Breakthrough Sensing Technology Sensors I Switches

Hydra-Electric’s sensors and switches have been put to the test across a wide range of critical aircraft systems. Flight Control Systems (actuators, rudder, elevator, aileron, spoilers, hydraulic reservoir) (fuel, lube oil, pneumatic controls) Environmental Control Systems Crew Oxygen Systems Waste Water and Portable Water Systems Anti-icing/ De-icing Systems Fuel Systems Landing Gear Systems Engine Systems (parking brake, hydraulic pump) Force Fight Hydraulic (Thrust reverser, engine fuel, lube oil, fuel filter, altitude, radar cooling) FOR A VARIETY OF MEDIA Oil | Fuel | Hydraulic | Air |...

Hydra-Electric’s patent-pending sensors excel where older technologies fail. PRESSURE Gage Absolute Differential Extend service life Deliver high accuracy Eliminate pressure spike damage Stay protected from electrical transients Remain safe at millions of pressure cycles Resist electro-magnetic HIRF interference TEMPERATURE MULTI-FUNCTION Achieve Linear Accuracy Achieve linear accuracy over a wider temperature range…and better manage your error budget. Error band with other sensors Error Temperature No need to compromise on the zero and span error at extended temperatures. For either...

PRESSURE Gage Absolute Differential TEMPERATURE LIQUID FLOW MULTI-FUNCTION • Premium Quality products from the industry pioneer and inventor of the first negative disc spring • Highest Level of Accuracy for achieving the deadband • Capabilities from custom design, enhanced design as well as many standard designs • Superior Manufacturability from having perfected building the rough set

Outperforming the competition in accuracy, reliability and robustness Hydra-Electric’s superior sensing technology... • AVOIDS burst diaphragms • EVADES broken wire bonds • SURVIVES pump ripple fatigue • ENDURES high speed impulses • ELIMINATES pressure spike damage • WITHSTANDS high cycle counts - one million or more cycles Surviving Pump Ripple Issue A Tier 1 manufacturer of hydraulic systems was encountering problems with high levels of pressure ripple due to impeller pump. Their existing configuration utilized sensors based on older technology which resulted in premature catastrophic...

Aerospace Innovation Since 1948 Over six decades ago, Hydra-Electric developed and patented the snap action sensing of pressure by means of the negative rate disk spring, employing an additional trim spring for pressure adjustment. This environmentally superior powered snap action design has since become the standard for critical aerospace applications. Hydra-Electric's designs were selected for numerous early military and space applications, including P80, F86, F100 through F104. X15, SR71, and U2 Aircraft; Mercury, Gemini, Saturn and Apollo Space Programs. Hydra-Electric's products have...
