AEROSPACE PRODUCTS

Hydra-Electric Co. produces and services high performance electro-mechanical products for pressure, temperature and liquid flow sensing. Hydra-Electric pressure switches can be used in gage, differential, vacuum, altitude and airspeed applications and on hydraulic, anti-ice, pneumatic, lube oil, fuel, potable water or cryogenic systems.

Other products include thermally operated (temperature) switches, liquid flow switches and aneroid operated valves for aircraft turbine engine gearbox and sump pressurization. Hydra-Electric’s extensive product range has been developed to meet the varied and demanding requirements of the aerospace industry. Products are designed to interface with all airframe, engine and ground support systems.

New products include various multi-function switches that provide dual pressure capabilities or pressure and temperature functions. By combining multiple switch functions into one assembly, these products offer space, weight and cost savings on new or retrofit aircraft programs.

PRODUCT CAPABILITIES

Pressure Switches are available with operating ranges from .25"H20 to 4,800 PSI.
Temperature Switch operating ranges from 10°F (-12°C) to 500°F (260°C).
Flow Switch operating ranges from 0.25 gpm to 30 gpm.
Altitude Switch operating ranges from sea level to 100,000 feet.

Switch service life ranges are available up to 1 million operating cycles. Switches are designed to operate in ambient temperatures from –85 °F to 400 °F, withstand vibration up to 25 G’s at 3,000 Hz and shock up to 250 G’s. Special switches can be designed to withstand vibration to 100 G’s and shock to 1000 G’s.

Hydra-Electric Aerospace Switches are designed to meet various specifications such as RTCA/DO-160, MIL-S-9395, MIL-S-28827, MIL-S-28788, MIL-STD-810 or MIL-STD-202. These requirements, among others, include: Environmental Test requirements such as Temperature Cycling, Humidity, Moisture Resistance, Salt Spray, Sand and Dust; Dynamic Tests such as Endurance, Vibration, Shock, Acceleration; and various Electrical Characteristic Tests such as Dielectric, Insulation Resistance, Contact Resistance and Bonding.
