System Details

AMETEK SFMS supplies sensing solutions for aircraft hydraulic systems, measuring reservoir quantity, line or component pressure, filter and pump differential pressure, discrete pressure conditions, and hydraulic-fluid temperature. The sensor suite supports the information needed to monitor fluid availability and operating condition across flight controls, landing gear, braking, utility actuation, and other hydraulically powered equipment.

 

Hydraulic quantity can be measured with capacitive transmitters, reed-switch devices, or float switches. SOI and thin-film pressure technologies support pressure and differential-pressure applications, while pressure switches provide discrete status and RTD sensors measure fluid temperature. Combined pressure and temperature packages may be considered where installation and system architecture favor consolidation.

 

  • Reservoir level and quantity sensing
  • Absolute, gauge, and differential pressure measurement
  • Filter and pump condition inputs
  • Discrete pressure switching and fluid-temperature monitoring

 

Hydraulic sensors must operate through pressure cycling, vibration, fluid exposure, temperature variation, electrical transients, and limited installation space. AMETEK SFMS tailors sensing range, materials, sealing, mounting, connector, output, and qualification to the aircraft application.
