ELECTRONIC CONTROLLERS

The Fluid Systems Division supplies a diverse range of electronic controllers for the aerospace market and for non-aerospace applications.

 

Our aerospace controller products are used on the latest commercial and military transport aircraft, and regional and business jets. Our controllers include flight controls, utility controllers, and pump controllers.

 

Building on our aerospace electronic controller success, the Fluid Systems Division has launched an industrial and automotive market product line for controllers. Coupling aerospace and industrial controller experience positions the division to be the low-cost supplier of high-performance electronic control products for all applications.

 

Our controllers feature modern architecture that provides:

  • Redundant-channel, fail-safe design
  • Control and monitoring within each channel
  • System monitoring
  • System performance tuning
  • Control logic using complex programmable logic devices (PLDs)
  • Digital communication buses

 

Market Applications

  • Flight control actuation systems
  • Landing gear systems
  • Fuel pumps and valves
  • Munitions and missiles
  • Utility control systems
  • Fuel tank inerting
  • Fire suppression
  • Aerial refueling
  • Manual fuel control
  • Industrial spray evaporative cooling applications
  • Off-highway vehicle fluid transfer pumps
