Application notes

Hermetic limit switches

for Pilatus PC-21, PC-9 and PC-7 doors. As well as detecting the position of the doors, the limit switches can be used to activate alerts in the cockpit to warn the crew of possible safety risks, such as depressurisation.

Limit switches offer

CIRCUIT BREAKERS

equip Embraer aircraft to protect electrical circuits against overloads or short circuits.

Circuit breakers offer

PROXIMITY SWITCHES

are essential elements of Gulfstream aircraft. They are critical components for the safety of landing gear control systems by providing reliable information on the landing gear status.

Cargo Loading products:

For cargo loading systems, Crouzet offers position and structural monitoring sensors, and electric motors. The proximity sensors are used to monitor the deployed/stowed position, opened/closed position of doors and latching mechanism. While, our structural monitoring sensors measure any deviation and deformation. And our high efficiency electric actuators are used to into doors locking systems.

Nacelle products:

For nacelle application, Crouzet has a large range of components, from sensors to motors. Our Proximity Sensors are integrated in order to monitor the deployed or stowed position of the thrust reverser door. In addition, our high power density motors actuate the electromechanical actuators of the thrust reverser while our force sensors measure any jamming or deviation of these ones.

Fuel pump products:

For safe operation, protection of electrical wiring is essential. Fuel tanks are protected from any ignition sources that could occur due to puncture caused by arcing. Crouzet proposes ground fault circuit breaker with arc fault which provides built-in test features that allow aircraft maintenance personal to verify that ground fault protection is functional or that a ground fault has occurred. In addition, our standard or custom actuating solution are integrated in fuel pumps.

Landing gear products:

Landing Gear proximity sensors provide signals to monitor landing gear position (up or down) and gear doors (opened or closed). Weight on Wheels (WoW) switches indicate whether the weight of an aircraft is resting in its wheels. This information reveals whether the aircraft is airbone or on the ground. High power density electric motors actuate the brakes and the direction of the landing gear systems. In addition, our structural monitoring sensors are integrated in electric actuators to measure any deviation.

Flight Controls products:

Flight control system interprets the pilot’s commands and moves the flight control surfaces (flap and slat) as necessary to achieve the desired response. The proximity sensors provide information about slats, spoiler, ailerons flaps position for a stable flight. While our electromechanical actuators associated with our force sensors are capable of moving the surface and holding the required position.
