AIRCRAFT (ENGINES AND SUBSYSTEMS)

United States | Oil Temperature RTD Sensors

RTDs are among the most accurate temperature sensors available, featuring high immunity to electrical noise. They use multiple RTD elements to monitor oil levels and temperature. The sensors include single/multi-element configurations, cold junction compensation, and are highly reliable, customizable, and reduce FADEC complexity.

United States | RTD Temperature Sensors

The fuel temperature RTD is hermetically sealed and utilizes various RTD elements like platinum wire wound. It provides high accuracy, stability, and repeatability, engineered for precise temperature monitoring in aircraft subsystems including nacelle, engine fuel, cabin control, and more.

United States | Aircraft Speed Sensors

Aircraft Speed Sensors, including Magnetic Reluctance and Hall Effect sensors, are designed to respond to magnetic field presence and interruptions. They are durable, reliable, compatible with electronic circuits, and capable of zero-speed detection.

United States | OSSD, Overspeed Shut Off Detector

The Overspeed Shutoff Detector features a Flanged Housing and Plunger Assembly that activates when engine instability occurs, contacting the Plunger Assembly and fracturing a Frangible Link. This action shuts off the signal controlling fuel flow, preventing catastrophic engine failure. Designed for single-use, it incorporates proprietary Frangible Link technology and a hermetically sealed sensing head for high reliability.

United States | Outside Air Temperature Sensors (OATS)

HarcoSemco produces various models of OAT sensors, crafted to rigorous standards with 3D modeling, in-house aerodynamic testing, and fine wire element winding. They are a cost-effective alternative to TAT sensors, featuring rugged, hermetically sealed construction, wide temperature range, and non-de-iced fuselage mounting.

United States | Magnetic Speed Sensor

HarcoSemco magnetic speed sensors convert motion to an electrical signal without requiring external power. The sensors are made of one-piece stainless steel, providing high accuracy and no moving parts. Ideal for applications like engine RPM and wheel speed, they are designed for harsh environments and meet aerospace quality standards.

United States | Bleed Air Temperature Sensor

HarcoSemco’s Bleed Air Temperature Sensors are crafted with RTD Elements enclosed in a metallic housing and terminated with flexible leads or connectors. The connectors can be hermetically or environmentally sealed. These sensors support various environmental applications, including wing anti-icing and cabin temperature control.

United States | Air Flow Sensors

HarcoSemco’s Air Flow Sensors include high-stability platinum RTDs, precision heaters, and electronic interfaces. They provide analog DC voltage outputs and are adaptable to various installations, operating on the "thermal dispersion" principle for low flow detection in avionics cooling systems.

United States | CFM56-7B Engine Harness

The CFM56-7B Engine Harness by HarcoSemco is tailored to address in-service failure mechanisms and prevent false EGT readings, leveraging an FAA-approved Supplemental Type Certificate. This harness boasts improved component materials and construction for enhanced reliability and long service life.

United States | Engine Harness and FADEC

HarcoSemco’s Engine Harness and FADEC are crafted to endure intense vibration and exposure to hazardous fluids in engine environments. Built with high-temperature materials, these harnesses ensure maximum reliability in critical on-engine applications.

United States | Fuel Cable

HarcoSemco’s Fuel Cables are designed for installation within aircraft fuel tanks and provide sealing against fuel intrusion, qualified for pressures up to 50 PSIG. These flexible conduits enhance durability and prevent fluid ingress.

United States | APU Cable Harness

The APU Cable Harness by HarcoSemco features an open-bundle construction for ease of maintenance. This design reduces external coverings, ensuring straightforward inspection and repair in less critical environmental zones.

United States | Blade De-Ice Harness

Designed for helicopter blade de-icing systems, HarcoSemco’s Blade De-Ice Harnesses withstand extreme rotational stresses, high-frequency movement, and temperature variations. These harnesses are validated through in-house endurance testing.

United States | Anti-Stall System

The anti-stall system by Extant Aerospace includes servo actuators and capstans to prevent aircraft stall conditions, aiding in nose-down maneuvers.
