Precision Instrumentation for Uncrewed Aircraft Systems
Custom thermocouples, RTDs, wire harnesses, and Aerosensor aerodynamic measurement probes — engineered for the weight, space, and accuracy demands of UAS development and flight test.
Lightweight, Compact Instrumentation for Uncrewed Platforms
UAS development places unusual demands on instrumentation: every gram and every millimeter affects flight performance, and sensors must hold calibration through vibration, temperature swings, and repeated flight cycles. K-Tec Systems manufactures custom thermocouples, RTDs, and wire harnesses in-house, and serves as the authorized U.S. distributor for Aerosensor precision aerodynamic probes — giving UAS engineering teams a single, qualified source for temperature, pressure, and flow measurement.
Aerosensor’s compact multi-hole probes, Kiel probes, and yaw pitots are manufactured down to a 1.6mm minimum diameter using Direct Metal Laser Sintering (DMLS), with titanium available for weight-critical builds. Paired with K-Tec’s custom wire harnesses and temperature sensors, the result is a flight-ready instrumentation package built to your platform’s exact constraints.
Where K-Tec Instrumentation Supports UAS Programs
From bench-level propulsion testing to in-flight aerodynamic data acquisition, K-Tec’s instrumentation is sized and engineered for uncrewed aircraft constraints.
Air Data Sensing for Flight Control
Compact Aerosensor probes for airspeed, angle of attack, and yaw measurement feeding flight control and air data systems. Minimum diameters as small as 1.6mm suit small and medium airframes without compromising aerodynamics.
Propulsion & Powertrain Testing
Custom thermocouples and RTDs for motor, battery, and engine temperature monitoring on electric, hybrid, and small turbine UAS propulsion systems. Inconel-sheathed probes available for high-temperature zones up to 980°C.
Flight Test Instrumentation
Lightweight, low-drag probe configurations for in-flight aerodynamic data acquisition. Yaw pitots for simultaneous dynamic pressure and yaw angle measurement, supporting flight test correlation with wind tunnel and CFD data.
Airframe & Nose-Mounted Sensing
Multi-hole probes with optional integrated static ring for accurate static pressure measurement on UAV noses, where low-pressure-gradient conditions require additional precision.
Wind Tunnel Development Testing
Kiel probes, multi-hole probes, and Kiel rakes for total pressure, static pressure, and three-dimensional flow vector measurement during UAS aerodynamic development. Individually calibrated probes with lookup tables ready for real-time or post-processing workflows.
Custom Wiring & Sensor Integration
Custom wire harness assemblies built to your routing and weight requirements, integrating sensor leads throughout the airframe — built for reliable signal integrity under vibration and repeated flight cycles.
Instrumentation Built for UAS Constraints
Custom temperature sensors and wiring manufactured in-house, paired with Aerosensor’s compact aerodynamic probe line — sized, weighted, and rated for uncrewed platforms.
