Precision Instrumentation for Aerospace Testing
Custom thermocouples, RTDs, and Aerosensor aerodynamic measurement probes — engineered for engine testing, wind tunnel measurement, and flight test instrumentation.
Temperature. Pressure. Flow. From a Single Source.
Aerospace test programs require instrumentation that holds calibration under extreme temperatures, high vibration, and variable pressure conditions. K-Tec Systems manufactures custom thermocouples and RTDs in-house, and serves as the authorized U.S. distributor for Aerosensor precision aerodynamic probes — giving aerospace engineers and procurement teams a single, qualified source for both temperature and aerodynamic measurement.
Our sensors and probes are built to perform where standard catalog parts fall short. Whether you need thermocouple rakes for engine exhaust analysis, multi-hole probes for wind tunnel flow mapping, or RTDs for flight-critical temperature monitoring, K-Tec works directly with your engineering team from specification through delivery.
Where K-Tec Instrumentation Is Used
From ground-level engine test cells to in-flight data acquisition, K-Tec’s instrumentation is specified for critical measurement points across aerospace programs.
Gas Turbine & Engine Testing
Thermocouple rakes and RTDs for exhaust gas temperature (EGT) measurement, turbine inlet temperature monitoring, and multi-point thermal mapping on jet engine test stands. Inconel-sheathed probes rated to 980°C for high-temperature zones.
Wind Tunnel Aerodynamic Measurement
Kiel probes, multi-hole probes, and Kiel rakes for total pressure, static pressure, and three-dimensional flow vector measurement. Individually calibrated probes with lookup tables ready for real-time or post-processing workflows.
Flight Test Instrumentation
Compact, lightweight probe configurations for in-flight aerodynamic data acquisition. Yaw pitots for simultaneous dynamic pressure and yaw angle measurement. Titanium construction available for weight-critical applications.
Airframe Development
Multi-hole probes with optional integrated static ring for accurate static pressure measurement on aircraft and UAV noses, where low-pressure gradient conditions require additional precision.
Boundary Layer Profiling
Kiel rakes configured as one-piece monolithic DMLS structures or modular machined assemblies for simultaneous multi-point total pressure measurement across defined cross-sections.
Research & Development
Custom probe geometries and thermocouple assemblies developed to customer specifications. Aerosensor’s in-house calibration wind tunnel validates probes across wide yaw and pitch angles at airspeeds up to 275 mph.
