 Measurement Principles of CTA by Dantec Dynamics

Primary manufacturer technical documentation. CTA principles: a heated wire in a Wheatstone bridge is held at approximately constant resistance by a servo amplifier. Probes: representative tungsten wire dimensions of 1 mm length and 5 micrometres diameter. Velocity sensitivity: known-flow calibration converts bridge output into velocity. Directional sensitivity and Temperature sensitivity: directional and ambient-temperature dependencies require characterization. Frequency response: system dynamics depend on wire and feedback response. No individual author or publication date is inferred.
