Miniature cold-wire thermometer

With a cost and size at at least an order of magnitude smaller than a conventional CCA bridge systems, this miniature unit provides all the necessary functionality to carry out temperature measurements with minimal complexity. The system includes a built-in fourth-order butterworth filter and amplifier. Probes can be socketed directly into the board, or attached using extension leads; a compensation network is included for extension cables (if used).

Miniature hot-wire anemometry system

This system provides an ideal alternative to high-cost, rack-mounted hot-wire systems for turbulence measurement. The ultra-miniature footprint is ideal for model-embedded instrumentation, while the low cost of the units make large channel-count rakes and arrays for simultaneous spatial correlations a real possibility.

The low cost and simple operation of the unit are ideally suited to educational applications, while the small size means this cold-wire system can be easily added to small-section table-top wind tunnels and demonstrations.

The high fidelity, minimal signal noise and 5 kHz bandwidth provide high-quality velocity statistics down to the dissipation range in many common measurement applications, while the probe compatibility allows continued use of existing hot-wire probe supplies.
