THE WORLD’S SMALLEST CONSTANT-CURRENT COLD-WIRE THERMOMETRY SYSTEM
Compact and fully self-contained constant-current ‘cold-wire’ bridge and driver system, with integrated output filter
This ultraminiature analogue constant-current cold-wire system is a fully self-contained, simple and economical solution for high-bandwidth temperature measurement needs. With a bandwidth of up to 5 kHz and no small-signal cable required, these units are ideally suited for electrically noisy environments. Compatible with leading brands of hot-wire probes and with a footprint of only 9 mm x 18 mm, this compact and simple analogue measurement solution is ideal for applications in model- and sting-embedded instrumentation.
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).

Applications
Miniature hot-wire anemometry system
Wind tunnel measurements
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.
Education
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.
Research
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.
