Surrey Sensors Ltd. is very pleased to announce the launch of its new ultraminiature MUHW-series constant-temperature hot-wire probes. With a footprint of only 28 mm x 9 mm, a bandwidth of 40 kHz and costing a small fraction of conventional hot-wire CTA bridges, this system is ideal for model-imbedded instrumentation applications and rakes.
“This has been a long time in the works,” says Dr. David Birch, Director of Research at Surrey Sensors Ltd. “Hot wire probes are highly specialized systems- easy to make, but difficult to get right.” This integrated hot-wire bridge includes an on-board square-wave test function, an analogue signal conditioner and can accommodate third-party hot-wire probes. “Our aim here was to keep it as simple as possible,” says Dr. Birch; “to bring back the very basic, simple system that used to either be available from smaller suppliers or built in-house.”
“We tried to keep the design as adaptable as possible,” adds Dr. Paul Nathan, lead hardware designer. “The bare PCB package gives the user the freedom to adapt the system as needed; it is compatible with most probes available on the market, and can either be directly socketed into a probe or connected with extension leads.”
“The market for turbulence measurement tools is small,” says Joe Braitch, Managing Director of Surrey Sensors Ltd. “This is the main reason why there are so few products on the market, and why these are so expensive. We’re launching this product as a way to give something back to the fluid dynamics research community that has supported us from our very beginnings.”
The MUHW-series constant-temperature hot-wire system is available from 1 February 2025, with pricing starting at GB£540.
