Gas measurement and control solutions specialist Chell Instruments has launched its smallest digital pressure scanner to date, the picoDAQ. Measuring just 83.4 x 14.8 x 9.6 mm, the tiny dimensions of the picoDAQ make it suitable for high-accuracy pressure testing in applications where space is limited but precision remains critical.

“Even the slightest variation in pressure can impact performance – meaning every part, place and condition must be measured with absolute accuracy,” explains Jamie Shanahan, director of Chell Instruments. “To give our customers even greater versatility, we’re introducing our smallest pressure scanner yet, built to fit within even the most confined testing environment.”

Despite its ultra-compact size, the picoDAQ does not compromise on its measurement capabilities, delivering up to 0.03% FS accuracy output. As a fully configurable smart pressure scanner, the new device can output pressure data in engineering units over Ethernet and CAN, using both CAN-FD and ‘classic’ CAN.

The picoDAQ makes use of 17 absolute transducers which are thermally compensated and conditioned to provide 16 absolute or differential measurements relative to the one reference port. Due to its rugged outer casing and components sealed to IP67, the picoDAQ is especially valuable within automotive and aerospace testing.

“From wind tunnel to on-track or in-flight testing, our pressure scanners are vital tools in the design, development and validation of aerodynamics in vehicle and aircraft testing,” says Shanahan. “Given these sectors’ need for accuracy and continual improvements in speed and performance, we’re confident the picoDAQ will give our automotive and motorsport clients new ways of enhancing aerodynamics.”
