Chell Instruments, a world-leading gas measurement and control specialist, has unveiled its smallest digital pressure scanner to-date, the picoDAQ. Measuring just 83.4 x 14.8 x 9.6mm, the device is designed for high-accuracy pressure testing in applications where space is at a premium but precision is critical.
Jamie Shanahan, director of Chell Instruments, said: “Even the slightest variation in pressure can impact performance — meaning every part, place and condition must be measured with absolute accuracy. To give our customers even greater versatility, we are proud to introduce our smallest pressure scanner yet, built to fit into even the most confined testing environment.”
Despite its compact size, the picoDAQ delivers up to 0.03% FS accuracy output. As a fully configurable smart pressure scanner, it can output pressure data in engineering units over Ethernet and CAN, using both CAN-FD and ‘classic’ CAN. The unit incorporates 17 absolute transducers, thermally compensated and conditioned to provide 16 absolute or differential measurements relative to one reference port.
With a rugged outer casing and IP67-sealed components, the picoDAQ is particularly suited to automotive and aerospace testing. Mr Shanahan added: “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. Given these sectors’ need for accuracy and continual improvements in speed and performance, we are confident the picoDAQ will give our clients new ways of enhancing aerodynamics.”
Chell Instruments has been providing pressure, vacuum and gas-flow measurement equipment since 1976. Its technology supports sectors including aerospace, pharmaceuticals, energy and motorsport. Mr Shanahan concluded: “At Chell Instruments, we never stand still and this is reflected in how we consistently introduce new innovations to satisfy more test applications. With the picoDAQ joining our range, we are giving customers even more opportunity for multi-point pressure scanning in the tightest and most demanding applications.”
