Chell Instruments has upgraded its FlightDAQ2 scanner to meet the evolving technical demands of aerospace test cells and flight applications.
The new design delivers pressure data with a quality of up to 0.02% of full scale, supporting critical testing across jet engine, airframe, and electrified flight development.
The FlightDAQ2, a scanner designed specifically for both test cell and flight use, now incorporates features adapted from the microDAQ3 model. Absolute transducers and an electrically driven valve for purge and re-zero functions have been integrated into the system, eliminating the need for high-pressure supply lines.
Engineers now benefit from a unit that is rigorously tested for both on-engine and airframe applications and conforms to DO-160G standards. Digital transducers provide precise measurements, and the device outputs differential or absolute data over Ethernet, Chell’s native protocol, IENA, and CAN at speeds of up to 400Hz per channel.
A quick disconnect plate further simplifies sensor reconfiguration during tests. The sensor utilizes a 24-bit analog-to-digital converter (ADC) per channel to supply engineering unit pressure data that is fully compensated for thermal effects, ensuring accuracy across varied test conditions.
“We’re pleased to have made further developments to our flightDAQ2. As a company supporting the aerospace sector with pressure scanning solutions, we are always looking for ways to enhance our technology with features that drive data-led design decisions for aircraft engineers,” said Jamie Shanahan, director of Chell Instruments.
The upgraded scanner is built to withstand harsh operating environments, maintaining performance even under significant thermal fluctuations. An in-built heater supports valve operation in low-temperature conditions, with functionality maintained at temperatures as low as –55°C.
UK-based Chell Instruments manufactures and supplies pressure, vacuum, and gas flow measurement equipment to sectors including aerospace, pharmaceuticals, energy, and motorsport.
“Designed for the demanding conditions of aircraft testing, the flightDAQ2 utilises 24-bit ADC per channel to deliver engineering unit pressure data that’s fully compensated for any thermal effects. It also features an in-built heater to maintain valve operation for altitudes where temperatures can dramatically decrease, operating as low as –55°C,” added Shanahan.
The enhanced FlightDAQ2 offers aerospace engineers a robust solution for reliable pressure measurement and control in demanding test scenarios. Additional technical specifications and further product information are available on the Chell Instruments website.
