Chell launches new instruments for in-flight engine testing


Chell Instruments has launched three products designed to meet the increasing requirements for in-flight testing of aircraft gas turbine engines.

Able to withstand extremely harsh environments and high altitudes, the new FlightDAQ-TL, Q-DAQ and FlightDAQ3, give class-leading performance for on-engine testing, with new features including DDS data protocol.

The FlightDAQ-TL is a highly configurable electrical scanner for PRT’s, thermocouples and external transducers.

Nick Broadley, Managing Director at Chell said, “The FlightDAQ-TL is a complimentary product to our existing line of FlightDAQ pressure measuring equipment. The FlightDaq-TL is highly configurable and can measure RTD’s, thermocouples, ratio-metric and amplified pressure transducers, using the in-built excitation supplies) or simply a voltage, current or resistance signal.

“It’s designed for on-engine as well as airframe applications and as such is tested to the D0160G vibration and shock standards.”

The second product is the Q-DAQ which is a miniature pressure scanner with a SQDC interface. It features 16 sensors which can be configured as absolute or differential (differential by nominating a channel as a reference). It also features an in-built heater to deal with the temperatures involved during flight testing. The Q-DAQ will out compensate pressure data (from -55°C to 90°C ) over Ethernet, IENA and CAN.

The final product is the FlightDAQ3. This is the latest development of the  FlightDAQ range and gives 32 or 64 channels of high accuracy pressure measurement in a heated enclosure. The FlightDaq 3 offers outputs of Ethernet, IENA and DDS.
