Airbus A380 safer with Chauvin Arnouxs’ Help

Sensors used to monitor the performance of the new Airbus A380 are being installed with the help of the CA6541 Insulation Tester.

The wheatstone bridge sensors connected to the  planes’ fuselage to monitor stresses and strains during its Flight Tests, are installed with the help of the Chauvin Arnoux Insulation Tester. It is used to check that there is a high level of insulation from the adhesives to ensure there is little or no interference from contact with the  planes’ body. 

Because the CA 6541 Tester can give accurate resistance readings of up to 2  TΩeven on its lowest range of 50 V, Flight Test Engineers can install the monitoring devices and ensure the insulation is at least 20 GΩ; ideally 200-300 GΩcan be achieved and seen clearly on the instrument.

 

The sensors are used to monitor the pressures put on the plane at key points on the wings and fuselage where joints are made. These already have been calculated with computer simulation, but until the plane is in the air they cannot be sure exactly how they will perform. Data collected from the sensors is logged via onboard computers and the results analysed by the aircraft builders.

So with the help of small sensors and an advanced insulation tester, they can be safe in the knowledge the plane has been designed and built to the most exacting standards.
