On-board sensors are developed by the designing department, from the first definition documents up to the operating agreement relating to the craft. This development phase consists in a document stage, a prototyping stage and a qualification testing stage; a large number of the tests are carried out in the installations of Thermo-Est (temperature, vibration, pressure etc.).
Thermo-Est has thus developed temperature sensors for brakes of aircraft such as the B777 and the RC/KC135 among others, airflow measurement sensors for the A380, ambient temperature sensors for the A380, and transmission unit and hydraulic control oil sensors for EC175 helicopters.
These examples must be supplemented by a number of other products, such as multiple-point temperature measurement harnesses, turbine temperature sensors and air-conditioning sensors.
Thermo-Est has reconciled the technical and regulatory requirements for on-board aeronautics sensors with development and production needs in accordance with the EN9100 quality system, by devoting a team of engineers and setting up a dedicated workshop for the requirements in the area.
Here are examples of the products we have made to customers' technical specifications, in accordance with the standards applicable to on-board sensors.
