Due to its intrinsic flexibility, it is possible use the test bench with any other accessories of which characteristics are similar to the above components.

MAIN FEATURES:
The test bench is composed of 2 main subassemblies:
Main test chamber: where are present all the components under test interfaces and controls. In the rear part of the chamber are located the sensors and the relevant hydraulic connections and, 3 µm filters are provided on delivery and return line The sensors installed are several types like : pressure transducers having an accuracy of +/-0.05% F.S.; differential pressure transducers with an accuracy of +/-0.05% F.S.; PT100 temperature sensors with a precision of +/-0.5°C; fuel flow mass indicator (Coriolis effect ) class 0.5%V.L.; Ambient pressure transducer; mass transducer used to determine the fuel specific weight.
All these sensors are connected to the Analog-Digital acquisition data system that uses sensors with measurement converted in 4-20 Ma.
In order to grant a correct test fuel flow and pressure to the accessories the test bench is provided with a 3 high and low pumps driven by electric motors plus an vacuum pump and an hand pump.
An electric DC Power Supply 30V, 25A, 750W controlled by the application software installed on PC is present.
The test bench need to be fed with an air compressed flow at 15 bar 900Nl/min.
Control station: is realized with a PC, located on external console, where are loaded for each UUT the circuit configuration and the test parameters. In addition trough the software installed the authorized technician could get the access to the instrument/sensors for calibration. The software run in the Windows 7 OS and a further slave monitor is installed inside the test chamber to help the operator during the test, reporting or the same information shown on the PC monitor or, other pages like the synoptic circuit, involved in the accessory test. The software allows for each test to store the data acquired and give the possibility to print report in a customer format.

ACCESSORIES:
The test bench has been delivered with:
• Flexible hoses to hydraulic interface all the accessories to be tested
• P/N 131-1C-60 T53 and T55 Fuel Nozzle and fuel manifold test box
• P/N 131-1C-90 RR250 fuel nozzle test box
