Tester for air temp. monitoring loop aboard aircraft - has switch with three positions connected to loop extremities and amplifiers, while microprocessor with memory unit processes data and displays results

摘要

The tester includes a switch (10) with three positions and an input (9) connected to an AC voltage generator (11). The switch terminals (12,13,14) are linked to the extremities (15,16) of a loop (18) for monitoring air temp. One of the tester outputs is connected to a variable gain amplifier (21) and an AC/DC voltage converter (22). The second output is connected to an amplifier (24) and a resistor (19). A microprocessor (27) with a memory unit processes data and displays the results on a display (28). USE/ADVANTAGE - For testing temp. monitoring loop on aircraft of Airbus or ATR type. Is simple with reduced dimensions. Light and portable.
