Patent ID: 8443654

Claim:
A device for monitoring an obstruction of at least two fluid filters of a fluid circulation system of a gas turbine engine of an aircraft, the device comprising: a first obstruction sensor to monitor a first fluid filter, and set up to send a first detection signal of an obstruction of the first filter, the first obstruction sensor including a Wheatstone bridge comprising at least one strain gauge resistor; a processor comprising a monitoring input linked to said first sensor to measure the first detection signal; and a second obstruction sensor to monitor a second fluid filter, and set up to send a second detection signal of an obstruction of the second filter, said monitoring input of the processor being connected to the second obstruction sensor to measure said second detection signal, the second obstruction sensor being connected in parallel with said strain gauge resistor; wherein the first detection signal is sent over a first predetermined variation range, the second detection signal is sent over a second predetermined variation range, distinct from said first variation range, and the processor is set up to identify the obstruction of one of the fluid filters as a function of one of the variation ranges of the first and second detection signals measured at the monitoring input.
