  "textContent": "An impending bypass indicator (IBI) (22; 22'; 22\") includes a housing (30) having a fluid inlet (24) for admitting a fluid (11) into an interior (28) of the housing (30), and a piston (34) displaceable in the interior (28) of the housing (30) in response to a pressure variation of the fluid (11) in the interior (28), the piston (34) displaceable between a first position and a second position spaced apart from the first position. A piston magnet (50) is coupled to the piston (34). An indicator (22; 60) indicates an impending bypass of a component (20) in response to the piston (34) being in the second position. A housing magnet (54) engages the piston magnet (50) in the second position and generates a magnetic force acting on the piston magnet (50). A biasing element (56) biases the piston (34) towards the first position with a biasing force inferior to the magnetic force. An electromagnetic coil (58) adjacent the housing magnet (54) is selectively electrifiable to generate a second magnetic force opposite to the magnetic force.",
