A sensor arrangement (1) comprising a plurality of sensors (4, 5) and a measurement device (8), the plurality of sensors (4, 5) divided into sensor groups (2, 3), each sensor group (2, 3) comprising a number of sensors (4, 5), the groups (2, 3) being arranged such that the sensor groups (2, 3) are electrically matched, the sensors (4, 5) in a sensor group (2, 3) coupled in parallel with each other to form a sensor ladder (6, 7), the measurement device (8) arranged to compare electrical signals from each sensor group (2, 3) and to output an indication signal, characterised in that the measurement device (8) is coupled (9, 10) to each sensor ladder (6, 7) at an intermediate position and in that the coupling position of each sensor ladder (6, 7) are electrically equivalent to one another. Also a method of monitoring a plurality of sensors. |
