Abstract

The device has a fault detector (30) evaluating condition of measuring equipments, and an estimator (70) that provides an estimate of a measured variable. A calculating module (105) provides a periodically reliabilized estimate (R2) of the variable by considering account measurements provided by valid measuring equipment. A parametric adaptation module (74) readjusts the estimate of the measured variable during detection of a defect of one of measuring equipments, where the calculating module determines a value of the variable by considering the reliabilized estimate. An independent claim is also included for a method for reliabilization of a value of a variable measured by measuring equipment.
