An apparatus and a method for monitoring the condition of one or more joints each formed between two adjacent flanges 10a, 12a are provided. The apparatus comprises: one or more gasket bodies 14a, 14b formed of a deformable material for positioning between adjacent flanges 10a, 12a; and a transmission line 16 for positioning between adjacent flanges 10a, 12a and in contact with at least one of the one or more gasket bodies 14a, 14b. The apparatus further comprises means for determining changes in the characteristic impedance along the transmission line 16, where a change of characteristic impedance is indicative of a deformation of the one or more gasket bodies 14a, 14b and the condition of the one or more joints. |
