Abstract
A method of positioning on a microwave waveguide a sensor (20) including an elongate metallic element (23, 24) comprising: selecting a tubular waveguide (12); determining the general orientation of the magnetic field (3) generated during microwave transmission; and positioning the elongate metallic element (20, 23, 24) substantially parallel to the orientation of the magnetic field (3). Connections (23, 24) of the sensor (20) extend longitudinally of the waveguide (12) and are connected to the outer wall (25) of the waveguide and the central conductor (16) of the coaxial cable (15) that powers the waveguide.
