conductive pipe. The measurement is made with a coil. arrangement that produces a magnetic field that opposes the. primary field casing attenuation and phase-shift. The magnitude of the phase shift is a function of the casing electrical. conductivity, magnetic permeability and thickness of the metal present in the. field.
The long-tailed weasel is one of the larger members of the genus Mustela in North America, with a total length of 300â350 mm (12â14 in) and a tail comprising 40â70% of the head and body length. In most populations, females are 10â15% smaller than males, thus making them about the same size as large male stoats.
Weasel gets straight to the work stations via an optical guiding line. Speeds of up to 1 m/s on routes with an incline of up to 20 percent can be achieved. The Weasel is requested or sent to its destination manually by operating buttons or fully automated. The determined route controls the Weasel via predetermined waypoints.
