The TVPM system offers remote visual inspection of pipes with an interior diameter as small as 3.2 in. (80mm). This unit mounts its camera on a semi-rigid motorized cable using a double-sheave assembly. It has a maximum range of 150m (462 ft), and can be either pushed or pulled through a pipe. The drive motor and take-up reel are located outside the pipe and are not subject to chemical or mechanical damage from the pipe's interior environment. This also allows the camera unit to be smaller. This system features either a black-and-white or color TV camera, in 25- and 400-mm diameters, respectively. Both cameras have swiveling heads for close-up examination of the pipe interior walls. It supports Type 1 and Type 2 explosion-proof cameras for the internal inspection of natural gas supply pipes, or of ducts used in the petrochemical or mining industries.
