The Sondex Production Dual Caliper (PDC201) tool consists of two independent Calipers (X and y) set perpendicular to each other which measure the internal diameter of the well casing. The PDC is traditionally run centralized in a production logging toolstring. The caliper arms are spring-loaded to exert a constant radial force on the casing wall over the full measurement range. Both sets of arms can independently collapse down to tool diameter to pass through restrictions.
