20/40/60 Multi-finger Caliper Arms

Brief Introduction
The primary function is to detect the deformation, bending, fracture, perforation and inside corrosion of tubing or casing with multi caliper fingers.
Each caliper finger is connected to an independent non-contact displacement transducer that features small sizes, long service life, and high accuracy of measurement.
The tool can connect to LANDAU Cased-hole Logging System or Warrior Logging System, made by Scientific Data Systems (SDS) Inc., to constitute a casing imaging logging system. All logging data, including multi-channels of borehole diameter, cartridge temperature, and cable head voltage are acquired by the tool and sent to the surface system via telemetry circuit and mono-cable.
