Force Magnitude Load Pin

Description

Proven technology developed by and exclusive to DLM; the Force Magnitude technology has been tried and tested in multiple applications and can be applied to various designs of shear pin load cell.

Making use of DLM’s intelligent Sirius amplifier mounted internally within a dual bridge load pin, the Force Magnitude technology enables the client to have a load pin which can read load in any direction across a 110 degree range. Typical load pins are required to be fitted so that the load is applied in one plane on the pin and will not produce accurate load readings if load is applied outside this plane. However, with Force Magnitude technology the load can be applied and accurately read in various locations around the pins central axis, eliminating the need for a load direction and preventing constraints to clients mounting arrangements.

Key features

  • Ability to measure magnitude of load in varying directions around the load pin
  • Wide application area of 110˚
  • Optional signal outputs of a single 4-20mA or RS485
  • DLM proprietary design

Applications

  • Subsea vehicles
  • Stinger load monitoring
  • Moorings
  • Applications where the load direction changes
