DDE Miniature In-Line Load Cell

At a Glance

  • Capacities: 0-100N up to 0-50kN
  • Output: 2mV/V
  • Environmental Protection: IP65
  • Accuracy: <±0.30%/RC
  • Low Profile Design
  • Low Profile & Integral Mounting Threads Make it Ideal to use in Small Spaces
  • Designed for Both Tension and Compression Monitoring
  • Customisation Available to Suit Your Application
  • Excellent at Monitoring Fast Changes Thanks to its Low Deflection


Applied Measurements DDE miniature in-line load cell is suitable for use in both tension and compression and offers a very low profile body coupled with integral mounting threads to allow use in applications with restricted mounting space where other in-line load cell designs such as S-Beam load cells are too large.

The DDE’s small size means that weight is kept to a minimum, this, in conjunction with its low deflection, results in a high stiffness assembly and makes the load cell suited to the measurement of fast changes in load and high-frequency transients.

The DDE miniature in-line load cell is currently being used in many applications including automotive production, cable tension monitoring and suspension force monitoring.  Customised versions with different thread sizes, specific dimensions and interim capacity can also be provided if required.

For a submersible in-line load cell please see Applied Measurements DDEN fully submersible load cell which has a protection rating of IP68 suitable for long-term immersion.

Rod End Bearings for Tension Use

Designed to align forces through the principle axis of the load cell thus reducing the effects of extraneous forces, hence offering improved performance from the cell.

Rod End Bearings are used where tensile forces are being applied.

Maintenance-free rod ends are a complete units made up of a housing with both an integral shank (with an internal or external thread) and a maintenance-free spherical plain bearing, located within the housing.

Key Features:

  • Supports radial loads in a tensile or compressive direction.
  • Suitable for unilateral loads – can support alternating loads and alternating loads in combination with bearing GE..UK-2RS, please consult sales.
  • Zinc plated for corrosion resistance.
  • Are maintenance-free.
  • Fitted with radial spherical plain bearings GE..UK
  • Hard chromium/PTFE composite sliding contact surfaces.
  • Enables compact adjacent construction thanks to its thin-walled design of the eye housing.
