DLC-HD / IMPERIAL ENGINEERING SERIES
High Capacity Donut Load Cells
Heavy-duty compression donut load cell configurations for large dies, flange clamps and hydraulic testing. Start with the working force and credible impact peak, then resolve the installed support geometry.

Control contact stress, alignment and peak load
Safe overload is not an extended measurement range. Impact duration, eccentric load, support stiffness and repeated cycling must be evaluated separately from nominal capacity.
Material & configuration evidence
17-4PH stainless steel with a vacuum heat-treatment target of HRC 43–45. Confirm material and hardness documentation in the quotation.
DLC-HD configuration decisions
- 15,000, 25,000, 50,000 and 100,000 lbf capacity directions cover heavy clamping requests.
- An eight-gauge full-bridge layout is specified for the heavy-duty design; allowable eccentric loading remains configuration-specific.
- Laser-welded IP67 / IP68 options require a defined cable exit, immersion condition and approved configuration.

Verify compression calibration in the intended fixture
Request rated-load calibration points, zero return, bridge balance and environmental acceptance evidence. For IP68, define immersion depth and duration rather than relying on the code alone.
Agree rated force, approved drawing revision, excitation, sensitivity, cable / connector pinout and acceptance points before releasing a sample. Request configuration-specific dimensional and calibration records rather than inferring them from a series name.

- Stamping press force monitoring
- Heavy flange bolt clamping
- Cable-anchor and hydraulic jack fixtures
Application examples define a selection direction. They do not establish medical, aerospace or safety-system approval.
DLC-HD bore, output and ordering questions
Can I request a donut load cell 25000 lbs configuration?
Yes. Specify 25,000 lbf (111.206 kN) as the requested rated force, then add preload, dynamic peaks and fixture dimensions. Use DLC-HD as the series in your RFQ and confirm the rated force and installed envelope together.
Does 100,000 lbf mean 50 metric tonnes?
100,000 lbf is approximately 444.822 kN or 45.36 metric tonne-force. Use lbf and kN in the drawing and calibration scope to avoid ambiguity between force and mass.
