MV-LC0093 S-Type Load Cell with Fine-Pitch End Threads, 50-5000 kg

METRAVON MV-LC0093 is an S-type load cell with fine-pitch end threads for tensile and compressive force fixtures. It is documented over a 50-5000 kg family. Capacity changes do not always produce an obvious change in the front outline: different versions can share height and width but require another thread or side clearance. Identify the exact dimensional row before retaining the old couplings.

Check the S-type load cell thread even when the body looks unchanged

The 300 kg and 500 kg rows both show 77 mm height H, 50.8 mm width W and 24.4 mm thickness D. The end designation changes from M10 x 1 to M12 x 1. At 1000 kg the M12 x 1 thread and front outline remain, but thickness increases to 36 mm. Check the complete pitch and both mating fittings rather than assuming a matching nominal bolt size. Do not force a standard-pitch fitting into a fine-pitch measuring connection.

Allow the thicker versions to move clear of the fixture

For 50, 100 and 200 kg, the H and W references are again 77 and 50.8 mm, while D is 18.5 mm. The 2000 kg version changes to H86, W70 and D45 mm; 3000 kg uses H100, W80 and D50 mm. Include the side cable exit, coupling adjustment and any moving clevis in the clearance review. A bracket that accommodates the front silhouette may still touch a thicker body during loading or reversal.

Set up the millivolt bridge before judging a replacement by its zero

The electrical specification calls for 10-12 V DC excitation and 2.0 +/-0.015 mV/V rated output. Input resistance is 380 +/-5 ohms and output resistance 350 +/-2 ohms. Obtain the delivered wiring identification because the reference colour legend and circuit sketch disagree on signal-pair polarity. Verify the force sign and actual span with a suitable reference; an apparently stable unloaded display is not evidence that the old settings match the new unit.

Accept the assembled axial force path

Specify the tensile and compressive working points, any preload and how the end fittings articulate. Compare the required references during loading, unloading and reversal, then inspect empty return. The listed precision entry is 0.05% FS under the applicable sensor conditions. It does not remove coupling strain or establish the complete test-machine error. Confirm the IP67 or IP68 version and relevant termination conditions on the offer, rather than treating the two entries as a blanket immersion claim.

For another 500 kg layout with M12 x 1 ends, compare MV-LC0094: its height and front width differ, so the shared thread is not a replacement approval.

Request MV-LC0093 with the exact rating, thread pitch at both ends, side-clearance drawing, force-reversal sequence and reader excitation.
