MV-LC0086 Heavy-Duty Load Cell for Scale Supports, 30-75 klb

METRAVON MV-LC0086 is a heavy-duty load cell documented for vehicle scales, hopper scales and rail-scale applications, with a nominal family of 30-75 klb. Its welded measuring body must be used with the correct load-introduction and support parts. A replacement decision needs the assembly drawing and bridge specification as well as the rated load; a similar-looking body does not establish that the existing scale hardware is suitable.

Review the heavy-duty load cell together with its contact hardware

The reference outline gives 260 mm overall length and a 216 mm longitudinal reference, with a 64 mm side-view width and 72 mm height. The central feature is marked diameter 20 x 19 and the end profile includes R25 references. These dimensions help identify the body, but do not define a complete load-bearing kit. Obtain the arrangement of saddles, contact pieces, restraints and supporting steel for the actual scale before deciding which existing parts can remain.

Check individual support reactions rather than dividing total capacity equally

Record the empty deck or vessel weight, maximum operating load and the loading positions that produce the largest reaction at each sensor. A wheel near one support or an unevenly filled vessel can give a different distribution from a centred test load. Check for a seized restraint, debris or contact with adjacent steel before attributing a changing reading to the cell. Increasing the nominal rating cannot remove a mechanical path that bypasses the measuring support.

Reconcile the bridge with the junction box and indicator

The listed excitation is 10-12 V DC, rated output is 2.0 +/-0.01 mV/V, input resistance is 750 +/-20 ohms and output resistance is 700 +/-5 ohms. Do not treat this as a 350-ohm replacement merely because both sensors have a nominal 2 mV/V output. Check the indicator excitation loading, junction-box adjustment method and the other connected cells. Use the delivered terminal identification and confirm the loaded sign; the available colour legend and circuit drawing disagree on signal polarity.

Test the completed scale where the load actually travels

After the mechanical installation is approved, establish zero and repeat reference loads at the relevant support positions. For a vehicle scale, include the required corner or section checks and loading direction in the agreed acceptance method. The sensor precision entry is 0.05% FS, while temperature effect is listed as 0.02% FS per 10 deg C. Neither figure determines the error of the assembled scale or proves legal-for-trade approval. Agree the required scale performance and applicable evidence separately.

Prepare a quotation that separates the cell from the mounting work

Send photographs of the existing load contacts, a dimensioned assembly view, the required klb rating and the indicator and junction-box details. Identify whether the offer must include replacement contact parts, cable termination or only the measuring body. The outline alone does not give a cable length or establish interchangeable mounting accessories. Confirm the selected enclosure version and how wash water or standing water reaches its termination; an IP67/IP68 family entry is not an unlimited-immersion statement.

For an MV-LC0086 quotation, include the rated klb value, load-contact drawings, support reactions, connected-cell details and required scale acceptance checks.
