MV-LC0073 Compression Load Cell: Flange and Bottom Mounting

METRAVON MV-LC0073 is a compression load cell family whose mounting arrangement changes substantially with capacity. The reference spans 1-150 t: lower groups use a square flange layout, while higher groups are identified for bottom mounting. It should not be treated as one miniature envelope available at every rating. Choose the actual capacity and mounting group before quoting the base, mating contact or removal access.

Compare the lower-capacity compression load cell flange patterns

For 1-2 t, the metric table gives L1 81 mm, L2 65 mm, H48 mm, body-diameter reference 80 mm and a 6.5 mm fixing-hole reference. The 5-30 t group changes those values to 165, 135, 95, 120 and 12.5 mm respectively. Thus a larger rating can change both the base footprint and the support height. Use the exact rated drawing rather than enlarging holes in the original flange or assuming a spacer can make the two groups mechanically equivalent.

Treat the bottom-mounted groups as different base designs

The 50-80 t row gives H120 mm and a 220 mm body-diameter reference, with four M12 positions on a 196 mm circle. At 100-150 t, H becomes 180 mm, diameter 300 mm and the bottom references become four M16 positions on a 270 mm circle. The table identifies these as bottom mounting rather than supplying the earlier square L1/L2 layout. Obtain the underside detail, thread definition and usable engagement before making the base, including how the sensor can be installed or removed.

Use the 775-ohm input figure rather than a neighbouring bridge value

Rated output is 2.0 +/-0.015 mV/V with 10-12 V DC excitation. Input resistance is listed as 775 +/-5 ohms and output as 700 +/-2 ohms. Do not replace the input value with a familiar 750-ohm entry from another sensor or assume identical trim settings. For a replacement in a multi-support system, provide the other cells and reader arrangement so the actual excitation load and calibration can be reviewed. Delivered wiring identification is required where the available colour references disagree.

Size the support reaction and useful measured interval together

Include permanent attachments and preload when they act through the sensor, and determine the greatest individual support reaction for the real loading conditions. A nominal total divided by the number of supports is not sufficient where load distribution varies. The precision entry is 0.05% FS; it does not determine the finished scale result at small inventory changes or under an unspecified contact arrangement. State reference loads and allowable installed results at the points that matter to the project.

Confirm protection and acceptance for the selected physical version

The specification lists IP66, not an automatic immersion rating, with -40 to +85 deg C operation. Check the cable termination, external enclosure and maintenance exposure separately. The reference photograph illustrates a small body and does not identify every high-capacity mounting version. Ask the offer to include the selected rated drawing, contact requirements and supplied hardware. Verify repeated compression and unloaded return with that final arrangement; do not interpret the 200% FS safe-load entry as a general commissioning test load.
