MV-LC0109 Diaphragm Compression Load Cell, 50 kg to 10 t

METRAVON MV-LC0109 is a diaphragm compression load cell with a raised central loading button. Its 50 kg-10 t family is intended for industrial force and weighing fixtures that need a relatively low measuring body. Two reference outlines divide the family at 5 t: the larger group changes the contact, mounting circle and body height, so the load rating and fixture drawing must be selected together.

Fit the diaphragm compression load cell below the intended contact

For 50 kg-5 t, the body diameter is 51 mm and total height is 25 mm, with a 10 mm loading contact designated SR50. The 6-10 t group increases the body to 88 mm diameter and 47 mm height, with an 18 mm contact designated SR150. Review the mating tool as a bearing pair, including its approach and any movement. The contact radius is not a statement that the sensor accepts an arbitrary tilt or a contact sliding across the top cover.

Check the underside pattern before reusing a fixture

The smaller group lists four M5 holes, 8 mm deep, on a 42 mm circle. The 6-10 t group uses four M6 holes, 12 mm deep, on a 72 mm circle. An existing fixture may therefore need both a new base and a different upper tool when capacity increases. Confirm thread engagement and the supported surface against the offered drawing. Leave the button and sensing region clear of any cover that could become a second force path.

Choose the rating for the working interval and foreseeable peak

The safe-overload entry is 120% FS. It does not provide a normal over-range measuring allowance or a machine stopping distance. Include fixture dead load, preload and the peak associated with an approach error in the assessment. Check the error entries against the force decisions the process actually makes; selecting the largest body is not a substitute for evaluating the lowest useful working force.

Verify the button assembly through the final bridge reader

Rated sensitivity is 2.0 +/-0.05 mV/V at 5-12 V DC excitation. The electrical load is 750 +/-30 ohms input and 700 +/-5 ohms output, not a presumed 350-ohm bridge. Complete the listed 3 m, 5 mm diameter cable routing, then compare reference forces through the intended loading tool during approach and release. Record zero return and repeat the decision points used by the machine. Agree dwell conditions separately if the +/-0.1% FS creep entry matters; it has no stated duration here.

For MV-LC0109, send the working force interval, peak event, upper contact and base drawings, available height and bridge-reader specification.
