METRAVON MV-LC0156 is a shear beam load cell with a recessed loading contact, listed for platform scales, pallet scales and weighing-module assemblies. Rated choices are 500 kg and 1, 2, 3, 5, 7, 8, 10, 15 and 20 t. The version drawing must resolve the contact, fixing positions and cable arrangement before an existing scale is modified.
Choose the shear beam load cell by its contact and fixing geometry
The reference table gives a 203 mm length and 36.6 mm width for 500 kg-3 t, increasing to 279 and 60 mm at 10 t and 318 and 70 mm at 15-20 t. The loading recess and fixing-hole dimensions change too. Compare the load-bearing insert, fixing surfaces and installed level, not just the outer length. A contact piece pictured beside the sensor does not establish that it is included or suitable for every rating.
Resolve the 7 t and 8 t drawing rather than ordering a dimensional group
The capacity list contains 7 t and 8 t, whereas one dimensional row is labelled 5-7.5 t and gives a 235 mm length. The 8 t version is not assigned to a dimensional row. Request the exact ordered drawing for these ratings; do not relabel 7 t as 7.5 t or automatically place 8 t in that row. The accepted order should identify capacity, contact dimensions and fastening pattern as one configuration.
| Item | Value | Selection notes |
|---|---|---|
| kg option | 500 kg | Review the lower-group drawing and loading insert. |
| t options | 1, 2, 3, 5, 7, 8, 10, 15, 20 t | Obtain exact 7 t and 8 t configuration drawings. |
| 500 kg-3 t length / width | 203 / 36.6 mm | Other contact and fastening dimensions remain necessary. |
| 10 t length / width | 279 / 60 mm | A longer body changes the required support space. |
| 15-20 t length / width | 318 / 70 mm | Plan access for the listed 14 m cable and contact service. |
| Excitation / temperature | 4-12 V DC / -30 to +70 deg C | Maximum excitation is 15 V DC. |
Match the cable group to the finished scale
The cable notes give 3 m for 500 kg-3 t, 6 m for the 5-7.5 t group, 10 m for 10 t and 14 m for 15-20 t, using a four-core 5 mm diameter lead. Confirm the cable supplied for the offered 7 t or 8 t version where the group descriptions do not settle the order. Output is 2.0 +/-0.002 mV/V, with 385 +/-10 ohms input and 351 +/-2 ohms output resistance. Check the indicator excitation and junction arrangement before retaining existing wiring.

Verify the loaded contact after rebuilding the platform
Establish the greatest reaction at each support with the platform tare and the intended loading positions included. Seat the loading components, finish the cable route and record zero before applying reference loads at the agreed positions. Compare repeated loading, unloading and corner response if the platform requires it. The 30-minute creep entry is +/-0.02% FS; assess a held load separately when materials remain on the scale. Do not treat an overload limit as permission for uncontrolled impacts.
Rating labels and contact scope
Q1. Can a 7.5 t unit be ordered from the dimensional-row label?
The published capacity list does not establish 7.5 t as an offered rating. Confirm any requirement for that exact capacity before ordering. Do not substitute a drawing-group label for the nameplate capacity and calibration record.
Q2. Are the recessed insert and mounting hardware included?
They need an explicit scope of supply. Identify the contact piece, fasteners and any weighing-module parts on the proposed assembly drawing and quotation. Inspect retained parts for seating and wear before approving a sensor-only replacement.
