Weighbridge load cells operate inside a support arrangement that carries the deck and accommodates its movement. Replacing the measuring element can change installed height, contact geometry and load sharing. Identify that assembly before selecting a sensor with the same tonnage.
The load head and restraint belong in the survey
Record the existing cell, upper and lower contacts, installed height, fixing points and cable route. Inspect the deck clearances and restraints under the approved maintenance procedure. Mechanical support and safe unloading of the structure must be planned by qualified personnel before components are removed.
| Interface | Evidence needed | Fit risk |
|---|---|---|
| Vertical load | Contact geometry and complete assembly height. | A changed support can redistribute the deck load even when its rating matches. |
| Movement | Permitted deck travel and restraint arrangement. | The sensor must not become an unintended lateral stop. |
| Electrical | Sensitivity, bridge resistance, terminals and existing instrument. | A mechanically compatible sensor can still alter the summed response. |
| Acceptance | Scale requirements, tests and any applicable approval conditions. | A component specification is not proof of approval for the completed scale. |
Weighbridge load cells cannot be selected from capacity alone
METRAVON MV-LC0175 is a documented compression load cell with 10, 20, 25, 30 and 40 t options. Its published applications include vessels and test machines. Those data do not establish it as a direct replacement for a particular weighbridge or as an approved component of a regulated weighing installation.
Use its drawing and electrical data only as inputs to a compatibility review. The listed height with the illustrated head differs from the body height, and the head connection changes with rating. If a proposed installation cannot demonstrate suitable load introduction and movement, do not proceed on the basis of capacity or external appearance.
Keep fault diagnosis separate from the purchase decision
A position-dependent error may come from binding, debris or a support problem. Preserve the original readings and inspect those causes before condemning a cell. The bridge and installed-test guide explains why a resistance result and a scale performance result are different evidence.
After an approved replacement, repeat the required position, span and recovery checks and document the actual assembly. For regulated use, confirm the applicable requirements with the responsible service or authority; do not infer permission from a catalogue accuracy figure.
Q1. Can only the failed cell be changed?
Possibly, if the replacement is compatible with the remaining supports and electrical network. Establish that before ordering, then verify the assembled scale. Equal capacity alone does not justify mixing different cells.
Q2. Does recalibration compensate for a different support height?
No. Calibration adjusts the measurement relationship; it does not restore the intended deck geometry or restraint clearance. Correct the mechanical arrangement first.
Summary
Send the existing support drawing, sensor identification and scale requirements for a compression-sensor compatibility assessment. Treat a proposed model as unapproved until the complete application has been checked.
