MV-LC0041 Compression Column Load Cell for Matched Seats

METRAVON MV-LC0041 is a compression column load cell reference for heavy weighing supports such as vehicle scales and vessels. Its upper and lower end contacts must be matched to the retained seats, not selected only from the cylindrical body diameter. The technical family is 10-50 t. The drawing gives a 150 mm overall reference and separately uses an SRE end-profile annotation with capacity-dependent values. Those entries are different features and should not be interchanged when checking the installation height.

Match the compression column load cell end contacts before reusing the seats

The reference outline shows a 76 mm body diameter, a 37.8 mm upper-end diameter and separate 19 mm end-height references. Its end-profile table lists SRE150 for 15, 20 and 30 t, and SRE210 for 50 t. Obtain the complete rated contact definition and mating seat geometry rather than treating SRE210 as a 210 mm sensor height. The 10 t technical rating has no corresponding row in that end-profile table, so it needs its own confirmed drawing.

Leave lateral clearance for the housing and the permitted support movement

The side view includes a 102 mm envelope reference across the body and lateral housing. This is not the cylindrical body diameter, and the exiting cable needs further space. Show both seats, the foundation and the supported structure in section, including guides, lift restraints and maintenance access. The reference mentions self-return behaviour but supplies no permissible rocking angle, restoring force or universal seat arrangement. Do not add a tight body collar that restrains normal movement without an approved installation design.

Check individual reactions instead of dividing total capacity equally

Provide the empty scale or vessel weight, maximum working load and governing loaded positions. An uneven vehicle position, foundation movement or pipe restraint can change a single support reaction. Choose a rated unit against those conditions and specify which seating parts are retained. A 200% FS safe-load entry is not a strength rating for a worn seat, foundation anchor or temporary lifting fixture. If a support needs replacement, the structure must be made safe under the project maintenance procedure before the old unit is released.

Use the actual 780-ohm input value in the retained weighing network

Excitation is listed as 10-12 V DC, with sensitivity 2.0 +/-0.015 mV/V. Input resistance is 780 +/-20 ohms and output resistance 700 +/-5 ohms. Do not substitute a familiar 750-ohm or 350-ohm bridge specification when checking the indicator and other connected cells. Obtain the delivered wire functions because the signal-colour list and circuit sketch disagree. Confirm the sign and reference weights after the new seats and cable route are accepted; a matching empty indication alone cannot verify the replacement.

Agree the installed result and exposure rather than extending application claims

The reference lists 0.05% FS precision and a temperature effect of 0.05% FS per 10 deg C, with operation from -40 to +85 deg C. Define acceptance at the useful scale loads and positions, including repeat loading and unloading return. The mention of rail weighing does not provide a dynamic-system accuracy or test-speed specification. For IP68, ask for the delivered sealing arrangement and agreed immersion conditions, and check the cable junction separately. Material grade and process-fluid compatibility also need confirmation for the actual supplied configuration.

Request MV-LC0041 with the required rating, upper and lower seat drawings, support reactions, available height and retained weighing-network details.
