MV-LC0001 High-Capacity Compression Column Load Cell, 10-1000 t

METRAVON MV-LC0001 is a compression column load cell for high-capacity weighing supports, with a nominal range of 10-1000 t. It is selected as part of the load-bearing assembly: the sensor, upper contact, lower seat and surrounding restraint must work together. A high capacity does not establish that an existing seat or support plate can be retained. Compare the rated outline and the complete installed height before choosing a replacement.

Choose the compression column load cell from the support reaction

For a platform, vessel or hopper, determine the largest reaction at each support from the actual structural arrangement and loading conditions. Dividing total contents by the number of sensors is not enough where reactions are unequal or external forces are present. Include the empty structure, operating load and relevant transient conditions in the assessment. The sensor rating does not provide the structural capacity of the foundation, supporting frame or restraint. Submit those interfaces with the required useful weighing interval.

Check column height and both contact diameters by rating

The metric table distinguishes body height A, lower-to-shoulder reference B and full vertical reference C, together with upper D, lower E and body F diameters. For example, the 30 t row gives C=120 mm and D/E/F=50/64/75 mm, while 100 t gives C=200 mm and D/E/F=109/96/126 mm. Do not reuse a seat based on the outer body diameter alone. Obtain the rated drawing for capacities not covered by a displayed dimensional row, including the 10 t end of the nominal range. Use a controlled metric drawing for machining, including the complete datum definitions.

Distinguish the bare column from the pictured mounting assembly

The reference photographs show both a column sensor and a surrounding plated assembly. They do not establish that the plates, rods, seats or restraints are included in every sensor order. Define the supplied items, their total stack height and how the load is centred into the contact surface. A self-centring description is not a quantified allowance for side load, travel or angular error. Any uplift restraint or lateral stop needs its own reviewed design and clearances; it must not bypass the measurement in normal operation.

Match the 1.5 mV/V bridge before retaining the indicator

The electrical reference is 1.5 +/-0.01 mV/V with 10-12 V DC excitation, 750 +/-20 ohms input resistance and 700 +/-5 ohms output resistance. Confirm the indicator excitation, input range and calibration method rather than assuming a 2.0 mV/V replacement. For a PLC process channel, specify a suitable bridge acquisition or conditioning stage. Obtain the delivered terminal functions: the reference colour list and circuit show inconsistent signal polarity, so colour copying alone is not a release method.

Verify the final support assembly under working conditions

Agree reference loading and record repeat response, unloaded return and any required position or corner checks for the completed structure. The listed precision is 0.05% FS and temperature effect is separately 0.05% FS per 10 deg C. Check the intended working increments and actual sensor temperatures against those full-scale entries. The operating range is -40 to +85 deg C. Confirm alloy steel or stainless steel and the delivered IP67/IP68 sealing version for the installation, not the stronger grade by default. The 200% FS safe-load entry does not approve a proof test of the complete scale or its support steelwork.
