MV-LC0125 Cantilever Beam Load Cell, 500 kg to 20 t

METRAVON MV-LC0125 is a cantilever beam load cell for platform, hopper and tank weighing assemblies. Its single-ended shear-beam arrangement has a bolted fixing end and a separate recessed load end. The documented family covers 500 kg to 20 t, with dimensions grouped by capacity. Choose the beam together with its mounting surface and load-introduction hardware, not from rated capacity alone.

A cantilever beam load cell can change holes without changing its envelope

The 500 kg-2 t group and the 3 t row both show a 203 mm length, 36.5 mm width and 43 mm height. Their fixed-end hole diameter D2 is different: 13 mm for the lower group and 15 mm at 3 t. Fixed-end centre spacing L5 remains 64 mm. An apparently identical replacement therefore needs a bolt and base review. Confirm the exact drawing row before releasing a mounting plate for manufacture or retaining the old fixing hardware.

Support the fixing end and leave the measuring section free

Provide the base drawing, fixing arrangement and the part that introduces force into the recessed load end. The beam must carry the intended load without the moving structure touching the base or an external stop during normal weighing. Side forces from a hopper connection, a rigid pipe or a misaligned loading piece can alter the measured reaction. A bare beam is not a complete tank support: identify restraints, overload stops and any uplift provision as assembly items on the offer.

Size from the largest support reaction, then check the installation space

For a multi-support vessel, start with the empty weight, maximum contents and centre-of-gravity positions. Equal division by the number of supports is only a starting calculation when loading is not evenly distributed. Filling impact, agitation and maintenance loads also need assessment. The 5 t reference is 235 mm long and uses 20 mm D2 holes; at 10 t these become 279 and 28 mm. A larger rating can require a different base, load fitting and surrounding clearance rather than a simple electronic adjustment.

Commission the beam through its installed loading piece

Connect the 2.0 +/-0.05 mV/V bridge to a compatible weighing indicator or conditioner with 5-12 V DC excitation. Input and output resistances are 380 +/-30 and 350 +/-5 ohms. The listed cable is 3 m long and 5 mm in diameter. After final assembly, check empty indication, reference loads, return after unloading and the relevant platform or vessel load positions. The +/-0.03-0.05% FS nonlinearity entry describes the sensor; mounting and loading effects remain part of the completed weighing result.

For an MV-LC0125 quotation, provide the required rating, base and loading-piece drawings, maximum support reaction, working cycle and indicator input.
