MV-LC0077 Saddle-Seat Bridge Load Cell for Weighing Supports

METRAVON MV-LC0077 is a saddle-seat bridge load cell with a curved upper contact reference and separate base fixings. The technical panel gives 10-60 t, but the dimensional table labels its capacity column kg while listing groups that resemble the tonne-range family. Confirm the actual rated configuration and drawing units before ordering. The outline dimensions below distinguish the two bodies; they do not correct that capacity-unit inconsistency.

Identify the saddle-seat bridge load cell by the full outline

The smaller reference body lists L390 mm, L0 345 mm, H127 mm and B56 mm, with RC R80, diameter-18 base-hole references and M16 auxiliary thread labels. The larger body gives L500, L0 445, H173 and B86 mm, with RC R90, diameter-22 holes and M20 thread labels. Because the capacity-column units need confirmation, use these groups for identification until the offered rating is tied to a corrected drawing. Do not assign a tonne rating from a photograph or silently reinterpret the kg heading.

Item	Value	Selection notes
Technical capacity entry	10-60 t	The dimensional capacity heading needs confirmation.
Smaller L / L0 / H / B	390 / 345 / 127 / 56 mm	Identification references only until rated units are matched.
Larger L / L0 / H / B	500 / 445 / 173 / 86 mm	The longer and taller group needs its own installation review.
Smaller / larger RC	R80 / R90	Confirm the mating load member and approved contact arrangement.
Base-hole references	18 / 22 mm	Do not select fasteners or capacity from hole diameter alone.
Auxiliary thread labels	M16 / M20	Pitch, purpose and permitted use need the delivered drawing.

Review the curved seat and its mating load member together

The RC reference describes the illustrated curved contact; it is not a universal approval for any shaft, pipe or rounded loading piece of a similar radius. Submit the mating member, contact width and surrounding supports in section. Include the intended contact movement and any restraint or anti-lift arrangement required by the equipment. The auxiliary thread labels do not establish their purpose as load-transfer attachments, and no tightening torque or alternative force path is specified by this outline.

METRAVON MV-LC0077 saddle-seat bridge body and separate base fixing outline — 10-60 t technical family with two outline groups; confirm the capacity-to-drawing match before approving the saddle and base.

Check the bridge specification without assuming another support will fit

The electrical values are 2.0 +/-0.01 mV/V, 10-12 V DC excitation, 750 +/-20 ohms input resistance and 700 +/-5 ohms output resistance. These may match the nominal channel values of another weighing support while the mechanical contacts remain different. Identify the existing indicator, junction box and other cells when planning a replacement. Use delivered wiring confirmation and controlled loaded sign checks. Recalibration cannot make an unmatched saddle or base into an approved mechanical assembly.

Turn a preliminary enquiry into an installable support specification

Supply the required support reaction, load-member drawing, base steel and fixing pattern, old sensor label and permitted installed height. Request a response that ties the actual rated capacity and units to the complete saddle, base and electrical records. After the arrangement is approved, agree reference-load positions, repeatability and empty return for the actual scale. The 0.05% FS precision entry and 200% FS safe-load limit do not define the complete scale tolerance, loading test or protective function.

If the existing support includes a separate steel ball and loading head, the MV-LC0076 ball-loaded assembly is a more relevant geometry to review. Check the complete contact set and height instead of adapting either body to the other support without approval.

For MV-LC0077, send the old label, required reaction, mating saddle member, installed height and base drawing, and request corrected rated capacity units.

Saddle geometry and drawing-unit confirmation

Q1. Can the kg label be corrected to t on the purchase order?

Not without confirmation of the actual rated drawing. The technical range suggests a different unit convention, but an inference is not a supplier-approved specification. Request the corrected capacity-to-outline match and use those agreed units on the order.

Q2. Is the saddle-seat body interchangeable with a ball-loaded bridge?

The contact arrangements are different. Compare the complete loading member, installed height, base and restraint conditions rather than the bridge output alone. A shared 2 mV/V sensitivity cannot establish mechanical interchangeability.

Q3. What can the reference dimensions safely establish at enquiry stage?

They can help identify which body resembles the installed arrangement and which dimensions must be checked. They do not approve capacity, mating contact or fasteners while the units remain unresolved. Use the enquiry to obtain the matched rated assembly drawing before fabrication.
