METRAVON MV-LC0132 is a plate-ring tension load cell for hook-scale and industrial tensile load-monitoring assemblies. The documented family covers 1-100 t. Two pin-connected ends carry the tensile force through the measuring plate, so pin centres, hole geometry and plate thickness must be reviewed with the adjoining clevises or other attachments.
Check plate-ring tension load cell thickness even when centres match
The 1-3 t and 5-8 t rows both give 196 mm overall length L, 80 mm plate height H, 130 mm pin-centre spacing L1 and 25 mm end holes. Thickness W changes from 30 to 40 mm. A clevis that clears one group may therefore not clear the other. At 10-15 t and 20 t, length and centres again match at 260 and 170 mm, but thickness changes from 45 to 50 mm. Match the entire row, not just the two hole centres.
Treat pin fit and articulation as part of the load assembly
The sensor-hole diameter does not specify the required pin tolerance, material or retaining arrangement. Obtain the mating assembly drawing and keep the tensile load in the intended plane. Define any movement and offset at the attachments instead of assuming the measuring plate tolerates unrestricted bending or twisting. For a hook-scale or lifting application, identify the required structural and approval evidence for the whole load-bearing assembly; the electronic measuring capacity is not that evidence by itself.
| Item | Value | Selection notes |
|---|---|---|
| 1-3 t L / L1 / W | 196 / 130 / 30 mm | End holes are 25 mm; check mating-pin fit separately. |
| 5-8 t L / L1 / W | 196 / 130 / 40 mm | The thicker plate can change required clevis clearance. |
| 10-15 t / 20 t W | 45 / 50 mm | Both rows have 260 mm length and 170 mm centres. |
| 50 t L / L1 / hole | 360 / 230 / 60 mm | Confirm plate and attachment ratings together. |
| 100 t L / L1 / hole | 570 / 360 / 96 mm | Reserve space for the complete connected assembly. |
| Temperature / protection | -20 to +70 deg C / IP66 | Confirm the ordered steel version and field connections. |
Keep the higher-load envelope in the installation review
The 25-30 t reference uses 320 mm length, 200 mm centres and 50 mm end holes. At 50 t these become 360, 230 and 60 mm; at 100 t they are 570, 360 and 96 mm. Include plate thickness, adjacent fittings, cable access and inspection space before reserving the installed span. Do not assume the offered sensor, pins and clevises are supplied as one complete approved package unless the quotation and drawings establish that scope.
Calibrate the complete tensile measuring channel
The rated-output entry is 1.5-2.0 mV/V with a listed +/-0.05 mV/V tolerance; confirm the actual offered sensitivity rather than assigning it from capacity. Input resistance is 380 +/-30 ohms and output resistance 350 +/-5 ohms. Use 5-12 V DC bridge excitation and confirm the termination of the listed 3 m cable. Apply agreed reference tension through the final pins and check repeat readings and return after release. Nonlinearity is listed as +/-0.05-0.1% FS, not a complete assembly error limit.
For 1-3 t where a shorter link is needed, compare MV-LC0133 with its different centres, plate thickness and end-hole dimensions.
Clevis clearance and the complete load link
Q1. Can the 5-8 t part fit where a 1-3 t part was installed?
The published length, pin centres and holes match, but plate thickness increases by 10 mm. Check clevis width, retaining hardware and articulation before accepting the change. The adjoining structure also needs assessment for any higher working load.
Q2. Does 150% safe overload define a lifting working-load limit?
That sensor entry does not establish the rating or approval of the complete lifting assembly. Obtain the required structural and application documents for the offered sensor and attachments. Do not use it as a recommended operating load or an automatic alarm setting.
