MV-LC0121 Canister Compression Load Cell, 10-300 t

METRAVON MV-LC0121 is a canister compression load cell for heavy weighing supports, including vehicle and rail scales, platforms, hoppers and tanks. Its 10-300 t family has four reference body groups. Before choosing a large capacity, compare the required weighing performance with the documented error values and check whether the complete bearing stack fits the available support space.

Decide whether the listed measurement errors suit the job

Nonlinearity is +/-0.3-0.5% FS, hysteresis +/-0.3% FS and repeatability +/-0.2% FS. These entries are not the +/-0.03% FS figures of some other weighing designs. Assess them against the actual working interval and the uncertainty required by the process, using the confirmed offered version. A broad high-load range does not establish high-resolution inventory performance or legal-for-trade suitability. Obtain the necessary complete-system evidence if the result is used for a commercial weighing decision.

METRAVON MV-LC0121 canister compression load cell, 10-300 t — 10-300 t canister compression family; capacity groups change the bearing dimensions, installed height and base fixings.

Compare the canister compression load cell bearing stack by group

The 10-30 t reference is 130 mm high with a 94 mm maximum diameter; the 50-100 t group is 178 mm high and 129 mm in diameter. At 150-200 t these become 220 and 149 mm, and at 250-300 t they become 260 and 184 mm. Add the mating upper and lower parts when assessing installed height. The cap diameter and dome radius also change, so an existing bearing pair cannot be retained on capacity alone.

Item	Value	Selection notes
10-30 t H / maximum diameter	130 / 94 mm	The upper contact diameter is 42 mm.
50-100 t H / maximum diameter	178 / 129 mm	The upper contact diameter increases to 76 mm.
150-200 t H / maximum diameter	220 / 149 mm	Use the 100 mm upper-contact drawing for this group.
250-300 t H / maximum diameter	260 / 184 mm	The upper contact is 120 mm in diameter.
Operating temperature	-20 to +70 deg C	Assess the temperatures of the bearings and reader as well.
Protection / material	IP66 / confirm steel version	Housing protection is not an approval for every application.

Review support forces before accepting the self-aligning description

Document the largest reaction at each support, the centre-of-gravity movement and the way horizontal forces are restrained. Self-alignment and resistance to offset loading are described qualitatively; no numerical tilt or lateral-load envelope is specified here. Assess those limits for the actual bearing assembly. Check that vessel connections and platform stops do not introduce a changing force bypass as the loaded structure moves.

Calibrate the 1.5 mV/V channel with the final support arrangement

This sensor uses 750 +/-30 ohms input resistance and 700 +/-5 ohms output resistance, with 5-12 V DC excitation. Rated sensitivity is 1.5 +/-0.05 mV/V. Check the indicator input, bridge count and the supplied 3 m cable before establishing empty and loaded references. Include loading, unloading and representative dwell conditions in the acceptance plan. The listed +/-0.15% FS creep has no stated duration here; request the relevant conditions for a long-hold process instead of inventing a test period.

Heavy-load capacity and useful weighing performance

Q1. Is this suitable simply because a project needs a 300 t sensor?

The rating is only one requirement. Check the required measurement uncertainty, lowest useful working load, bearing-stack dimensions and actual support reaction. The documented error entries must be acceptable to the project before the larger capacity becomes a useful choice.

Q2. Can the existing cap be reused when changing from 30 t to 100 t?

The reference upper-contact diameter changes from 42 to 76 mm and the dome radius from SR100 to SR200. Height and base dimensions change too. Review both bearing parts and the complete mounting drawing, then recalibrate the assembled support.

Q3. Does a 150% safe-overload value permit routine weighing above capacity?

It is not an extended operating range or a fatigue-life statement. Keep the required working loads within the approved sensor and assembly limits. Include exceptional load events in the mechanical assessment rather than using a safe-overload percentage as a normal process setpoint.
