MV-LC0114 Miniature Tension and Compression Load Cell, 5-100 kg

METRAVON MV-LC0114 is a miniature tension and compression load cell for space-limited assembly-force, button-feel and robotic gripping fixtures. Two axial studs carry force through a stainless-steel diaphragm body. The documented ratings are 5, 10, 20, 30, 50 and 100 kg. Select the stud size and fixture geometry alongside the force interval; the round body diameter alone does not establish a suitable fit.

Connect the miniature tension and compression load cell without winding up the body

The reference body diameter is 25.4 mm, with a 13 mm body-height designation and 37 mm overall length including the opposed studs. The 5-30 kg rows use M5 threads; 50 and 100 kg use M6. Include couplings and locking access in the installed length. Specify thread engagement and any joint movement from the assembly drawing. Do not use the cable to restrain the body or force an offset linkage into alignment by tightening a stud.

Keep sensitivity tolerance separate from force accuracy

Rated output is 1.5 mV/V with a +/-10% tolerance. That is a sensitivity tolerance, not a +/-10% measurement-accuracy claim, and it is not the +/-0.05 mV/V tolerance listed for some larger sensors. Obtain the actual rated output for the delivered unit and establish span through the final fixture. The specified nonlinearity and hysteresis are each +/-0.5% FS, with +/-0.3% FS repeatability. Calibration does not remove all effects of an unsuitable force path or turn these entries into a tighter system guarantee.

Evaluate the force cycle used for the assembly decision

For a push-pull test, identify the required sign, preload, loading direction, reversals and force points used for pass or fail. Apply suitable tensile and compressive references where both directions are needed, and check the indication after release. If a button test needs force against travel, specify displacement acquisition and synchronisation separately; this bridge does not supply a displacement channel. No sampling rate, bandwidth or gripping safety function is established by the compact form.

Route the cable before checking the smallest force

The bridge requires 5-12 V DC excitation and lists 1000 +/-30 ohms input resistance and 1000 +/-5 ohms output resistance. Its cable is 3 m long and 3 mm in diameter. Secure the cable so it cannot pull on the miniature fixture during travel, then check low-force stability with the final reader and motion equipment operating. Working temperature is -20 to +70 deg C and housing protection is IP66. Include fixture heating and cable movement in the test conditions rather than relying only on a stationary bench result.

For a fixture that applies compression through a small top button instead of opposed studs, compare the different mounting arrangement of MV-LC0116.
