MV-LC0143 Side-Entry Oilfield Load Cell, 10-20 t

METRAVON MV-LC0143 is a side-entry oilfield load cell with a twin-column measuring arrangement for pumpjack systems. The family is listed at 10-20 t. The open-side geometry changes installation access, but does not remove the need to review the load contacts, central-member clearance and the site procedure for supporting the load before installation or removal.

Review side-entry oilfield load cell clearance and contact seating

The reference drawing includes a 41 mm slot-width callout and a 49 mm circular-clearance detail. Compare both features with the central member and the full load stack; do not treat them as interchangeable bore diameters. Check how the upper and lower parts seat on the measuring contacts, and identify the bracket configuration in the offered drawing. A twin-column arrangement does not establish an unlimited tolerance for eccentric loading or contact on only one side.

Separate access geometry from a safe installation method

Side access is not permission to insert or remove the sensor under a supported operating load. The site must use its approved isolation and independent load-support procedure with qualified personnel. Provide the available access, adjacent clamps and required maintenance clearance for review. After installation, inspect the final seating and unloaded reference condition, then verify known or agreed reference loads before the recorded operating signal is accepted.

Name the delivered signal package on the order

The sensor specification gives 1.0-1.5 mV/V sensitivity with +/-0.05 mV/V tolerance, a 750 +/-30 ohm input and 700 +/-5 ohm output. Excitation is 5-12 V DC and a 3 m cable is listed. Current, voltage or wireless transmission requires a confirmed conditioning or transmission arrangement; no particular output range, radio protocol or power system is established by the bridge specification. Identify each component and its data connection to the RTU or logger.

Check the force record through a representative cycle

Agree the operating force range, required recording interval and any stroke-position reference. Confirm zero, reference-load scaling and the behaviour of the complete channel after the final seating and cable route are established. Repeatability is listed as +/-0.2% FS and creep as +/-0.1% FS, without a stated creep duration. Nonlinearity is +/-0.3-0.5% FS. Use the offered performance and agreed verification method rather than describing these separate entries as a single system-accuracy guarantee.
