MV-LC0142 Through-Bore Oilfield Load Cell, 10-20 t

METRAVON MV-LC0142 is a through-bore oilfield load cell for pumpjack measurement and control systems in the 10-20 t family. Force is introduced through the annular contact arrangement around the central opening. Select the exact rating and housing drawing with the site load stack, rather than using the family range as evidence that every intermediate rating or mounting variant is available.

Check the through-bore oilfield load cell against the complete contact stack

The reference drawings show a 52 mm central opening, an 88 mm upper flange diameter and an 87 mm height reference. Two outer-housing forms are illustrated, so confirm the offered outline and dimensional endpoints before setting the installed clearance. Submit the rod or central-member dimensions and the upper and lower contact parts. A nominal bore match does not prove that the assembly transfers force correctly or clears moving parts throughout the operating cycle.

Item	Value	Selection notes
Family capacity	10-20 t	Confirm the actual ordered nameplate rating.
Bore / flange reference	52 / 88 mm	Approve the matching housing and contact drawing.
Height reference	87 mm	Check the dimensional endpoints and complete contact stack.
Excitation	5-12 V DC	Use a suitable low-level bridge reader or amplifier.
Bridge input / output	750 +/-30 / 700 +/-5 ohms	Set acquisition gain from the confirmed rated sensitivity.
Listed cable	3 m; 5 mm diameter	Confirm connector, route and field-joint protection.

Define the load record required from the pumpjack

Provide expected minimum and maximum force, operating cycle and the recording purpose. If the project requires force to be related to stroke position, identify the position reference and acquisition timing as well as the load channel. A sensor specification alone does not establish sample rate, synchronisation or the quality of a complete load-versus-position record. Agree reference checks and how the channel can be verified after the mechanical stack is installed.

Specify a bridge acquisition channel, not an assumed current loop

The listed sensitivity is 1.0-1.5 mV/V with a tolerance of +/-0.05 mV/V. Obtain actual rated output and use it for scaling. Input resistance is 750 +/-30 ohms, output resistance 700 +/-5 ohms and excitation 5-12 V DC. The specified cable is 3 m long and 5 mm in diameter. An RTU or PLC expecting 4-20 mA needs suitable conditioning electronics; the raw mV/V bridge is not that interface. Confirm any enclosure or transmitter in the offered scope.

METRAVON MV-LC0142 through-bore oilfield load cell, 10-20 t — 10-20 t oilfield load-cell family with an annular contact arrangement, IP66 housing entry and a listed 3 m cable.

Keep environmental and accuracy requirements separate

Working temperature is -20 to +70 deg C and enclosure protection is listed as IP66. That entry is not evidence of hazardous-area approval; submit any such site requirement for the proposed complete configuration. Nonlinearity is listed as +/-0.3-0.5% FS, hysteresis and repeatability as +/-0.3% FS, and creep as +/-0.2% FS without a stated time. Confirm the offered values and test conditions instead of presenting one figure as overall pumping-system accuracy.

If the site requires side-entry geometry, compare MV-LC0143 using its own slot and contact arrangement rather than treating it as the same housing.

Assembly fit and the recorded force channel

Q1. Does a 52 mm opening prove compatibility with an existing rod assembly?

It checks only one dimension. Compare the moving-member clearance, contact faces, load-stack height and the selected housing form. The accepted drawing and site loading arrangement must agree before the sensor is fitted.

Q2. Is IP66 sufficient evidence for installation in a hazardous area?

It addresses enclosure ingress protection, not the required hazardous-area approval. Identify the site requirement and obtain applicable documents for the complete offered assembly, including any associated electronics. Do not infer approval from the oilfield application name.

Q3. Does the sensor alone provide a load-versus-position record?

It provides a force signal. A complete record also requires suitable acquisition timing and a position reference where the intended analysis uses one. Confirm those functions at system level and verify the resulting record, not only the static display value.
