METRAVON MV-LC0239 is a miniature tension/compression load cell with threaded load connections. Its compact body is suited to assessing axial force in a test fixture or machine linkage where the available mounting space is limited. The two M8 connections define how force enters the sensor; this threaded arrangement requires a different mounting design from a cylindrical sensing pin.
Check the connection geometry before choosing a force range
The drawing shows a nominal 35 x 25 x 12 mm body and two M8 load connections. Allow additional space for the mating fittings, cable exit and adjustment tools. Align the connections so that the intended force passes through the sensor without an imposed bending moment. Obtain the mating-thread and installation details before approving a fixture drawing.
The available ratings are discrete choices: 50, 100, 200 or 500 N, and 1 or 2 kN. Include fixture preload, the largest operating force and credible transients in the selection. The smallest normal reading also matters: a high-capacity version may leave too little useful signal for the force variation the test needs to resolve.
| Item | Listed data | Design check |
|---|---|---|
| Rated force | 50, 100, 200, 500 N; 1, 2 kN | Select one rating against the complete fixture load case and measurement requirement. |
| Nominal sensitivity | 2 mV/V; tolerance +/-10% | Use the delivered calibration value rather than assuming every unit produces exactly the nominal output. |
| Excitation | 5 V reference; 1-15 V operating | Verify the conditioner setting and bridge loading before connecting the sensor. |
| Operating temperature | -10 to +50 deg C | Distinguish this limit from the nominal -10 to +40 deg C temperature range. |
| Construction | Stainless steel; IP66 | Review connector sealing, cable routing and the actual cleaning exposure separately. |
Verify the force reading with the fixture assembled
The output is a low-level bridge signal. Connect it to an instrument that provides suitable excitation, accepts the expected signal and permits calibration in the required force unit. A nominal 2 mV/V bridge excited at 5 V produces about 10 mV at rated force; that calculation describes the electrical span, not the accuracy of the installed test system.
Record the unloaded or preloaded zero, known-force response and return to zero with the final fittings installed. For bidirectional work, include both required load directions in the agreed calibration and acceptance plan. Keep cable restraint from pulling on the sensing body during movement.
Installation questions
Q1. Can this replace a load pin in a clevis?
A clevis pin is selected around bearing positions and shear planes. MV-LC0239 uses threaded axial load connections, so fitting it into that application requires an assessed mechanical redesign. Matching the force rating does not establish an interchangeable installation.
Q2. Can it feed a PLC current or RS485 input directly?
The listed output is mV/V. Where the PLC does not have a suitable bridge measurement module, specify a compatible conditioner or transmitter and its required output. The weighing instrument range provides a starting point for checking excitation, input span and calibration functions.
Q3. Is the 150% safe load limit a permitted test load?
The safe load limit is an overload specification, not an extended calibrated range or a routine proof-test instruction. Establish the normal measuring range and mechanical protection from the approved application design.
