Product catalog summary

Overview

This document provides detailed technical information on small-sized compression and tension/compression load cells, specifically the LCN-A and LUX-B series. It covers specifications, mechanical and electrical properties, installation accessories, and safe usage guidelines.

1. Product Description

The LCN-A series consists of compact, lightweight, stainless steel compression load cells with hermetically sealed structures filled with inert gas for stable and reliable performance. These load cells are corrosion-resistant and suitable for installation in existing facilities. TEDS-installed versions are available upon request.

The LUX-B series includes compact tension/compression load cells designed for low capacity measurements, with various mounting accessories to facilitate installation and ensure measurement accuracy.

3. Dimensions and Accessories

Detailed dimensional drawings are provided for the LCN-A series and its accessories, including saddles (CA-2F, CA-2B), mount bases (CF-42 and variants), and inner plates (CAI-2) designed to protect the load sensing part from impact damage.

Mounting hardware such as hexagon socket head bolts and locking pins are included with mount bases. Accessories enable compatibility with other load cell models (e.g., LCF-A) and facilitate secure installation.

4. Safe Usage Guidelines

To ensure safe operation, the material to which the load cell is mounted must have sufficient tensile strength (σb ≥ 800 N/mm²) for load cells rated 2 kN or higher. Recommended materials include SUS 630 (H900, HRC 40-47) and SCM 434 (HRC 30-38).

For tension load measurements, users must avoid exceeding the safe overload rating. Specific mounting accessories and patches are recommended to prevent damage and ensure measurement integrity.

5. Safe Bending Moment and Lateral Load

The document includes graphs and formulas to calculate the safe bending moment and safe lateral load for the LUX-B series load cells under lateral loads applied in the sensitivity direction. The safe bending moment (M) relates to the safe lateral load (f) and the distance from the center of moment (L) by the formula: M = f × L.

Example calculations demonstrate how to determine the maximum allowable lateral load to avoid mechanical damage, noting that these limits ensure mechanical safety but do not guarantee measurement accuracy.

6. Additional Notes

Hermetically sealed stainless steel construction ensures corrosion resistance and stable performance.
TEDS (Transducer Electronic Data Sheet) versions are available for easier integration.
Accessories such as ball joints, whirl-stop couplings, and brackets are available to reduce measurement errors caused by misalignment or vibration.
Protection ratings and environmental capabilities make these load cells suitable for harsh industrial environments.

■Configurations of Strain Column Strain gage Strain gage mechanical strength may arise depending on the installation method. For solutions of such a problem, please contact us . When attaching the rotating attachment in the RJ-B series to the load cell, remove the coupling screw of the load cell. Then screw the rotating attachment with a proper tightening torque shown on the table above. . When screwing a ball joint into the load cell, take care not to apply an excess torque to the load cell. Especially, a small-capacity load cell may be damaged by an excess torque.

To obtain a correct value by using a transducer and a measuring instrument, the measuring instrument should be adjusted based on calibration data of the transducer. Conventionally, such adjustment has been done manually. TEDS-installed transducers have their own information saved in memory to let TEDS-compatible instrument read the data for automatic adjustment, thereby contributing to time and labor savings and prevention of erroneous setting. ■ Relation between Strain and Voltage in Transducer Outputs The output of a strain gage transducer is expressed in either strain (|im/m) or voltage (mV/V...

■ Installation of Load Cell to Hopper or Tank Usually, it Is desirable that a total weight Including the tare weight of hopper or tank Is evenly loaded onto each load cell. If the loading point moves and the centroid is not fixed, estimate the locus of the centroid and referring to the typical position, arrange each load cell so that a maximum load is evenly imposed on each load cell. Also, select load cells of which the rated capacity is sufficient enough to cover the expected maximum load. There may be two installation methods: standard and simplified. With the standard method, a load is wholly...
