Hydraulic Shear Pin Load Cell for Crane
The product is described as a DIY electrical load cell designed for force measurement. Best for hands-on mechanics or crane operators who want a straightforward, install-it-yourself solution. The geometry of a shear pin design suits temporary or semi-permanent weighing tasks in lifting operations. Consider this option if you need a compact sensor with simple wiring and easy replacement in field conditions. A potential limitation is that detailed specifications on torque rating or overload health are not provided in the listing, so verify compatibility with your system before purchase.
Industrial Pulley Drawing Weighing Sensor 2-100T (10T)
Best for high-capacity weighing where precision is critical. This sensor uses a strain gauge design and offers 0.5% full-scale accuracy, with ranges from 2T up to 100T. It is built from alloy steel and includes an overload margin up to 300% F.S, which supports rugged environments. Choose this when lifting tasks require a robust sensor with wide capacity options. A limitation is that the product cover does not specify environmental ratings (water or dust ingress), so ensure it matches your installation conditions.
Load Cell 2-100T Double Ended Shear Axle Pin Type (3T)
Best for projects needing a pin-type load cell with high precision across multiple ranges. It mirrors the 2-100T range and 0-2T, 0-5T, up to 0-100T options. This makes it versatile for varied lifting applications. It is described as robust and alloy-steel constructed, offering reliable performance in demanding conditions. The listing does not reveal specific installation footprints or electrical connection standards, so verify compatibility with your data acquisition system.
Superhao Quick Release Pin 40 PCS
Best for marine and outdoor fastening where fast, secure pin connections are needed. Features include solid metal construction for rugged use, a one-hand spring-loaded locking mechanism, and a built-in split ring to keep the pin attached to gear. This makes it ideal for temporary assemblies and equipment that requires quick disassembly. A caveat is that this is a quick-release pin system, not a full-load cell sensor; it should be used in conjunction with a load cell where appropriate, and not as a sole load-measuring device for critical loads.
Load Cell 2-100T, 3T Variant (Pulley Drawing Weighing Sensor)
Best for flexible testing setups where 3T is a preferred intermediate capacity. It features a high-precision strain gauge design and 0.5% F.S accuracy, with the same broad 2-100T range and alloy-steel construction as other models in this family. Choose this if you need a narrow 3T option alongside higher-capacity configurations. A potential limitation is that exact safety factors beyond 150% F.S and 300% F.S are not specified in the brief listing.
Customized Pulley Drawing Weighing Sensor 2-100T (3T)
Best for installations requiring 3T in a wider 2-100T line. It shares the same strain-gauge, high-precision design and alloy-steel robustness, with a safe overload margin of 150% F.S and capability to withstand up to 300% F.S. This makes it suitable for repeated load testing and calibration tasks. A caution is that detailed environmental and mounting compatibility aren’t fully disclosed in the listing, so confirm your hardware fit before ordering.
Buying Guide
What capacity do you actually need?
Assess lift heights and maximum expected loads. If you routinely measure heavy material, a 100T or 2000KG-rated option provides margin. For smaller precision tasks, a 2T–5T model may be more cost-effective and easier to install.
Should you prioritize precision or durability?
Precision (0.5% F.S) is common in these options, but durability (alloy steel construction and high overload margins) matters in harsh environments. Choose a design that balances accuracy with resistance to overloads and environmental stress.
What mechanical configuration fits your system?
Double-ended shear axle pin types and pulley-drawing sensors suit different mounting schemes. Pin-type solutions are simple to replace, while pulley-drawing sensors excel in continuous weighing along cable paths. Verify mounting footprint and connection to your data acquisition system.
What environmental conditions must be supported?
Look for IP ratings, dust and water exposure, and temperature tolerance. Several listings emphasize robustness but may not detail ingress protection. If you operate outdoors or in wet zones, confirm protection levels before purchase.
How easy is installation and maintenance?
Some products are designed for DIY electrical installation, while others assume professional mounting. Consider ease of wiring, calibration procedures, and the availability of replacement parts or spokes for field service.
FAQs
- What is a shear pin load cell used for? It measures force by converting mechanical shear or pin displacement into an electrical signal, suitable for lifting and weighing tasks on cranes and pulleys.
- Is 0.5% F.S accuracy common for these sensors? Yes, several models advertise about 0.5% full-scale accuracy, which is typical for industrial pulley and lever load cells.
- Can these sensors be used in outdoor marine environments? Some models are designed for rugged outdoor use, but confirm environmental ratings with the seller before exposing them to water or salt spray.
- Do these products require specialized calibration? Most require standard calibration procedures using known weights, but exact steps depend on the model and system integration.
- What is the advantage of a dual-ended pin type? It simplifies mounting and replacement in tight spaces and can improve alignment in pulley-based setups.
- Are there any limitations to note? Many listings omit detailed specs like exact torque limits, ingress protection, and wiring standards. Always verify compatibility with your application.
