Haibosensor manufactures the 3kg load cell for a variety of weighing and force measurement applications. We offer different types of load cells, including single-point and bending beam designs, and manufacture strain gauges in-house to support diverse application requirements.
In addition to our standard 3kg load cell, we provide custom load cell solutions tailored to your requirements, including dimensions, materials, ingress protection ratings, and more. Our engineering and quality control teams also provide product testing, calibration, and technical support to help meet your equipment requirements.
Weighing equipment varies in structural design, available mounting space, and measurement requirements, making it important to select the right load cell configuration. Common 3kg load cell designs include single-point, bending beam, S-type, and button-type compression load cells to support different weighing and force measurement applications. As a load cell manufacturer, we also offer customization services to meet specific equipment requirements. Options may include overall dimensions, height, mounting hole positions, and other mechanical interfaces, helping you find a suitable load cell solution for your equipment.
A single-point 3kg load cell is designed for platform weighing and provides off-center load compensation. A single sensor can typically support an entire weighing platform while helping maintain consistent measurements at different loading positions.
A bending beam load cell features a relatively simple structural design that can help control manufacturing costs. Some models offer a low-profile design for equipment with limited installation space.
An S-type 3kg load cell measures both tension and compression. Its threaded mounting points allow convenient installation in force testing and other suitable measurement systems. Custom configurations may be available for specific application requirements.
A button-type compression load cell is designed for axial force measurement in compact spaces. Its low-profile form can suit applications such as actuator testing and other compression force measurement systems. A custom 3kg configuration may be available depending on mounting and performance requirements.
Our 3kg load cells are available in both standard and customized configurations. The table below lists the key specifications of standard model HBTLSW05 for reference. Customized versions can be adjusted in dimensions, cable configuration, output signal, and protection class to meet application requirements, and specific parameters may differ from the standard model. For configurations tailored to your working conditions, please contact our engineering team.

From kitchen scales and coffee machines to smart pet feeders and industrial weighing systems, a 3kg load cell supports a wide range of low-capacity weighing applications. It helps equipment manufacturers integrate weight measurement into consumer appliances, commercial scales, and compact filling systems.
A 3kg load cell is suitable for various small weighing devices, including kitchen scales and food scales. These devices help users weigh ingredients such as rice, measure food portions, and manage portion sizes for nutritional planning.
A 3kg load cell can be used in coffee machines to monitor coffee bean levels, measure ground coffee doses, and weigh brewed coffee. In smart appliances such as smart pet feeders, it also helps monitor remaining pet food and control portion dispensing, supporting more precise ingredient management and automated feeding.
In low-capacity retail scales and portion weighing devices, a 3kg load cell measures items such as fresh produce, bulk goods, deli meats, and cheese. In commercial food preparation, it also supports meal portioning and portion control, helping improve weighing accuracy and operational efficiency.
In compact industrial weighing and filling systems, a 3kg load cell supports small-quantity weighing and dispensing in packaging machines, dosing systems, and filling scales. In in-line checkweighing systems, it measures product weight on a conveyor, allowing the control system to identify out-of-range products and trigger automatic rejection.
Our 3kg load cell support customization to meet different application and equipment requirements. Options include materials, cables and connectors, protection ratings, mounting dimensions, packaging, high-temperature strain gauges, and signal output configurations. Contact us to discuss your project requirements and find a suitable solution.
Aluminum alloy is the mainstream material for 3kg load cell—adequate structural strength, lightweight, and easy to machine. Stainless steel is also available for special environments.
Our 3kg load cell use a standard 4-wire load cell interface. Cable length, diameter, and type (including high-temperature cable) are customizable. Waterproof junction boxes and aviation connectors ensure a reliable 4-wire load cell connection.
Termination options include JST, ZH, PH2.0, and PH2.54 connectors in 3P and 4P configurations, enabling fast and compatible load cell connection to your equipment.
IP65 protection is available for dust and water-jet resistance. Additional sealing and protective coatings can help protect the strain gauge in humid environments. Oil resistance can be customized based on application requirements.
For 3kg load cell mounting, overall dimensions, height, diameter, mounting hole positions, and threaded hole specifications (such as M4 and M6) can all be adjusted to match your equipment structure.
For 3kg load cell operating at high temperatures such as 150°C or 200°C, just tell us your temperature range. Our engineers will select the right strain gauge for your custom load cell to improve stability and service life.
