Product Introduction
-
The Single Point Load Cell is a high-precision force sensor designed specifically for applications requiring weight sensing at a single point, such as platform scales and bench scales.Renowned for its unique mechanical design, it effectively compensates for off-center load errors, ensuring highly accurate and consistent results regardless of where an object is placed on the scale.
-
This "single-point" capability significantly simplifies scale design, with only a single load cell typically required to support the entire platform. Manufactured from robust alloy steel and featuring precise temperature compensation, the sensor delivers reliable performance. With a high IP67 protection rating, this single point load cell is the trusted core component for various scales used in retail, industrial production, logistics, and warehousing.

Application
The Single Point Load Cell is the preferred solution for applications requiring high accuracy from a single sensing point. Its unique ability to compensate for off-center loads makes it incredibly versatile across numerous industries.
Retail & Industrial Weighing Platforms
This is the most classic application, where the sensor serves as the core of various platform scales. Specific uses include: price-computing retail scales, industrial counting scales, checkweighing scales, kitchen scales, bench scales, and various floor scales.
Automated Production & Process Control
Used in automated batching systems, packaging machine fill level control, in-line product weight detection and sorting, and packaging machinery for precise filling control.
Logistics, Warehousing & Distribution
It is integrated into: warehouse storage racks, portable weighing platforms for inventory management, mail and parcel sorting scales.
Food, Pharmaceutical & Chemical Industries
Suitable for occasions with high hygiene requirements (optional stainless steel material or special surface treatment), used for raw material feeding, process control and finished product packaging.
Agriculture & Animal Husbandry
Animal weighing scales for monitoring livestock health, feed dispensing systems, hopper and silo level monitoring, and portable crop yield scales.
Kind Tips
·Proper Installation and Leveling
Ensure the load cell is mounted on a level, rigid base. The weighing platform itself must possess sufficient stiffness, and connecting components (such as support pillars) must ensure stable contact with the load cell to avoid measurement errors caused by platform deformation or uneven installation.
·Avoid Non-Axial Force Interference
Although single-point load cells offer excellent off-center load compensation, the platform design should prevent strong lateral forces, torsion, or shock impacts, which can affect accuracy and potentially damage the sensor.
Electrical Connection and Safety
·Use the manufacturer-recommended wiring diagram (typically 4-wire or 6-wire). Employ shielded cables with reliable single-point grounding to effectively suppress electromagnetic interference. Secure the cables properly to prevent movement.
Environmental Considerations
·Despite an IP67 protection rating, prolonged immersion in water or exposure to highly corrosive environments should be avoided. Operate within the compensated temperature range (-10°C to 60°C), as extreme temperatures may affect performance.
Regular Maintenance and Calibration
·Periodically inspect the load cell and weighing platform for mechanical damage or debris accumulation. To ensure long-term weighing accuracy and compliance, regular calibration by qualified technical personnel is recommended.
FAQ
Q: What are the main advantages of single point load cell?
A: Its unique design provides excellent off-center load compensation, ensuring high accuracy even when weight is applied unevenly on the platform, simplifying scale structure with a single sensor.
Q: How do I select the right capacity for my application?
A: We recommend selecting a range where the maximum expected load is between 50-80% of the sensor's rated capacity. This ensures optimal accuracy and prevents overloading. Our engineers can provide free guidance on your selection.
Q: How to install the sensor correctly?
A: Ensure the mounting surface is flat and rigid, and avoid lateral forces or torsion. Use the recommended fasteners and torque to maintain alignment and accuracy.
Q: What is your quality guarantee?
A: The single point load cell has a one-year warranty. During this period, we will repair or replace any product quality issues and provide ongoing strong technical support.
