A USB tension load cell is a force sensor that measures tensile forces and transmits data to a computer or other device via a USB connection[1][9]. Unlike traditional load cells, which require additional signal conditioners and data acquisition systems, USB load cells have built-in electronics that simplify the measurement process[1]. This makes them easier to use and more cost-effective for a variety of applications[1].
Traditional load cells typically consist of strain gauges arranged in a Wheatstone bridge configuration, outputting a millivolt signal proportional to the applied force[1]. To use these load cells, one would typically need a 10V DC power supply, a signal conditioner to amplify the signal, a data acquisition system to digitize the signal, and application software like LabVIEW to view and process the signal[1].
USB tension load cells streamline this process by integrating the necessary electronics into the sensor itself[1]. These load cells are powered via the USB port and can communicate directly with a computer, tablet, or Raspberry Pi[1]. This integration eliminates the need for external power supplies, signal conditioners, and data acquisition systems, making the setup process quicker and less expensive[1].
There are generally two types of USB load cells:
- Capacitive Load Cells: These load cells use capacitive sensing technology, where changes in capacitance due to applied force are measured[1]. An example is the iLoad series from Loadstar Sensors, which have integrated electronics that convert the load into a frequency and then into a calibrated force/load/weight reading on a PC or microcontroller without the need for additional signal conditioners or special software[1].
- Resistive Load Cells with Interface: Traditional resistive load cells can also be used as USB load cells when connected to a digital load cell interface (e.g., DI-100U or DI-1000U from Loadstar Sensors)[1]. These interfaces provide a digital output via USB (or UART) to connect to a PC or microcontroller[1].
USB tension load cells offer several advantages over traditional load cells:
- Simplified Setup: The integrated design eliminates the need for external power supplies, signal conditioners, and data acquisition systems[1].
- Cost-Effectiveness: By reducing the number of components required, USB load cells can be a more affordable solution[1].
- Ease of Use: USB load cells are easier to set up and use, with plug-and-play functionality and accompanying software for data analysis[1][5].
- Direct Data Acquisition: The USB interface allows for direct connection to computers and other devices, simplifying data acquisition and analysis[9].
One of the key considerations when using a USB tension load cell is software compatibility[1]. The software used must be able to communicate with the load cell, acquire data, and display or log the measurements[1]. Several software options are available, each with its own features and capabilities[1].
LoadVUE Pro is a software application developed by Loadstar Sensors for use with their USB load cells[1]. It allows users to display, log, and plot data on a PC or tablet[1]. LoadVUE Pro is designed to work seamlessly with Loadstar Sensors' iLoad series digital load cells and resistive load cells connected to digital load cell interfaces[1].
Key features of LoadVUE Pro include:
- Data Display: Real-time display of force measurements[1].
- Data Logging: Ability to log data for later analysis[1].
- Data Plotting: Graphical representation of data[1].
- Customization: User-configurable settings for data acquisition and display[1].
SensorVUE is another software option from Loadstar Sensors that is compatible with their USB load cells[1]. Like LoadVUE Pro, it allows users to display, log, and plot data on a PC or tablet[1]. SensorVUE may offer additional features or a different user interface compared to LoadVUE Pro[1].
ControlVUE is also compatible with Loadstar Sensors' USB load cells[1]. It provides similar functionality to LoadVUE Pro and SensorVUE, with the ability to display, log, and plot data[1]. ControlVUE may be tailored for specific applications or industries[1].
LoadVUE Lite is a simplified version of LoadVUE Pro, offering basic data acquisition and display capabilities[1]. It is a good option for users who need a straightforward solution without the advanced features of the Pro version[1].
LV-1000HS-10K is another software option compatible with Loadstar Sensors' USB load cells[1]. Specific details about its features and capabilities may be available on the Loadstar Sensors website[1].
WinCT-DLC is a free software provided by A&D for use with their LC1205-USB S-Type Load Cell with USB Output[7]. This software streamlines the process of connecting the load cell to a PC, allowing users to measure and log data[7].
Key features of WinCT-DLC include:
- Easy PC Connection: Simple setup for connecting the load cell to a computer[7].
- Measurement and Logging: Ability to measure and log force data[7].
- User-Friendly Interface: Designed for ease of use, even for users without indicator expertise[7].
The DSC Toolkit is a load cell software that allows users to save setup and calibration data to a PC[4]. This makes it easy to switch from one load cell to the next using the same DSCUSB interface[4].
LabVIEW is a graphical programming environment that is often used for data acquisition and instrument control[1]. While USB load cells are designed to simplify the measurement process, LabVIEW can still be used to create custom applications for advanced data analysis and control[1].
MATLAB is a high-level programming language and environment that is widely used in engineering and science[1]. It provides powerful tools for data analysis, visualization, and algorithm development[1]. Like LabVIEW, MATLAB can be used to create custom applications for use with USB load cells[1].
In addition to the software options listed above, other programs can be used to communicate with USB load cells[1]. A standard terminal emulator can be used to send commands to the sensor and display loads on screen[1]. Visual Basic, Visual C++, Python, and Arduino can also be used to create custom applications[1].
The choice of software will depend on the specific application and the features required[1]. Consider the following factors when selecting software for a USB tension load cell:
- Compatibility: Ensure that the software is compatible with the specific USB load cell being used[1].
- Features: Determine the required features, such as data display, logging, plotting, and analysis[1].
- Ease of Use: Choose software that is easy to use and configure[1].
- Customization: If custom applications are needed, select software that allows for customization[1].
- Cost: Consider the cost of the software, as some options are free while others require a license[7][4].
For users who want to develop their own custom software applications, digital USB load cells and wireless load cell interfaces offer convenient ASCII commands to obtain load information directly from the interfaces/load cells without the need for signal conditioning or data processing[1]. With just a few commands, users can incorporate load/force/weight information into their applications[1].
Loadstar Sensors provides sample code for Visual Basic, MATLAB, Python, and Arduino, which can be customized for specific needs[1].
To use multiple USB load cells simultaneously, connect each load cell to a separate USB port on the computer[1]. If there are not enough USB ports, a USB hub can be used[1][4]. Make sure that the software being used supports multiple load cells[4].
USB tension load cells are used in a wide range of applications across various industries[9]:
- Industrial Automation: Monitoring forces in real-time for predictive maintenance, quality control, and process optimization[9].
- Medical Devices: Integrating load cells into medical equipment like scales and force-measuring instruments for accurate and reliable data[9].
- Research and Development: Facilitating precise force measurements for experiments and data collection in laboratories and research facilities[9].
Digital calibration between the sensor and interface pair is necessary for digital USB output[1]. Ensure that the load cell and interface are properly calibrated for accurate measurements[1].
Several popular USB load cell kits are available that include a load cell, digital load cell interface, and software[1]:
- RSB2 Button Load Cell Kit
- RSB6 Pancake Load Cell Kit
- RAS1 S-Beam Load Cell Kit
- iLoad Mini Load Cell Kit
These kits provide a convenient way to get started with USB load cells[1].
