Suggested Mounting

Customers who bought this load cell also bought:

UX-100 USB extender cables for 15 additional feet from the DI-100U or DI-1000U USB load cell interface
Optional USB Relays that can be programmed to open or close based on force input from load cell to PC
Optional LoadVUE load cell software to display, log and plot the force data from USB load cells

Tank Weight Measurement

If you need to measure the weight of a tank and its contents for process control applications, we can provide weigh modules that are built using these RAP4 load cells as shown below.

You can easily attach these factory calibrated digital weigh modules to the feet of a tank and display and monitor weights effortlessly on a PC! Take a look at our four weigh module kit which includes everything you'd need to get started.

Weight Measurement Sensor for Health Kiosk

RAP3 Single Point Load Cell

		Precise Non-Linearity from 0.02% of full scale.
		Rugged Aluminum construction.

These single point load cells are excellent for floor scales used to weigh patients or in health kiosks. You can use a single load cell to construct a 20" x 15" USB scale when combined with our DI-100U USB Load Cell interface. This load cell has excellent off center loading compensation and can handle significant side loads and have very good accuracy, stability and easy mounting features.

They are available in 750 Kg capacity. Dimensions: 6.86" x 2.36" x 2.56". For other capacities, please take a look at the RAP4 load cells which are identical in every respect except they are half the height of the RAP3 load cells and are available in 50 kg, 250 kg and 300 kg capacities.

USB Load Cell Configuration

RAP3 Universal Load Cell Configuration

One RAP3 single point load cell
One DI-1000U 24-bit digital load cell interface
Single-channel LV-1000 LoadVUE Pro software

Simply connect the load cell to the DI-1000U Digital Load Cell Interface & use the USB out port on the DI-1000 to connect to a PC via the USB port. The DI-1000U is a signal conditioner and 24-bit digitizer and handles all the communications functions to talk with USB port of a PC. When connected this way, the load cell appears on the PC as a virtual COM port. Using a standard terminal emulator you can send commands to the sensor to display loads on screen. They can either be one at a time or in continuous operation mode. You can also use Matlab, LabView or other popular programs to communicate and get calibrated readings from the load cell. Alternatively, use our application (LoadVUE) to display, log or plot load measurements on a PC.

If you do not need the very high precision of the DI-1000U, you can use our DI-100U digital load cell interface with 16 bit ADCs and Serial TTL or USB output. The DI-100U is sufficient for accuracies of +/- 0.1% of full scale output. Or in other words if you need to measure +/- 1 lb accuracy over 1000 lb range or +/- 0.1 lb accuracy over 100 lb range, then the DI-100U is more than adequate for your application.

Some users want a high level 0-5V analog DC output in order to work with existing data acquisition systems or PLCs. Ih that case, you can use this load cell with our AI-1000 Load Cell interface which provides an amplified 0.5 to 4.5V output proportional to the applied loads. We can provide the system together with calibration and the formula to convert from voltage to loads/forces when ordered in this configuration.

Application Development

If you are looking to develop your own custom software application, our digital USB load cells and wireless load cell interfaces offer convenient ASCII commands to obtain load information directly from the interfaces/load cells without need for any signal conditioning or data processing. With just a few commands you'll be able to incorporate load/force/weight information into your application. You can also use Visual Basic, Visual C++, Matlab, LABView or any other application development environment to create your custom applications with our interface/load cells.

See our support pages for details.

You can access Sample Code for Visual Basic, Matlab, Python, Arduino and customize it for your own needs.
