How to Build a Scale

 
 

RAPG Low Profile Load Cell
precise load cell Precise
Non-Linearity from 0.05% of full scale.
rugged load cell Rugged Stainless Steel construction.
These low profile load cells are excellent for small precision scales. You can use this low profile load cell to construct a 6" x 6" USB scale when combined with our DI-100U or DI-1000U USB Load Cell interface. To make a wireless scale use a DI-1000ZP wireless 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 100 g, 300 g, 1 kg, 2 kg and 3 kg. capacities. Dimensions: 70 mm x 15 mm x 22 mm. Larger capacities are available in larger sizes.
You can see a video of a 6"x6" USB Scale with sub gram accuracy built using a 1 kg version of the RAPG load cell by clicking on the play button below.

USB Load Cell Configuration

RAPG Universal Load Cell Configuration
  • One RAPG low profile load cell
  • One DI-1000U 24-bit digital load cell interface
  • Single-channel LV-1000 LoadVUE Pro software
   Buy RAPG USB load cell kit

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.

RAPG Universal Load Cell Configuration
  • One RAPG low profile load cell
  • One DI-1000ZP wireless digital load cell interface
  • Single-channel LV-1000 LoadVUE Pro software
   Buy RAPG Wireless load cell kit

You can use this load cell wirelessly by connecting it to our DI-1000ZP wireless load cell interface. This configuration allows you to wirelessly connect to a Windows/Unix/Mac computer. On a Windows platform, you can use our LV-1000 LoadVUE Pro software to display, log and plot force vs time data effortlessly.



Analog load cell configuration

RAPG Universal Load Cell Configuration

  • One RAPG low profile load cell
  • One AI-1000 0-5V DC load cell interface
   Buy RAPG Analog load cell kit

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.
