Capacitive Load Cells
Loadstar Sensors' award winning capacitive load cells offer unmatched ease of use in a low profile, rugged and integrated package. Our capacitive load cells offer serial, USB as well as Analog (0-5V DC) output without the need for any special signal conditioning equipment.
These sensors are excellent for applications in controlled room temperature conditions such as those available in R & D labs, Universities and test facilities where one needs to do a quick measurement of loads and forces, log data and visualize the data as a force vs. time plot. Our USB or wireless load cells can be used directly with a PC while our analog load cells with 0-5 VDC output are ideal for use with a PLC or existing data acquisition system.

Our capacitive load cells offer unmatched ease of use in a low profile, rugged and integrated package. The base output from our digital load cells (iLoad Series and iLoad Pro Series) and interfaces (DI-100) is Serial TTL (5V level digital output). We then take this base digital output and provide a USB output using our USBA Serial TTL to USB adapter.
This architecture provides flexibility for customers who want to interface with our load cells from microcontrollers via the Serial TTL (UART protocol), while end users who want high level digital output can easily do so with standard USB or Wireless protocols. When a user requests analog output, we provide a Hybrid adapter (HX-100) using which the user can obtain BOTH digital USB and Analog 0-5 VDC output.
Our capacitive sensors are appropriate for steady state room temperature conditions where one needs to do quick measurements with a Tare. If you need to perform long term measurements under varying temperature conditions, then we suggest you take a look at our offering of resistive strain gauge load cells which offer excellent temperature compensation from -10C to 40C and offers accuracies to +/- 0.02% of full scale loads.

iLoad Pro Industrial Grade Digital Load Cell
The iLoad Pro Series digital USB load cells are designed with better strain relief features for improved ruggedness over the iLoad Series. These Serial TTL(UART) or USB Load Cells are designed for use in industrial environments and are available in capacities up to 10,000 pounds. These USB Load. For more information see our iLoad Pro Industrial Grade Digital Load Cell
iLoad TR Series Tilt Resistant USB Load Cell
These fully integrated digital load cells (USB load cells) (3" dia. and 1.2" high), are designed for applications requiring reduced sensitivity to off-center loading. It comes in capacities up to 100 lbs and accuracies up to +/- 0.25% of full scale. These sensors offer a threaded hole on the top. For more information see our iLoad TR Series Tilt Resistant USB Load Cell
Low Profile USB Load Cell - iLoad Series Compression Only
The iLoad low profile digital load cells offer direct measurement of loads via the USB port of a PC. No need for signal conditioners, data acquisition systems or special software. Just connect and start measuring! These USB load cells are 3" in Diameter and about 0.5" high and meant for. For more information see our Low Profile USB Load Cell - iLoad Series Compression Only
Miniature Load Cell - iLoad Mini
The iLoad Mini miniature load cells are designed for applications where size is a major constraint. The iLoad Mini is only 1.25" in diameter and outputs a 5V TTL square wave whose frequency is proportional to applied loads. When used with the DQ-1000U or DQ-1000A a user can conveniently get either. For more information see our Miniature Load Cell - iLoad Mini
Miniature Load Cell - iLoad Mini Pro Stainless Steel
Available in 500, 1000, 2500, 5000 and 10000 lb capacity. Just two inches in diameter. For more information see our Miniature Load Cell - iLoad Mini Pro Stainless Steel
