Mounting Options
The iLoad Pro load cells have threaded mounting holes on each end. One can sandwich the load cell between two plates or attach ropes/cables/hooks using eye bolts or swiveling rod ends. The sensors can be mounted in any orientation. Does not need to be verically mounted. The measured force will be the relative force applied between the two ends of the load cell.


Apply Compression or Push Force. Load Cell attached to a base plate using three screws from below. The load can be applied to the top of the load cell. Use a steel ball to align and center the applied load axially. Do not apply moments. Force should be axially aligned with center of load cell.
Apply Tension or Pull Force. Load Cell attached to a base plate using three screws from below. The load or pull force can be applied to the top of the load cell. Do not apply moments. Force should be axially aligned with center of load cell.
Here's How it Works
Simply connect the digital load cell to a PC via the USB port. The digital load cell appears on the PC as a virtual COM port. The capacitive sensing element transduces a frequency output signal which is then processed to obtain calibrated forces and output via UART/USB. You can use a standard terminal emulator such as Putty, to send commands to the sensor and obtain calibrated forces. Or you can use our LoadVUE program to display, log and plot force data on a PC or Tablet (Win 8/10). This is an excellent moderate accuracy integrated load cell for room temperature applications.

Optional Analog Load Cell Output / Hybrid Analog and Digital Load Cell Output Configuration
Our iLoad Series capacitive load cells can optionally output an Analog 0-5 V DC output from the same sensor! This analog output is in addition to the normal digital Serial TTL or USB output (via S2U Adapter) that is available as a standard feature. If you purchase the optional HX-100 hybrid load cell breakout board, then you can get easy access to the analog as well as the digital output. You can also access the Tx, Rx pins to connect your load cell to an Arduino or other microcontrollers. You can order the optional analog calibration when ordering these digital load cells.

FAQ
The iLoad Pro Load Cell is a Capacitive Load Cell that works on the principle of change of frequency in response to applied loads. It is intergrated with sensing and processing electronics and embedded firmware to apply calibrations and output calibrated force values. It is single body solution with UART and USB (using an S2 adapter) output.
While the iLoad Series load cells can only be used for compression force measurements, the iLoad Pro load cells are designed for tension and/or compression force measurement. They have a threaded hole at the top and three threaded holes on the bottom that makes it easy to attach eye bolts or rod-ends into which hooks or pins can be inserted. The iLoad Pro has a rugged strain relief built in with the output cable that makes it better suited for industrial grade applications.
The accuracy of load cells is divided into non-linearity, hysteresis and non-repeatability each of which is of the order of +/- 0.25% of full scale. The overall accuracy at room temperature with Tare and Read is of the order of +/- 0.25% of full scale. Which means that on a 100 lb load cell the worst accuracy along the entire range of 0 to 100 lbs would be +/- 0.25 lbs. For a 1000 lb load cell it would be within +/- 25 lbs. This assumes axial loads with no moments or side load and steady state room temperature conditions.
The iLoad Pro load cell is NOT waterproof. The sensor is dust proof and can be used in non condensing environments from about 20C to 30C. The sensor is best used in room temperature controlled environments. Not recommended for condensing cold environments where moisture can seep in.
The iLoad Pro does not need any external signal conditioner. The electronics are built into the body of the load cell. You can use an HX-100 HYbrid load cell adapter to make it easy to get the optional analog 0-5 VDC output. If you need a physical display and don't want to use a PC, then simply connect to our DS-3000-Pro touch screen LCD display to show values on a physical display.
We offer free LoadVUE Lite software to display force/weight on a Windows 8/10 PC/Tablet. The LoadVUE Pro software allows you to display, log & plot force/weight data, recalibrate sensors and get remote support. SensorVUE extends support to an unlimited number of sensors as well as all types of sensors we offer. ControlVUE software extends the functionality offered by SensorVUE and adds the ability to control external devices based on sensor values through a USB Relay with one to eight channel. Our sensors and interfaces allow you to write your own code as well! We also offer customization and custom softrware development services to meet your specific needs!
The iLoad Pro load cell typically has a 6 foot cable with an S2U Serial to USB adapter included as part of the purchase. An optional 10 ft cable is available as an option. If you need to extend the cable beyond the 6/10 ft then purchase the UX-100 USB Extender cable. It adds 5m or 15 feet to the cable length. You can daisy chain three of these if needed to add an additional 45 feet to the 6 foot or 10 foot output cable.
Yes. We offer calibration service on new sensor purchases as well as recalibration service for previously purchased sensors. We use NIST traceable reference standards to perform and validate the calibration and provide a free calibration certificate as part of the service. Note that although we are NOT ISO certified, we follow stringent internal quality processes to ensure excellent accuracy traceable to NIST standards.
