Tekscan FlexiForce WELF
(Wireless Economical Load and Force System)
Wireless ELF is a user-friendly force measurement system, enabling your laptop or PC to quickly capture and store force data from an event up to 200 feet away. This revolutionary system offers greater flexibility for countless applications, including sports equipment testing, safety assessment, medical procedures, industrial R&D, and much more. This system combines FlexiForce sensors with a USB hub, Wireless transmitter, and Windows-compatible software, turning your PC or laptop into a force measurement instrument.
Key software features include:
- Real-time data capture
- Movie recording & saving
- ASCII output to data analysis software
- Simple and storable calibration
- Adjustable sensitivity
- Internal triggering
- Capability to tare a load
- LabVIEW VI Driver Software available

Typical Performance
Linearity (Error): < ±5% (Line drawn from 0 to 50% load)
Repeatability: < ±2.5% of Full Scale (Conditioned sensor, 80% of full force applied)
Hysteresis: < 4.5% of Full Scale (Conditioned sensor, 80% of full force applied)
Drift: < 5% per Logarithmic Time Scale (Constant load of 25 lb (111 N))
Sampling Rate: 200 Hz (Up to eight sensors)
Communication Range: < 200 feet
Battery Life: Approximately 24 hours (Continuous use)
Operating Temperature: 15°F - 140°F (-9°C - 60°C)*
*Force reading change per degree of temperature change = ±0.2%/°F (0.36%/°C)
For loads less than 10 lb, the operating temperature can be increased to 165°F (74°C)
