Recommended Maximum Force
| Sensor | Max. Force | Max. Force |
| (High Gain) | (Low Gain) |
| Sensor | Max. Force | Max. Force |
|---|
| B201 - L | 0 - 1 lb. (4.4 N) | 0 - 25 lbs. (111 N) |
| B201 - M | 0 - 25 lbs. (111 N) | 0 - 150 lbs. (667 N) |
| B201 - H | 0 - 150 lbs. (667 N) | 1 - 1000 lbs. (4448 N) |
(Adjustable gain feature of the ELF System allows you to set force ranges)
Typical Performance
Linearity (Error): < ±3% (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% / logarithmic time (Constant Load of 90% sensor rating)
Response Time: < 5 µsec (Time required for the sensor to respond to an input force; Impact load - recorded on Oscilloscope)
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)
ELF Data Acquisition Electronics
Residing within the plastic ELF handle is the data acquisition hardware with USB connection. This patented interface
ensures optimal performance of our FlexiForce sensors. The simple insertion of a FlexiForce
sensor yields a powerful measurement tool.
Our patented electronics allow you to optimize the performance of the ELF system over a selected
force/load range. The electronics adjust the device sensitivity to best fit the dynamic range of the specific
application. This allows you to "fine tune" our single element sensors for optimal performance. Designed
to be user friendly, simple calibration procedures can deliver accuracies of + 5%. More controlled procedures
can reach an accuracy level of + 3%. The ELF's innovative electronics provide high quality signals at
distances of up to 30 feet from the PC.
