Recommended Maximum Force
Adjustable gain feature of the ELF System allows the customer to set force ranges.
| Sensor | Max. Force (High Gain) | Max. Force (Low Gain) |
| B201 - L | 0 - 1 lb. (4.4 N) | 0 - 25 lb. (111 N) |
| B201 - M | 0 - 25 lb. (111 N) | 0 - 150 lb. (667 N) |
| B201 - H | 0 - 150 lb. (667 N) | 0 - 1000 lb. (4400 N) |
Typical Performance
| Evaluation Conditions | ||
| 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 | < 3%/logarithmic time | Constant Load - 25 lb. (111 N) |
| Response Time | < 5 µsec | 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)
