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)
