For position/displacement measurements that require very precise readings, Lion Precision’s CPL490 Capacitive Displacement Sensor could be the answer. The precision device measures position/displacement with 50 picometer precision or less. This means that the sensor can measure changes in an object’s position when it moves less than the diameter of one of the molecules without filtering out high frequency components out of the measurement signal.
While objects are moving at 15 kHz, the CPL490 can resolve target position changes of less than 100 pm. When the bandwidth is increased to 50 kHz, the precision is still less than 0.3 nanometers.
