1. Measuring Range, Maximum measurement distance of the sensor probe.
2. Linearity, an industry-standard parameter, reflects the absolute accuracy of sensor measurements under factory calibration conditions.
3. Sensitivity, an industry-standard parameter, refers to the ratio of the sensor system’s output change to the input change – specifically, the magnitude of the output voltage corresponding to a unit displacement.
4. Resolution, an industry-standard parameter, refers to the minimum displacement increment measurable under a specific bandwidth, given as the RMS noise value.
5. Dynamic (resolution), refers to the resolution at a 10 kHz bandwidth.
6. Static (resolution), refers to the resolution at a 20 Hz bandwidth.
7. FSO, an abbreviation for Full-Scale Output.

Features · High-speed Real-time Communication

20 μs/point Real-time Communication for
Ultra-precision Motion Closed-loop Control

In a motion system achieving speed up to 200 mm/s with nanometer-level precision, the C1-FLT sensor paired with the Faraday.03 monitor provides real-time position information for closed-loop control.

The Faraday.03 performs position updates every 20 ms, offering critical support for PID dynamic control.

The closed-loop system completes five motion phases – startup, acceleration, uniform motion, deceleration, and stop – in 5.3 ms, achieving a smooth 1-nm step without overshoot.
