We provide optimized sensing solutions based on non-contact type Capacitance & Eddy Current sensors for measurements like position, displacement, thickness with high speed & high resolution.
Capacitive Sensors
Features:
Measurement Ranges: 10 µm to 10 mm
Resolution: Low as 0.4 nm
Bandwidth: up to 15 kHz
Linearity: 0.2%
Conductive and nonconductive targets
Advantages:
Higher resolutions including subnanometer resolutions
Not sensitive to material changes: Capacitive sensors respond equally to all conductors
Less expensive and much smaller than laser interferometers.
Applications:
Position Measurement/Sensing, Displacement Measurement
Automation requiring precise location
Semiconductor processing
Final assembly of precision equipment such as disk drives
Precision stage positioning
Dynamic Motion
Precision machine tool spindles
Disk drive spindles
High-speed drill spindles
Ultrasonic welders
