Compact Driver Multi-Channel Capacitive Sensor Probes and Ranges

Probe Sensing Area | Calibration Types | Ranges

Probe Sensing Area

The sensing area determines the probe's measurement range.

Larger Sensing Area = Larger Range

Sensing areas are indicated by their diameter in mm and are combined with the probe body style to form a probe model number such as C8-2.0 (C8 body style and 2.0 mm diameter sensing area) or C18-13 (C18 body style and 13 mm sensing area).

Target area diameter must be 130% of the sensing area diameter or custom calibration will be required.

Probes can be ordered as vacuum compatible.

Custom probes are available.

Compact Driver Calibration Types

Two different calibration types are available enabling you to find the optimal pairing of range and resolution.

Compact Driver Ranges/Resolutions - Sorted by Sensing Area Size (Smallest to Largest)

Custom calibrations can acheive exceptional resolution performance

Larger Sensing Area = Larger Range

* Resolution values are RMS. Peak-to-peak values are typically ten times greater than the RMS values.
