CAD Files | Capacitive Sensors: Standard Probes

Probe Sensing Area

The probe sensing area determines the probe’s measurement range.

Larger Sensing Area = Larger Range




Sensing areas are indicated by diameter in mm. They are combined with the Probe Body Model to form a probe model number such as C8-2.0.

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

Standard Probe Operating Environment

4°C-50°C; 40°F-120°F

Probes can be used at colder temperatures, including cryogenic temperatures, when condensation (frost) is prevented and the system is specially calibrated for the target temperature range.

Standard Probes can be ordered as vacuum compatible.

Custom Probes

A large percentage of our probes are customized for unique applications. Our custom probes page has some examples.

Standard Probe Body Styles

Standard probe cable length is two meters.
