D-510 PISeca Capacitive Sensors

Single-Electrode Sensors with Excellent Position Resolution

Noncontact distance measuring
Absolute position sensing
Vibration measuring
Subnanometer resolution
Flexible measuring range
Easy integration

In conjunction with the electronics for signal processing, a resolution can be reached in the subnanometer range for quasistatic applications. The bandwidth can be increased up to 10 kHz for high dynamics application, where a resolution in the 1 nm range can still be reached. The linearity error is under 0.1%.

All PISeca sensor heads are equipped with a LEMO connector for easy mounting and replacement. The uniform shaft thickness ensures compatibility and flexibility. The cable for connecting to the evaluation electronics is available in several variants and must therefore be ordered separately.

In addition to the standard sensors listed here, PI offers a series if application-specific custom versions where for example, the measuring range, geometry or material are adapted to customer requirements. Customized electronics are also available.

The two-electrode sensors in the D-100 series are available for the highest demands on linearity and resolution.
