Displacement Measurement - Non Contact

Cylindrical Sensor Probe Series – HPC Series

(Capacitec)

Applications:

Displacement and Position Measurement

The cylindrical probes are the most popular version of the non-contact series. Its case is an additional component added to the sensor and guard elements to avoid being earth grounded. A set screw or split clamp housing is normally designed to hold it in place for easy adjustments.

The guard element is driven with an electronic voltage 2 to 20 Volts P - P maximum and must not be grounded.

-D dip coatings also prevent the driver, sensor and guard elements from being accidentally earth grounded or shorted. (not available on "V" and "S" series probes)

Range values tested with 5 ft. (1.524 meters) of Capacitec L2 cable.

Range and signal to noise ratio will be degraded by longer cable lengths.

A 20 point archived calibration record of voltage output versus nominal displacement is provided standard with every probe.

Sensor must be calibrated with final length of cable for stated results. All components are electronically isolated from each other by greater

than 20 megohms of leakage resistance (at room temperature) for best operation with the instrumentation.
