CPL350 Capacitive Displacement Sensor

August 01, 2015

The new CPL350 is a small, precision capacitive displacement sensor from Lion Precision. The single-channel sensor brings top-shelf performance into tiny spaces at more affordable prices. Ideal for embedded and OEM applications.

Designing machines that require embedded, high-precision position sensing can be a frustration for engineers and designers. Non-contact sensing with resolutions in the nanometer range often means a large rack-mount or modular bench top style design. Machinery may not have the space available for such a system. Additionally, the sensor electronics may have front panel adjustments which are not easily accessible once installed in a machine. These larger precision systems can also be challenging to the design's cost controls.

Lion Precision's new CPL350 now provides a better option. The single-channel system provides measurement performance approaching that of their top-of-the-line Elite Series modular systems. Resolutions as high as 0.0007 percent at 100 Hz or 0.004 percent at 15 kHz. It does all this in 2x2x4 inch package (50x50x200mm). A BNC single-ended output is provided, or for maximum resolution with longer cable runs, a differential output is also available.

With no user adjustments or displays, the CPL350 electronics can be installed in out-of-the-way places. Sensors typically ship with 15 kHz bandwidth. Users can access an internal dip-switch to set the bandwidth to 15 kHz, 10 kHz, 1 kHz, 100 Hz. The bandwidth selection allows users to opt for higher resolutions or higher speeds.

The sensor is easier on designers' budgets at approximately 35 percent lower cost than a single-channel Elite Series system.
