Multi-channel capacitive displacement sensor system from Lion
Lion Precision's new CPL230 precision capacitive displacement sensor system features up to six sensors in a small space. Its performance approaches that of top-of-the-line systems but costs 25 per cent less and is suitable for embedded OEM applications.
Engineers and designers who develop equipment requiring precise noncontact position sensing have struggled with getting the performance they need into the small space and budget they have available. Multi-channel precision capacitive displacement sensor systems are often large modular designs offering user adjustments and indicators. These systems have many uses, but for OEM applications, the electronics may be buried in a cabinet where users cannot see the displays or make adjustments. And OEM applications require cost control.
Lion Precision's new CPL230 changes all of that. The new sensor system can support up to six channels of capacitive sensing with performance approaching that of their top-of-the-line Elite Series modular systems. Resolutions are as high as 0.0007 per cent at 100Hz or 0.004 per cent at 15kHz. It does all this in 4×2×8 inch package (100×50×200mm). A differential output is provided for maximum performance when output connections must traverse longer distances through machines.
The CPL230 has color-coded channels and probes for easy installation into machines. With no user adjustments or displays, the electronics can be installed in out-of-the-way places. Systems typically ship with 15kHz bandwidth. Users can access an internal dip-switch to set the bandwidth to 15kHz, 10kHz, 1kHz, 100Hz. The bandwidth selection allows users to opt for higher resolutions or higher speeds.
This system is easier on designer's budgets at approximately 25 per cent lower cost than the Elite Series systems. The CPL230 replaces Lion Precision's Compact Driver. The Compact Driver was also designed for embedded use and lower cost but could not provide the higher measurement performance required by some designs.
CPL230 specifications:
- Measurement ranges: 10um to 12.5mm (0.0004 to 0.5 inches)
- Maximum bandwidth: 15kHz
