GETTING HELP
The CPL350 is compliant with the following CE standards:
Safety: EN 61010-1:2010
EMC: IEC 61326-1:2013, IEC 61326-2-3:2013
To maintain compliance with these standards, the following operating conditions
must be maintained:
• All I/O connecting cables must be shielded and less than three meters in length
• Use the included CE approved power supply. If an alternative power supply is used, it must
have equivalent CE certication and provide safety isolation from the mains according to
IEC60950 or 61010.
• Sensors must not be attached to parts operating at hazardous voltages in excess of 33VRMS
or 70VDC
Use of the equipment in any other manner may impair its safety and EMI protections.
The CPL350 Capacitive Displacement Sensor provides one channel of noncontact displacement
measurement for precision position and displacement applications. This manual will provide you
with all the information you require to get the greatest benet from your system.
Engineers, technicians, and maintenance personnel will nd the CPL350 invaluable for high-
precision measurements of mechanical displacement where contact with the target is not
possible nor advisable. Targets such as high-speed rotating spindles, or parts that could be
damaged or deected by contacting probes can be measured with condence and accuracy.
Your system includes this manual, the CPL350 Capacitive Sensor electronics, power supply, one
probe, and a NIST traceable calibration sheet.
Your system was calibrated with a precision calibrator designed by Lion Precision. The system is
calibrated with nanometer precision. All of our calibrations are traceable to NIST.
Lion Precision recommends that you have your system recalibrated at the factory once a year to
ensure maximum accuracy.
In this manual you will nd information for connecting and using your CPL350. Once you
become familiar with the system, you will only need to refer occasionally to this manual for
specications or to verify connection information.
Lion Precision wants to help you get the most from your system. If there is anything we can do,

TECHNICAL LIBRARY
CONNECTING TO THE CPL350
Our website includes a Technical Library lled with useful information on making the most
precise measurements possible, as well as product information and manuals:
www.lionprecision.com, click the Technical Library menu item.
Probe Connections
To Connect the Probes
1. Insert the probe cable connector into the “Probe” connector on the CPL350.
2. Rotate until the red dots on the connectors align.
3. Push the connector in until it clicks.
To Disconnect the Probes
1. Pull on the knurled barrel of the probe connector which will release the latching mechanism.
The probe cannot be disconnected by pulling on the cable.
Analog Output BNC Connector
Single-Ended ±10 V
Analog output is ±10 V. The output voltage becomes more positive as the probe gets closer to
the target. The scaling of the output (i.e. V/mm) is dependent on the probe and calibration
specied when ordered. The complete calibration information is available on the NIST traceable
calibration sheet provided with the sensor.

Power Supply Requirements
The power supply provided with your CPL350 provides the required ±15VDC input power. If
using your own power supply, be aware that high-frequency noise from a switching-type power
supply may appear in the output. For high resolution results, be sure to provide clean power.
Dierential Outputs
The Non-Inverted and Inverted outputs are used together as a dierential output. Dierential
outputs help eliminate electrical noise induced into the connecting wires by noise sources such
as computers, power transformers etc.
The Non-Inverted output voltage becomes more positive (relative to ground) as the probe nears
the target. The Inverted output voltage becomes more negative (relative to ground) as the
probe nears the target. The Non-Inverted and Inverted outputs are each ±5 VDC relative to
ground; the dierential output is therefore ±10 VDC.
Do NOT connect the outputs to ground or the unit will be damaged.
Dierential Outputs as Single-Ended
The Non-Inverted or Inverted outputs can be used as a ground referenced single ended output,
but the sensitivity will be half of that indicated on the calibration sheet. For instance, a
dierential output calibrated for 1 V/mm will produce 0.5 V/mm when used as a single-ended
output.
Signal Ground Connection
A ground connection screw is provided for an optional ground connection to data acquisition
devices. Connecting the CPL350 ground and data acquisition ground may improve performance.
Consult your data acquisition manual for more details.

CHANGING BANDWIDTH
Higher bandwidths allow you to accurately measure faster moving targets.
Lower bandwidth reduces the noise on the output and creates higher resolution.
The CPL350 is set to 15 kHz unless specied otherwise in the order and on the calibration sheet
received with the system.
Two switches inside the enclosure set the bandwidth. To change them:
• Remove the 4 screws that attach the front panel to the cover.
• Bandwidth is controlled by positions 3 and 4 of DIP-switch S1.
DO NOT CHANGE ANY OTHER SWITCHES
Set the desired bandwidth according to the this table:
