CPA100 Capacitive Displacement system

The Lion Precision CPA100 Capacitive Displacement Sensor provides repeatable noncontact measurement of position changes of conductive targets; the CPA100 can also detect nonconductive targets in many applications.

The CPA100 provides a nonlinear analog voltage proportional to changes in the target position and a digital switched (setpoint) output.

Multiple Sensors

When multiple sensors are used with the same target, the sensors must be synchronized for best performance. A synchronization kit includes a cable and “T” connector for each channel. If sensors are not synchronized, interference will increase output noise, especially at lower frequencies.

Maximizing Performance - Ungrounded Targets
Ungrounded targets have the potential to inject noise into the sensor. If the output is unusually noisy, be sure the target is grounded. On moving/rotating targets this can be accomplished with a small metal brush or thin piece of metal which is connected to ground.
