Capacitance Free Length Gage
Capacitance Free Length Gage

The Capacitance Free Length Driver is a self contained system for driving the non-contact probe. The driver electronics produce an output voltage, which is proportional to the length of the spring at the probe. Longer springs (closer to the probe) produce more positive output voltages.

The output voltage offset must be adjusted to near zero for a nominal length spring. Probe Zero adjustments can be made by a Digital to Analog Converter output voltage from the users data acquisition system or by a ten-turn potentiometer that can be purchased with the system.

The probe driver is mounted with two screws (M3-0.5). Do not loosen or remove the probe connector nut. See Figure 3 for panel cutout specifications. The maximum depth of the threaded mounting holes is 9.5mm (3/8 inch).
