There are two methods for measuring changes in penile rigidity and circumference during nocturnal erection: snap gauge and strain gauge.
This setup is frequently used in strain gauge and resistance thermometer measurements, as it is usually faster to read a voltage level off a meter than to adjust a resistance to zero the voltage.
With the strain gauge and a filter, amplifier, and analog/digital converter, the strain on an object can be measured.
