You should contact Limestone to see if they have a technical datasheet for the device.
Aren’t those controversial? It used to be thought that orientation and desire were mutable, but that is no longer thought to be the case. Adversion techniques (think A Clockwork Orange) have fallen out of practice. I imagine there could be some ‘creative’ uses for a penile sphygmomanometer though.
A previous post on one of the forums here indicates that the resistance will be in the order of six Ohms, so you will want a single-supply op-amp which works with inputs down to the negative rail. Calibration is somewhat arbitrary, so precision and drift are not too much of a worry; it should not be too much trouble to set it up with the op-amp, grounding the strain gauge and feeding it via a 100 Ohm resistor to Vcc - the same Vcc which is the reference for the Arduino.
Liberos:
I have a Seeed mounted on an Arduino UNO for other measures,
Sorry, that does not mean anything.
Controversial? He may simply be using it for NPT studies. Note the price tag on the female version though!
If you Google ( carefully) , these things were used in the US army to check for “ sexual orientation “ of new recruits in the 1950’s and were called “ Peter meters”.
I did some experiments with these but always broke the strain gauge

You were probably using one that was too small. The Limestone units go up to 110 mm diameter.
