It would be desirable to measure the pressure of a brake circuit for diagnosing and telemetry purposes.
The dynamometer in the shop already has a pressure transducer on it, however it is only rated for 0-300 psi, which is not nearly enough for our purposes. It is believed that the pressure developed within the brake circuit is at least around 1500 psi.
A pressure transducer like the one on the dynamometer for our pressure range is too expensive (>$600), so we will attempt to use readily available automotive aftermarket parts.
Here is a possible candidate:

Pinout for the sensor from a Nissan maintenance manual:
It is believed that these sensors are powered by 5V and return a variable voltage through the SIG pin, relating to the pressure in the brake circuit.
The largest hurdle to get these sensors working is getting the correct fittings for them to work with out brake system.
