I think you'd have to build one. Get a pressure sensor and run it in parallel with a pullup resistor tied to 5v if your resistance is high enough. You can measure the voltage with a battery voltage sensor.

Im thinking it is above 10 bar so it will need to be welding supply stuff. Haven't seen an high pressure electronics sensor for less than couple hundred$
