Water pressure in a tube: MPRLS Ported Pressure Sensor?

by walterkou on Fri Aug 09, 2019 1:24 pm

Hi all,

I want to measure the water (or saline) pressure in a chamber that is used for research. The chamber has a hole (with on/off switch) that is ready to connect with one end of plastic tubing. So a plan is to connect a pressure sensor in the other end of tubing.

I ordered ( and still wait for) Adafruit MPRLS Ported Pressure Sensor Breakout - 0 to 25 PSI, as it seems to like tubing. However, I am worried whether the pressure sensor in the port can be wet by water or saline?

Do you have other recommendation on pressure sensor? (Water resistant pressure sensor that is able to connect tube).

Thanks,
Walter

The datasheet says the MPRLS sensor is rated for indefinite exposure to moisture, and lists applications that include CPAP water tanks, dishwashers, and washing machines.

You should be okay.
