The dPressure is a pressure sensor for the LEGO® MINDSTORMS® NXT system capable of measuring up to 500 kPa (70 psi) of pressure and gauge vacuum. The sensor comes with an adapter for LEGO Pneumatic lines.
The sensor is easy to use: it plugs directly into the EV3 or NXT and users can be up and reading pressures in seconds.
These pressure sensors can easily be incorporated into chemistry, engineering, and environmental experiments with NXT-G and Labview.
The dPressure500 measures Vacuum to 500 kPa (70 PSI) The sensor measures differential pressure and have 1/8" ports.
The analog sensor can measure down to 0.25 kPa (0.04 PSI) in pressure change and has a response time of 1 ms.
