Pressure sensor for LEGO MINDSTORMS NXT. The dPressure 500: Vacuum to 500 kPa (70 PSI) Датчик давления для LEGO Mindstorms NXT и EV3 Pressure sensor 500 kPa Арт.: 128-74-96 Plugs directly into your NXT sensor ports. Adapter for LEGO Pneumatic kits included. Widest pressure range: 250 kPa (30 PSI) or 500 kPa (70 PSI). Easily incorporated into datalogging experiments in chemistry, physics, and engineering. Detailed Description The dPressure is a pressure sensor for the LEGO® MINDSTORMS NXT system capable of measuring up 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 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. Technical Specifications: Both sensors measure differential pressure and have 1/8" ports. These analog sensors can measure down to 0.25 kPa (0.04 PSI) in pressure change and has a response time of 1 ms.
