The dPressure is a pressure sensor for the Lego Mindstorm NXT and EV3 systems 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.
- Pressure sensor for Lego Mindstorm EV3 and NXT.
- Plugs directly into your NXT sensor ports.
- Adapter for Lego Pneumatic kits included.
- Widest pressure range: 500 kPa (70 PSI).
- Easily incorporated into datalogging experiments in chemistry, physics, and engineering.
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.
