- Pressure sensor for Mindstorms NXT.
- 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 NXT Mindstorms system capable of measuring up to 250 kPa (30 psi) and 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:
The dPressure sensor comes in two versions:
- The dPressure 250: Vacuum to 250 kPa (30 PSI)
- The dPressure 500: Vacuum to 500 kPa (70 PSI)
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.
