I want to use a sensor interfaced to a Arduino board to measure pressure in range of 0 to 200 bar in hydraulic brake line hoses.
We would suggest the IMP industrial pressure sensor which has the option for a 0.5-4.5 volt dc output which will operate from a 5 volt supply voltage, both of which are provided by the Arduino, since it has a 0-5 volt analog input and a fixed 5 volt power output:
IMP Pressure Sensor
- Part No: IMP-G2003-9A4-BAE-00-000
- Pressure Range: 0 to 200
- Units: bar
- Range Type: Positive Gauge (atm to +P)
- Output Signal: 0.5 – 4.5V, 3-wire ratiometric (9)
- Non-Linearity and Hysteresis: 0.25% FS (standard) (A)
- Thermal Zero Shift: 0.04% FS per °C (standard) (4)
- Electrical Connection: Large DIN plug (standard) (B)
- Process Connection: G1/4 male DIN 3852 (A)
- Media Exposed Seals: EPDM (E)
- Special Requirements: Standard (000)
