Vernier Gas Pressure Sensor

|
The Gas Pressure Sensor has enough resolution and range to work for all subject areas. Chemistry teachers will find that it has enough range for Boyle's law experiments (0 to 2.1 atm), yet provides greatly improved resolution for vapor pressure or pressure-temperature experiments (0.40 mm Hg with LabPro). The connection valve is now directly on the sensor box, significantly reducing dead air space. For biology teachers, the package includes airtight tubing clamps for transpiration experiments, as well as special fittings for respiration experiments in small containers.
Specifications
- Pressure Range: 0 to 210 kPa (0 to 2.1 atm or 0 to 1600 mmHg)
- Maximum Pressure that the sensor can tolerate without permanent damage: 4 atm
- Resolution, 12-bit (LabPro, Go! Link, ULI II, Serial Box): 0.05 kPa (0.0005 atm or 0.40 mmHg)
- Resolution, 10-bit (CBL, CBL 2, original ULI): 0.002 atm or 1.6 mmHg
- Sensing Element: SenSym SDX30A4
- Combined Linearity and Hystersis: typical +/-0.2% at full scale
- Response Time: 100 microseconds
