2
O)
• Connector tube diameter: 4 mm (4-5 mm adapter included)
• Measurement uncertainty: +/- 0.5 Pa +/- 4% of reading
• Resolution: 0.25 Pa
• Offset shift due to temperature variation: none (less than resolution)
• Span shift due to temperature variation: < 0.5% of reading per 10°C
• Offset stability: < 0.1 Pa/year
• Response time: 4.6 ms typical
• Media compatibility: Air, N
2
• Limited media compatibility: O

• Wet materials: PBT (polybutylene terephthalate), glass (silicon nitride,
silicon oxide), silicon, gold, FR4, silicon as static sealing, epoxy, copper
alloy, lead-free solder, fully RoHS compliant.
• Allowable overpressure: 1 bar (100 kPa, 400 inches H
2
O)
• Allowable tubing length is 1 m (max)
• Rated burst pressure: > 5 bars
• Air flow through the sensor creates a dependency on tube length.
Error is less than 1% with a tube length up to 1 m (with 3/16 inch
inside diameter)
