S3000CA 是以真空为基准的绝压变送器，量程可从 0-2.5kPa 至 250kPa、0-30kPa 至 3MPa 选择。由于基准是真空而非大气，读数不随大气压变化漂移，适合真空蒸馏、真空包装与蒸发器绝压控制等场合。
接液膜片可选 316L 不锈钢、哈氏合金 C、镀金 316L 或 FEP 涂层 316L，既能适应温和的蒸汽与气体，也能应对强腐蚀性介质。可测量液体、气体与蒸汽，按 ISO 9001 质量管理体系制造，CE/RoHS/FDA 合规视型号而定。
绝压与表压有什么区别？
绝压以真空为基准，包含大气压力，不随天气变化漂移；表压以当地大气为基准，会随气压波动而变化。
如何选择膜片材质？
水、蒸汽与温和化学品选 316L；强酸选哈氏合金 C；含氢或高纯工艺选镀金 316L；强腐蚀介质选 FEP 涂层 316L。
S3000CA 能测气体吗？
可以。它支持液体、气体与蒸汽；真空基准设计尤其适合气体工艺，因为大气压变化不会导致读数偏移。
有哪些量程可选？
提供两组量程：0-2.5kPa 至 250kPa、0-30kPa 至 3MPa，可覆盖绝大多数真空及中低压工况。
