差压传感器 SDP800系列
SDP800 – 成熟与提高
SDP800系列是用于苛刻且成本敏感的HVAC应用（如VAV控制器、燃烧器、热回收系统和过滤器监控）中的精确气流测量的解决方案。
SDP800是基于新一代 CMOSens® 传感器芯片，具有SDP600系列成功的特性。该差压传感器是超过15年测量数以百万计的患者、汽车发动机和HAVC系统的流量经验的结晶。由于其成熟的外形尺寸，SDP800系列集成方便传感器芯片提供扩展的功能、智能平均功能和多种测量模式。像所有Sensirion差压传感器一样，SDP800系列精度出色，长期稳定，无零点漂移。
多种配置
- 歧管或管连接
- 125 Pa 或 500 Pa
- 数字 (I2C) 或模拟输出
数字版功能多样，有高达2kHz的灵活测量速度、多种测量模式（触发/连续）和只能平均功能。模拟版可通过单独引脚配置为线性或平方根输出。SDP80x适用于通过O形环密封，直接连接歧管，而SDP81x适用于管连接。
SDP800系列基于Sensirion的CMOSens® 技术，将传感器、信号处理和数字标定集成在一个芯片上。它通过采用流通原理的热式传感器元件来测量差压。得益于此，在低差压灵敏度、零点漂移和滞后、位置敏感、抗冲击和温度变化等方面，Sensirion的CMOSens® 差压传感器优于传统压阻模式传感器。
