809系列压力变送器/ 传感器
OEM工业用压力变送器
特性...
- 传感范围从真空到10,000 psi
- 耐用不锈钢& Valox®外壳
- 应用于高振动&高冲击场合
概况/设计原理:
809系列压力变送器专为工业应用高性价比要求而特别设计,在典型工业场合可靠性强。809系列压力变送器运行维护成本低,稳压直流供电,适用于大多数气体和液体的温度范围。专门应对恶劣环境的设计,使得该类产品适于高冲击、高振荡场合应用。不锈钢及Valox®外壳轻便小巧,易于合其他整体系统集合。809系列产品标准特性使其在满足极端环境条件苛刻要求的前提下,仍处在OEM厂商所青睐的经济价位下.
运行原理:
809系列传感器采用成熟的中心安装电极构造,集合耐用型17-4PH不锈钢压力传感元件共同构成变容器。压力(或真空度)增大或减小时,电容随之变化。独立高级输出集成电路系统将电容变化转换为完全可调的线性电压或电流输出信号.
