详细信息
2700系列电流压力传感器结合了经济的启动成本，低空气消耗，可靠的性能。该装置将可变电流信号转换成比例气动输出。它的输入和输出端口都在前面和后面，NEMA 4X外壳使得该设备可以安装在室内或室外，但是，该设备并不是抗振动的。它是FM和CSA批准的本质安全操作。2700是专为远程或面板安装。一个整体体积助推器提供高流量，增加控制速度的关键应用。其他特点包括外部零点和跨距调整，便于现场校准。
该系列2800电流压力传感器采用闭环压力反馈系统，紧密控制输出和补偿振动、安装角度、温度和供应压力的变化。这些特性使这种装置非常适合安装在阀门上。控制机制是一个压电陶瓷驱动器封装在一个保护性的皮肤，它提供了一个恒定的防御湿度和污染物。这些特性使该单元非常适合用于要求高的应用程序。2800还来在一个NEMA 4X封闭和现场可逆。它是FM和CSA批准的本质安全，以及。为了便于安装，这种型号的输入和输出端口都在前面和后面，可以很容易地面板安装
