MS系列微差压变送器
测量风压或风速
MS系列 Magnesense®微差压变送器用途广泛，可用于监测微压/微差压/真空，和监测风速/风量。它的功能包括：可现场选择公制/英制工程单位，可现场加装LCD数显，可调整输出信号的阻尼系数，当和皮托管或其它差压风速传感器配合测量风速风量时，可选择开方输出。
磁感应技术使得Magnesense®微差压变送器性能优异，稳定可靠。可用于所有的微差压，风速风量测量的应用场合。

• 现场升级为LCD数显无需仓储两台不同的变送器，只需移除前盖，将LCD组件插入，就现场组装了一台带数显的变送器，可轻松满足用户的需求。
• 现场可选量程不管是英制或公制。无需太多的仓储量，你总有能满足量程要求的变送器。
• 数字按键校准零点和量程取代传统的电位器校准的方式，大大节约了校准时间，降低了维护成本。
• 可调数字阻尼用于平滑频繁波动的压力，常用于气流监控应用场合。
• 可现场改为风速型用于风机等应用场合。可采用平方根输出直接显示fpm或m/s风速。无需用智能可编程显示仪或PLC来换算差压成风速。不仅节约硬件成本，而且减少安装时间。
