616KD-B-50/51/52/53/54/55/56/57/58 Dwyer德威尔 差压变送器

带***键校准技术的616KD差压变送器结构简单，便于安装和专业维护。

这个***键校准的差压变送器是性价比高，小巧,价格低的变送器。它不仅消除了象其

它变送器***样的繁琐的调整，而且无需校准量程。只需按***按键就能将零点和量程

校准。无需使用参考压力源和其它校准设备，无需卸下再送到校验室去校准。所有

需要做的事情就是在差压平衡为零的时候按下按键，比起传统的变送器要每年拆卸

变送器送去校准量程来说，它能在产品服务期内节约大量时间。和外壳***起模压的

安装孔使得安装非常简单。

616KD还能够安装在35mmDIN导轨上，带侧面和背部的导轨卡。在外壳的上部，它

带有容易接线的接线排。可选择带有接线排保护盖。

***键校准技术***族的差压变送器***理想用于楼宇自动化应用场合：空气处理机，风

管，变风量和过滤监测。根据选择的型号不同，可以选择的量程从1英寸水柱到20英

寸水柱。
