SHINKAWA变送器WK/WKN系列介绍

WK/WKN系列是在涡流传感器上增加了振动转换功能或推力转换功能的产品。2线电流环驱动,可直接传输4~20mA信号,节省振动监测系统成本。

 

特征

无需振动监测器或振动转换器(4 至 20mA 输出)

电流输出,可进行远距离布线

直接连接到控制设备等的能力。

适用于通用压缩机等小型旋转机械的振动监测

本质安全防爆结构(非易燃)

 

The WK / WKN series is a product that adds a vibration conversion function or thrust conversion function to an eddy current transducer. Driving by a 2-wire current loop can directly transmit 4 to 20 mA signals so that the cost of the vibration monitoring system is saved.

 

Features

No need for vibration monitor or vibration converter (4 to 20mA output)

Long-distance wiring capable because of the current output

Direct connection capability to control devices and so on.

Ideal for vibration monitoring of small rotating machines such as general-purpose compressors

Intrinsically safe explosion-proof structure (Non-incendive)
