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)
