WDA 是一款大功率宽程电磁感应接近传感器，不受物粉尘或料堆积影响，用于监控黑色金属目标，探测距离最远可达100mm。WDA 传感器可以用通过检测金属畚斗或塑料畚斗上的金属螺栓来监测斗提机的速度或跑偏。WDA 的另一个特别用途是用来检测牵引式链式输送机链条松脱或断裂和螺旋输送机的速度监测。WDA 提供连个输出信号：一个是脉冲信号表示检测到的每一个畚斗，另一个是检测到运动的畚斗是发出的连续信号。

Watchdog™ 超级精英 (WDC4)
Watchdog 超级精英系列(WDC4) 安装设置都很简便。WDC4 系统处理来自皮带跑偏传感器、皮带速度/打滑传感器、连续轴温传感器、皮带轮跑偏传感器和物料堵塞他侧传感器的信号输入， 当任意一个传感器检测到达到或超出报警设定值的状况时，系统发出警报声并提供斗提机或输送机停机信号和喂料机停机信号。
WDC4 主屏幕显示控制器的主要系统状态。可以直接在系统的 LCD 屏幕上完成系统设置或者在电脑上完成设置后用 SD 卡转移到控制器，控制器的设定受密码保护。Watchdog 超级精英系列可以通过 Modbus TCP/IP 通讯协议直接与 PLC 连接，也可以支持 HazardMon.com® 灾害监控云平台，这是一个基于云计算的灾害综合监控平台，可向用户提供实时系统状态信息、图表和历史数据查询服务，任何能上网的网络终端（手机，平板电脑，台式机）都可以直接查看。
FAQ's
The WDA sensor will not calibrate, what is the issue?
Make sure that the orange wire is connected correctly, this powers the potentiometer (calibration screw).
Why will the LED on the back of the sensor not turn on?
Check to see that there are no objects stuck to the face of the sensor (washer, bolts, etc.). Due to the magnetic pull on the face of the sensor, objects can stick and interfere with the sensor.
What if the best sensing depth of the WDA sensor?
The WDA sensor can detect ferrous targets from 1 to 3 inches away. Keep in mind the distance of other objects within the sensing area. For example, a belt splice on a bucket elevator may be longer than the intended target and can interfere or hit the WDA sensor.
