WDB 系列轴承温度传感器直接用拧紧轴承座上原有的黄油嘴，传感器上带有黄油嘴，可以对轴承进行润滑而不需要拆下传感器。
WDB8 系列的连接螺纹为1/4” BSPT, WDB2 系列为1/8” NTP 螺纹。感温元件有三个类型，NTC 负温度系数性或 PT100 RTD 型探头用于检测连续温度，而 PTC 型则可以预先设定跳闸点温度（订货时明确）：60°C、70°C、 80°C 和 90°C，用于阶跃响应温度控制。
传感器电缆标准长度为3米，可以直接联结 PLC，也可以接入4B 的 T500 精英型安全监控网络控制器 、 WDC4 综合安全监控单机控制器或 T400 精英型温度专用控制器，以获得更精准的监控效果。导线没有极性，可以任意连接而且长度可以自由加长。
