WDB810V3AI, WDB819V3AI, WDB811V3AI, WDB812V3AI, WDB813V3AI, WDB814V3AI, WDB815V3AI, WDB20V3CAI, WDB29V3CAI, WDB21V3CAI, WDB22V3CAI, WDB23V3CAI, WDB24V3CAI, WDB25V3CAI, WDB10V3AI, WDB19V3AI, WDB11V3AI, WDB12V3AI, WDB13V3AI, WDB14V3AI, WDB15V3AI

The WDB series bearing sensors are designed to screw directly into a bearing housing. Each sensor is fitted with a grease zerk to allow lubrication of the bearing without the need for removal of the sensor.

The WDB8 series have a 1/4” BSPT thread. The WDB2 series have a 1/8” NPT thread. Three versions are available; an NTC thermistor or Pt100 RTD type for continuous temperature monitoring, and a PTC thermistor model with the following trip points (specify when ordering): 60°C, 70°C, 80°C, 90°C for step (Cold/Hot) temperature monitoring.

The sensor is supplied with a three meter attached cable and can be connected to a hazard monitoring system, such as 4B’s T500 Hotbus Elite, Watchdog Super Elite, or T400 Elite or to a PLC. The connections are not polarity sensitive therefore special connection requirements are eliminated, and the cable can be extended in the field.

    Watchdog™ Super Elite (WDC4)

    Watchdog Super Elite hazard monitor (WDC4)
    Watchdog™ Super Elite (WDC4)

    The Watchdog Super Elite (WDC4) is easy to install and simple to set-up. The system processes signals from sensors for belt misalignment, belt speed & slip, continuous bearing temperature, pulley misalignment and plug conditions for bucket elevators or belt conveyors.  When an alarm is detected it will sound an alarm and provide shutdown control of the elevator/conveyor and feeding system.
     
    A 3.5” LCD screen displays the entire system status at a glance.  Password protected controller settings can be set up either directly on the LCD screen, or by a PC application and transferred to the WDC4 via an SD card.
    The Watchdog Super Elite can be connected directly to a PLC using the Modbus TCP/IP protocol, or integrated into HazardMon.com®.  This secure cloud based solution provides live system status, graphs and historical data that is viewable on any web-enabled device (smart phone, tablet, desktop PC).

    IE-Node

    IE-Node
    IE-Node

    The Industrial Ethernet Node (IE-NODE) is a remote monitoring interface designed to provide sensor data to PLC’s or other automation and control systems.

    Both units can be expanded to 16 sensor inputs with the installation of optional expansion boards.

    The IE-NODE operates by reading its sensor inputs and sending processed data when requested by another system (e.g. PLC). The units are equipped with an RJ45 Ethernet socket and supports PROFINET, EtherNet/IP and Modbus TCP/IP protocols for easy integration with Siemens, Allen-Bradley Rockwell, Modicon and other PLC’s or automation devices.

    The IE-NODE’s network configurator software provides a visual view of all devices on the network. It allows for easy identification of each unit on the network and allows for network settings to be changed as needed.
