Touchswitch™
Belt & Pulley Misalignment Sensor
TS2V34AI, TS2V34AI, TS2V3CAI, TS2V4CAI, TS2V34AI-FG, TS2V34AI-HT

The Touchswitch is an electro-mechanical limit switch with no moving parts, which detects tracking and misalignment problems on bucket elevators and conveyors. When a belt misaligns or a pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley and activates a voltage free solid state relay output. This output signal is used to immediately alarm and ultimately shutdown the machine.

The face of the sensor is made from hardened and annealed stainless steel, not soft brass or aluminium, so wear life is longer when a belt contacts it. The Touchswitch is not affected by dust or material build up and will still work when completely covered by material. An external test wheel allows for quick and simple sensor/system testing. The sensors are usually installed in pairs on opposite sides of the machine. The sensors can be connected directly to a PLC input, or for greater safety, to a central independent monitoring system, such as Watchdog Super Elite, IE-Node or the T500 Hotbus system.

    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.

    B400 Elite Beltswitch

    B400 Elite Beltswitch
    B400 Elite Beltswitch

    The B400 Elite Beltswitch belt misalignment monitor uses 4B Touchswitch sensors to monitor belt alignment in bucket elevators and conveyors. Each control unit incorporates two independent monitoring circuits for early detection of belt misalignment on one or two bucket elevators / conveyors. The 4B Touchswitch is an electro-mechanical limit switch with no moving parts. When a belt misaligns or a pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley and activates a voltage free relay contact. Status LEDs on the control unit indicate the alignment condition of the belt, while internal relay contacts provide alarm and automatic shutdown of the elevator when hazardous misalignment conditions are detected.

    X400 Elite Alarmswitch

    The X400 Elite is a microprocessor controlled low cost alarm indicator panel for use with level indicators, hazard controls and limit switch sensors. The X400 accepts signals from different sources in up to 8 zones, and is able to cause alarm and shutdown of the machine when an alarm condition has been detected. Alarm and status LEDs on the lid of the X400 provide quick location of alarm conditions. Alarm muting can be performed at the panel or by an optional remote push button to silence external alarms. If the system is muted, it will automatically reactivate when a new alarm is triggered. Testing can also be activated at the panel, providing full system verification.

    PRODUCT DETAILS

    Is the Touchswitch™ a rub block?

    No, the Touchswitch is a pressure sensitive contact switch.  When the belt misaligns and contacts (touches) the sensor with enough force, an alarm is triggered.

    Rub blocks are designed to detect the heat generated by friction when the belt rubs against the brass block. In dust hazardous environments, heat is what you are trying to avoid. Also, belts can misalign and rub against the brass for a short period of time, but not long enough for the sensor to detect any heat build-up. In either scenario, rub blocks can be dangerous and ineffective in detecting belt misalignments.
