M800 Speed Switch

Inductive Speed Switch Sensor
M800 Elite speed switch

The M800 Elite Speed Switch is designed to detect belt slip, belt underspeed, stop motion, low speed or zero speed on bucket elevators, conveyors, airlocks, mixers, fans, grinders and many other rotating machines. Totally sealed and simple to calibrate, the M800 Elite works in the harshest of conditions.

An inductive sensing device located in the nose of the M800 Elite enclosure will detect a metal target. This target can be an existing bolt head or device attached to a shaft. During installation the M800 Elite is set to the normal machine shaft RPM by calibrating with the magnet provided. The internal microprocessor sets the alarm and shutdown relays.

    4b Speedmaster - Testeur de contrôleur de rotation

    SpeedMaster™

    Allows speed switch calibration and testing while installed on the shaft.
    4B Whirligig shaft sensor mount

    Whirligig®

    The Whirligig® is a fully guarded target for easy mounting of motion sensors. It is a universal shaft sensor mount suitable for all industry standard cylindrical or DIN style inductive sensors including 4B's M100, M300, and M800 speed switch sensors.

    4B speed relay

    4B Speed Relay (USR)

    The Speed Relay is a microprocessor controlled digital speed monitor for use with 2, 3, 4 wire NPN/PNP sensors, 4B’s WDA range of sensors or Contact sensor inputs, with a user programmable electromechanical relay and PhotoMOS Solid State Relay (SSR) outputs. The Speed Relay has a 160x80 pixel LCD display to provide information, and 3 front panel buttons to program settings.

    X400 Elite

    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.

    New Product
    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.

    What voltage is needed for the M800 Elite?  
      The M800 Elite is universal voltage 24 - 240 VAC/VDC.  

    How do you calibrate the M800 Elite?  
      The M800 Elite is calibrated with a magnetic using the calibration point on the front of the sensor, please refer to the operation manual for details.  
         
    When will the M800 Elite alarm and/or shut down the machine it is monitoring?  
      The M800 Elite will provide an alarm at 10% underspeed and can provide an automatic shutdown at 20%.  

    Are the relays always open or closed?  
      The 10% relay is open when running and the 20% relay is closed when running.  

    Why is the M800 Elite not working when mounting to the Whirligig?  
      There are two sets of holes in the base plate of the Whirligig, be sure to use the top holes to mount the M800 Elite flush to the Whirligig guard and target.

    Hazard Monitoring Design Service

    Preventative maintenance can help reduce the risk of equipment failure and consequent downtimes. When it comes to monitoring your bucket elevators and belt conveyors, 4B can recommend you the ideal combination of sensors and monitoring systems to suit your requirements and budget.

    4B provides an extensive range of their own ATEX / IECEx / CSA approved hazard monitoring systems, misalignment switches and bearing temperature monitors and level controls. We can offer you anything from a replacement sensor to a fully integrated hazard monitoring system which can be operated either as a stand-alone system or connected to your PLC.

    And if you do not want to install hazard monitoring sensors on every piece of equipment in your plant straightaway, we can offer you a scalable solution starting with carefully chosen equipment and systems that can be expanded at a later date to encompass other machines in the plant.

    We can also offer you an installation service, and we do provide a competent after-sales technical service to help you overcome any technical problems with your monitoring equipment.
