Milli-Speed Switch

Underspeed Monitor
New Product
4B  Milli speed switch (ATEX version)

The Milli-Speed Sensor has a 4-20 mA output proportional to calibrated speed, it is designed to allow detection of belt slip & 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 Milli-Speed works in the harshest of conditions.

An inductive sensing device located in the nose of the Milli-Speed enclosure will detect a metal target. This target can be an existing bolt head or device attached to a shaft, such as 4B’s Whirligig® sensor mount. During installation, the Milli-Speed is set to the normal running RPM by simple magnetic calibration.

    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 sensor mounting kit

    4B Sensor Mounting Kit

    The 4B Sensor Mounting Kit is able to securely mount barrel sensors in position, including 4B’s range of 18 & 30mm wide inductive sensors.

    New Product
    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.

    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 Milli-Speed? 

    The Milli-Speed is looped powered and requires 17 - 30 VDC.


    How do you calibrate the Milli-Speed? 

     The Milli-Speed is calibrated with a magnetic using the calibration point on the front of the sensor, please refer to the 

     operation manual for details. 
     

     Why is the Milli-Speed 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 Milli-Speed 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.
