    Protect Your Equipment with TORQ Speed Switch Underspeed and Overspeed Models

    The TORQ Speedetex® ESS Electronic Speed Switch is used in bulk material handling/processing systems to monitor speeds of belt conveyors, screw conveyors, bucket elevators, rotary feeder shafts, rotating drums and other types of rotating machinery to protect elevators, feeders and conveyors from speed related damage resulting from broken belts, overloads, or belt slippages.

    The controls are easy to set with an LCD display to precisely set speed and/or monitor actual shaft speed. The dual function tachometer/speed switch, gives the user immediate feedback at the point of operation. A key feature of the switch is that it can be set without driving the unit. Input to the LCD display is made with four pushbuttons. Two of the pushbuttons increase or decrease set-point speeds. Another controls overspeed or underspeed selection. The fourth pushbutton sets the LCD readout to setpoint adjustment or the tachometer function. The LCD display indicates output logic (ON or OFF). The terminal block is Euro design to simplify terminal connections. The unit's enlarged case makes it easier to install and precisely set controls.

    Zero Speed Applications
    The ESS models below may be used as Zero Speed switches as well. To use the ESS to detect something stopping, the unit is set to the Underspeed mode. The user then defines zero speed for the application. The typical definition is one (1) RPM. How many RPM is considered zero speed can be chosen by the user. The ESS can also be used to detect the start of rotation as well if the unit is set to Overspeed. Then if the unit achieves one (1) RPM (or whatever value the user choses) the ESS will send out a signal to indicate that rotation has started.
