via an antenna 48 over the wireless communication link 36 or over the ohmic connection 38 from the receiver 33 embedded in the conveyor belt the receiver 46 sends the measurement signal to the remote controller 44 a transmitter 47 connected between the controller 44 and the antenna 48 or the ohmic connection 38 may be used to send command and control signals to the belt borne accelerometer circuits an operator input device 50 connected to the controller 44 may be used to select accelerometer or alarm settings or data to be displayed the controller 44 may also be used to stop or control the speed of a motor 52 driving the main drive sprockets 18 or to activate a clamping damper 64 acting on the conveyor belt itself a video display 54 may be used to monitor system operating conditions and settings or to display alarm conditions a more clearly visible or audible alarm 56 may also be used by the controller to warn of irregularities in the process the controller may be a programmable logic controller a laptop a desktop or any appropriate computer device instead of or in addition to belt mounted accelerometers other sensors 62 can be used.
