A key precondition to laying a smooth pavement is using a material control system to maintain a constant head of material in front of the screed. The AC700MC Material controller monitors and regulates the material flow; controller and sensor are built into the same unit. It is operated with push buttons on an integrated keypad with an LED level indicator. The amount of material is easily changed by pushing either + or – on the keypad.
AC700MC controllers require a minimum of maintenance as it uses ultrasonic non-contact sensing, which eliminates the problem of clogging material on mechanical sensors and removes the need for supervision in use.
The AC700MC series are produced in several hardware versions to match the different types of pavers. Contact us for guidance on which AC700 sensor or controller is applicable for your specific machine.
