nouvelles de l'entreprise New 369-4794 Level Gauge Paver Material Level Sensor for AP655F AP355 Asphalt Paver

Maintaining a constant head of material in front of the screed is one of the most important factors for producing a smooth, dense and uniform asphalt surface. The 369-4794 Level Gauge / Material Level Sensor is the sensing element at the heart of the automatic material feed control system used on AP655F and AP355 asphalt pavers. This non-contact ultrasonic sensor continuously measures the height of the asphalt mix in front of the screed and sends a signal to the machine controller, which automatically adjusts the speed of the conveyors and augers to keep the material level constant.

The 369-4794 is a direct replacement spare part built to match the original mounting points, connector and signal output of the OEM unit. It is manufactured from durable steel with a protective gray finish and is supplied as a 100% new component. Because it uses ultrasonic non-contact measurement, it is not affected by the temperature, viscosity or color of the paving material, making it reliable in demanding road construction environments.

• Non-contact ultrasonic sensing — reliable, maintenance-friendly measurement that is not disturbed by material temperature, viscosity or color.
• Accurate material height control — helps keep a constant material head for smoother, more uniform paving.
• Direct-fit replacement — matches the mounting and wiring of the original 369-4794 part for fast installation.
• Durable steel construction — built to withstand vibration, dust and daily jobsite conditions.
• Compatible with AP655F / AP355 — designed for these popular asphalt paver models.
• 1-year warranty — supplied with comprehensive after-sales and online technical support.

The system works as a closed control loop. First, the ultrasonic sensor continuously measures the distance to the surface of the material pile in front of the screed. Second, the machine controller compares this measured distance with the ideal height preset by the operator. If the material level is too low, the controller increases the feed speed; if the level is too high, it reduces the feed speed. Finally, the controller sends an electrical signal to the hydraulic proportional valves that drive the conveyors and augers, changing the material feed rate. The sensor then detects the new level and the cycle repeats, keeping the material head in dynamic equilibrium and delivering a continuous, uniform supply of mix to the screed.
