Outdoor Rainproof Asphalt Paver Sensor 70618034 for Automatic Leveling Control Now in Stock

Stock of the outdoor rainproof asphalt paver sensor, part number 70618034, is now available for paver leveling systems. The unit is supplied as a complete sealed sensor for automatic grade and slope control, available from one set with a seven to ten working day lead time on stock items.

Wet weather is where leveling control is lost

Automatic grade and slope control depends on a stable reference signal from the sensor mounted on the screed arm. In dry conditions most sensors perform acceptably. The problems appear when it rains: moisture reaches the housing, dust turns into a conductive film, and the signal begins to drift. The control system corrects for a reference that is no longer accurate, and the mat shows it as a wave pattern or as density that changes from one side to the other.

Operators usually notice the fault before the machine does. The system drops to manual, the sensor has to be re-zeroed between passes, or the grade readings shift after a wash-down at the end of the shift. In most of these cases the housing seal or the cable entry has failed, not the machine's control unit.

Product specification

Construction and protection

• Sealed rainproof housing for paving in wet weather
• Dust and grit protection at the sensing face and cable entry
• Vibration resistant internal mounting for continuous screed operation
• Shielded cable to limit interference from machine electrical systems
• Corrosion resistant coating for site storage and transport
• Function tested unit by unit before packing

Installation and fitment

The sensor mounts in the standard position on the screed arm and connects to the existing harness without modification. Because leveling accuracy depends on the complete chain of sensor, cable and control unit, it is worth checking the harness for chafing and the connector for corrosion at the same time. Where a machine has been rebuilt with non-original components, send the machine model and the part reference from the manual to have fitment confirmed before shipment.

Typical replacement signals

• The leveling system switches itself to manual during paving
• Grade readings drift in wet conditions or after washing
• The sensor needs re-zeroing between passes
• Signal loss appears intermittently with no change in paving speed
• Moisture visible inside the housing or at the cable entry

Supply and support

We supply spare parts for asphalt pavers, road milling machines and rollers to contractors, rental fleets and aftermarket distributors. Minimum order is one set, stock items leave in seven to ten working days, and mixed orders across leveling system components can be quoted together to consolidate freight.
