HS301 One-sided paving control

HS301 is a paving control of Mini-Line® product family. It controls the elevation and slope of the paver's screed by automatic regulation of the tow arm height on either right or left side of the machine.

The system works with a variety of sensors in order to thoroughly meet the demand of your different paving jobs: G221 Mono-Sonic or G224 Multi-Sonic sensors, S298 Slope sensor or LS350 laser receiver with linear millimetre resolution over the entire reception window.

You can also use averaging beams with three to six ultrasonic sensors in a row to level out smaller height irregularities if the subbase or ground serves as levelling reference and lay a smoother asphalt mat. With this method there is no need for a surveyor to lay-out a reference string-line.

Our tip: In order to have a levelling kit ready for virtually all applications we recommend our Mini-Line® base kit consisting of HS301 handset and controller, plus our G224 Multi-Sonic sensor that copies the height from a ground or a string-line. Add to this our slope extension kit and the Compact or Super Averaging beams with extra 3 to 5 Mono-Sonic sensors G221.

PL2005 two-sided paving control

Our PL2005 is a double sided paving elevation control of the Mini-Line® product family. One system controls the levveling of both left and right sides of a paving screed.

Same as HS301, PL2005 works with a variety of sensors in order to thoroughly meet the demand of your different paving jobs: G221 Mono-Sonic or G224 Multi-Sonic sensors, S298 Slope sensor or LS350 laser receiver with linear millimetre resolution over the entire reception window.

You can also use at each side averaging beams with three to six ultrasonic sensors in a row to level out smaller height irregularities if the subbase or ground serves as levelling reference and lay a smoother asphalt mat. There is no need for a reference string-line.

Core component of PL2005 Mini-Line® system is the interface box where one or two operating panles and all sensors will be connected to. Typically, small pavers will need only one control panel, while pavers with a large screed may use two panels.

The operating panel features easy-to-understand displays and keypads. The operation is logical and well-arranged. The LED display is bright and clearly visible even under direct sunlight.

Sensors for Mini-Line®
G224 Multi-Sonic Ski

G224 Multi-Sonic Ski

G224 Multi-Sonic

Our G224 is a versatile, precise and heavy-duty sensor with four ultrasonic transducers in a row that can detrmine the height over a subbase, as well as above a string-line. Moreover, it has a side display that is used for aligning the screed to the guiding string-line.

Product features:

  • Four, encapsulated, heavy-duty ultrasonic transducers in a row
  • Integrated averaging over the span of the receiver
  • Temperature compensation by a stainless steel bail in measurement direction
  • 1 mm accuracy
  • Robust, water- and dustproof
G221 Mono-Sonic Sensor

G221 Mono-Sonic Sensor

G221 Mono-Sonic

G221 is a budget-priced ultrasonic sensor with one transducer. It will detect the height over a subbase or ground or kerbstone, and even over the hot asphalt mat. However, it is not applicable for measurements above a string-line. LED indicators will display the elevation info that is permanently send to our Mini-Line® paving control.
We recommend using this sensor in multiplex setups with our Compact or Super Averaging Beams.

Product features:

  • One ultrasonic transducer encapsulated in a heavy-duty housing
  • Low investment budget
  • Temperature compensation by stainless steel bail
  • 1 mm precision
  • Robust, water- and dustproof
S298 Slope sensor

S298 Slope sensor

S298 Slope sensor

Our S298 slope sensor was develloped for high-compacting paving screeds. It withstands enduring and strong virbrations. The sensor will reliably and precisely measure the cross slope with a resolution of ±0,1 % and sends the data to our Mini-Line® paving control.
The S298 sensor has two connection sockets and can be hooked to the HS301 controllers at the left and/or right side.

Product features:

  • Heavy-duty and precise inclinometer
  • Extremely vibrationproof
  • Working range from -9,99% to +9,99%
  • ±0,1 % accuracy
  • Robust, water- and dustproof
ULS250 laser receiver

ULS250 Laser

ULS250 Laser

Our ULS250 laser receiver is linear (sometimes called proportional). That means that the centre on-grade can be moved to any offset position, in case of our ULS250 with one millimetre resolution over the entire 25 cm reception height. Thus, this laser receiver is perfectly suited for for precise asphalt laying jobs. The ULS250 captures the laser beam of all red and infrared rotating lasers. The most common application is asphalt laying in places, parking areas, airports, etc.

Product features:

  • Linear with free offset on-grade
  • 25 cm reception height
  • 1 mm accuracy over the whole working height
  • Ultrabright LED height indicators
  • Heavy-duty design with internal shock-mounts
  • Water- and dustproof
Compact Averaging Beam

The Compact Averaging Beam is a levelling extension of Mini-Line®. Four ultrasonic sensors mounted to this split beam measure the elevation above the reference subbase or kerbstone and send them permanently to the Mini-Line® paving control. The control uses the multiplexing method to average the height measuring results of each individual sensor, and regulates the tow-arm of the paver accordingly. As a result, small irregularities and bumps of the subbase will be smoothed out.

Easy Averaging Beam

Using the Compact Averaging Beam

There is no difference in smoothness or tolerance when using G221 Mono-Sonic sensors with the Compact Averaging Beam instead of G224 Multi-Sonic sensors; it simply saves your investment budget.

The split beam makes it easy to assemble and dissassemble the Compact Averaging Beam in the morning and evening. For transportation it can be collapsed to a size that it will fit into the luggage compartment of a standard car.

Moreover, the split design allows a free access to the side of your paving machine.

Super Averaging Beam

The Super Averaging beam is a professional extension of Mini-Line® paving control. You can mount from three to six ultrasonic sensors to this beam, no matter if G221 mono-sonic sensors or G224 multi-sonic sensors.
There are two versions: 9 m (4 segments) and 13 m (6 segments). The aluminium segments will be hooked to each other. There is an optional flexible hinge to swivel the last sensor above the freshly laid asphalt mat. The segments have built-in cables and plugs to connect the sensors (in 18 positions), or add-on ultrabright LED lights to illuminate the working area.

Super Averaging Beam

Using the Super Averaging Beam

The Super Averaging Beam is applicable when the subbase is the elevation reference. It will smooth out irregularities and bumps over the span width of the beam. The best results of smoothness will be reached using 6 ultrasonic sensors mounted to the 13 m Super Averaging Beam. This will even larger bumps, pot-holes or waves in the subbase, if you use the Averaging beam layer after layer starting with the base layer, then the binder course and finally the covering layer.
