Sensor Advantages

▪ volume can be measured

▪ is working without any contact with the material

▪ the sensor is insensitive against dust and vabrations

▪ the sensor is insensitive against any move of the plant e.g. chaning of the gradient angle

▪ is measuring small volumes not relying on the weight

▪ measure is possible with any gradient of the conveyor - also if it is changed during the weighing

▪ measurres equal of the performance

▪ the measure of the conveyor speed effects through an inductive feeder mounted on the drive pulley

▪ the taring of the sensor effects through a taring to zero, once after the installation on the plant and only takes some seconds

▪ the weighing unit can be mounted in shortest time and needs no further calibration of the system

▪ all cables and mounting supports are extent of delivery

▪ Text fehlt!!!

▪ weighing record can be adjusted for the individual needs

Computer Sensor

▪ LCD display

▪ memory card scanner

▪ keyboard

▪ printer with continuous paper

▪ lockable, dust and weather prooved housing

The computer unit consists of an alpha numeric keyboard, easy to read LCD-Display, printer with continuous paper and a memory chip-card-scanner.

The memory card is used for taking all the saved data from the site back to the offfice to work with them e.g. in Exel (for invoicing).

Several information can be saved on the memory card:

▪ information of customer (name, adress)

▪ Name of working personel

▪ location

▪ jobsite

▪ material to be crushed

which can be printed out on the weighing record together with the date and time of weighing (start/end). The material specification and the names of the working personel can be saved for future use on the memory card and are changeable at any time.

The record informs you not only of the daily performance - it also lists the crushed material of the several periods. Because of the exact weighing-time-list on the printing record, you can examine the real working time of the weighing system, working personel and he real wear costs of the plant.

The Optical Belt Scale

The optical belt scale for material on discharge conveyors is measuring the material through a sending beam the receiving cameras pick up the sending beam and check the datas. The measuring datas are printed with the printer of the computer unit. This new measuring system has a lot of advantages in comparison with normally used weighing systems.

▪ is measuring the volume on the discharge conveyor through electro-optical sensor which is transmitting the received data to the computer unit

▪ on the printout you can receive the volume of the crushed material

▪ the sensor is fitted on a frame, which will be mounted directly on the head of the discharge conveyor. This prevents the direct contact of the sensor with the material as it is usual with other weighing systems - and therefor the system of Hartl Sensortechnik GmbH has no wear.

▪ the measure of the conveyor speed effects through an inductive feeder mounted on the drive pulley

▪ the sensor is insensitive against dust and vibrations as no moveable parts are mounted

▪ it also guarantees a further weighing without any differences when you are changing the angle of inclination (without taring to zero). This is a big advantage in operation with modern crushing plants, which are fully mobile, to make a flexible and economic operation possible.
