Screenmasters Launch Sensortechnik Scales in Australia

Screenmasters Australia are delighted to announce that they have recently acquired the exclusive rights to distribute one of the world’s most accurate weighing systems, Optical Belt Scales by Sensortechnik. These units can be fitted to mobile crushing and screening plants, shredders and trommels, as well as fixed plant conveying systems.

Sensortechnik Optical Belt Scales (OBS), developed and built in Austria over 10 years ago, have no moving parts and are not connected to any belt.

An electro-optical volume measuring sensor, built into the support frame, measures the cross-profile of the material on the conveyor belt with the feed rate of the belt measured by an inductive switch. The combined data is calculated and the result is the volume of the material on the belt. Independent tests have proven the OBS measurements to be 99.5% accurate.

The unit comes standard with a PDA and its own, handheld, Bluetooth printer unit. No printers are attached or built into the crushing or screening unit. The owner can nominate the clients name and product, select the measurements required in the PDA (i.e. 1.6 tonnes = 1 metre or 1.8 tonnes = 1 metre) and print reports immediately. These reports allow the owner to view what time the unit started at, tonnages every 30 minutes, how many times throughout the day the unit was turned on and off and of course total daily tonnages. It will provide monthly calculations as well as daily calculations with the data being stored for 1 year.

The Sensortechnik OBS is dust and vibration proof, as it has no moving parts and is able to work on very short belts and chevron belts, as well as all pivoting and foldable conveyor belts. It can be fitted in approximately 2 hours by 2 technicians and requires calibrating only once upon fitting. Even if the angle of the conveyor belt is changed the OBS does not need recalibrating. The PDA and printer are not mounted to the machine which means these devices cannot be influenced by vibration, temperature, dust or rain.

Sensortechnik have sold thousands of these units around Europe, 600 were sold in one year. They have never had a unit fail indeed the prototype unit built all those years ago is still in operation today.

The added advantage of these units is that it removes the pressure away from the loader drivers. No longer is it necessary to slow down and weigh every bucket of material before it is removed to stockpile, the drivers can just get on with their jobs without having to stress about counting every bucket of material coming from the crusher or screen. In addition the one year storage period gives the owner the opportunity for recourse if there is a dispute at some stage throughout the contract period. All the data is stored inside the sensor thus the information can be printed of and will assist in the resolution of any dispute over tonnages.

Sensortechnik Optical Belt Scales are available ex-stock and can be fitted to mobile units 600mm – 1,400mm and fixed plant belts up to 2,400mm.
