LEVEL MEASUREMENT
WE HAVE 3 TECHNOLOGIES FOR LEVEL MEASUREMENT
The technology suitable for any application would depend on the application and/or user preference.
THE TECHNOLOGIES AVAILABLE INCLUDE:
- Gamma
- Microwave
- Acoustic
PRODUCTS: LEVEL MEASUREMENT
WE OFFER TWO TECHNOLOGIES FOR CONVEYOR WEIGHING
- Electro-Mechanical (E/M) type – which employs load cell(s) to measure the loading on the belt and;
- Gamma type – which determines the load on the belt by measuring the absorption of gamma rays.
ELECTRO-MECHANICAL SCALES
Electro-Mechanical scales are available in many different formats. All the E/M scales employ strain gauge load cells and differ only in the weigh frame type/design. The weigh frames are available in measurement (weigh) spans from 1 metre through 8 metres and are available in either Standard or Counter-Balanced format.
NON-CONTACTING GAMMA SCALES
Non-contacting Gamma scales provide weighment without the troublesome effects such as; belt tension, alignment, wind etc. The Gamma scales are also extremely easy to install and require very little space, making them ideal for applications where E/M scales cannot fit.
THE CORRECT CHOICE OF SCALE MODEL DEPENDS ON:
- The Application.
- The Accuracy required.
- The Calibration facilities available
Our wide range of conveyor scale models allows measurement on almost any conveyor application including; Standard conveyors employing rubber belting, Chain conveyors, Bucket conveyors, Apron/slatted steel conveyors, Screw conveyors and Pipe conveyors.
All our conveyor scales use the same UNIPRO® Weighing Transmitter and PT-500 Digital Speed Sensor. This transmitter is also the same as that used in our Density/Mass flow gauges, Continuous Level Gauges, Bin Weighing systems etc.
These conveyor scales are suitable for use on belt widths of 150 mm through 2500 mm and capacities from 100 kg/h through 20 000 t/h.
PRODUCTS: ELECTRO-MECHANICAL SCALES
In Electro-Mechanical Conveyor Scales, the weight of material on the conveyor is measured by a weigh bridge which is installed into the conveyor. The weigh bridge incorporates high-accuracy strain gauge type load sensor(s).
The weigh bridges are available in various designs from single weighing idler arrangements, through eight weighing idler types. The weigh bridges are also available in either Standard or Counter-Balanced formats.The conveyor speed is measured by our high-resolution, all digital, PT-500 tachometer.
The Premium scale models have an “On-Board” calibration reference, allowing for easy and rapid checking of the weigh bridge calibration. This calibration reference may be safely operated, either manually or automatically. The Speed sensor may also be equipped with our Cal Check Mechanism, which allows the safe verification of tachometer calibration. The UNIPRO® signal processor (weighing transmitter) used is common to all the scale models.
PRODUCTS: NON-CONTACTING GAMMA SCALE
The Gamma-weigh® scale operates on the principle of gamma absorption. The “C- Frame” contains a (point) source of gamma radiation at the top and a (strip) gamma detector at the bottom.
