System composition

The ICS-17A electronic belt scale consists of four parts: ICS-17A weighing bridge, weighing sensor, 60-12C speed sensor and speed roller, and 2001 weighing controller.

Weighing bridge

The ICS-17A weighing bridge is equipped with four sets of rollers on the double bar, supported by two pull type sensors in the middle, and supported by frictionless ear pivot points on the outer side. Effectively overcoming the impact of biased loads on accuracy, this enclosed device can prevent vibration, moisture, corrosion, and material accumulation, thus avoiding the problems caused by the use of blade devices and bearing devices in harsh environments. The main beam of the weighing bridge is made of rectangular steel pipes, which gives the entire weighing bridge sufficient rigidity, small self weight, and minimal external dust accumulation area. In order to ensure the stability of the entire system, high-precision resistance strain gauge sensors are installed at the tensile position to reduce nonlinear errors.

The ICS-17A weighing bridge can be directly installed in various belt conveyor frames of different widths, located between the upper and lower belts, without occupying space height. It is an assembled whole in the factory, which can be quickly and conveniently installed and calibrated. The weighing bridge is suitable for belt widths ranging from 400-2000mm

load cell

The ICS-17A series electronic belt scales all use pull type electronic strain gauges.

The main technical indicators are as follows:

◇ Shell: "S" type sealed protection

◇ Nonlinear:<0.03% FS

◇ Non repeatability:<0.01% FS

◇ Creep:<0.02% FS

◇ Zero point output: ± 1%

At maximum flow rate, the displacement of the force application point of the sensor elastic body shall not exceed 0.2mm

◇ Temperature sensitivity: Interval: 0.0008% FS/OF

Zero point: 0.0015% FS/OF

◇ Lag error: 0.02%

Sensitivity error: ± 0.1%

◇ Overload capacity: 150% of sensor capacity

Speed sensors 60-12C, 60-12B

The speed sensor is installed on the tail drum, large-diameter drum or speed roller, and the speed roller/roller is installed on the upper surface of the return belt, eliminating the impact of belt slippage. The speed sensor is a digital brushless pulse generator. When the belt is running, the speed sensor emits a series of speed pulses, each pulse representing a unit length of the belt travel. The pulse frequency is proportional to the belt speed.

The shell material is cast aluminum, which can adapt to outdoor working environments.

The communication pulse generator does not require adjustment or replacement of the carbon brush

Brushless AC pulse generator, no adjustment or calibration required, maintenance free

The latest soft connection technology ensures more effective speed measurement accuracy and greatly improves the service life of equipment

2001 Weighing Control Instrument

Using a 32-bit CPU and a 24 bit A/D converter, it speeds up operation and improves measurement accuracy;

All data from the belt scale is displayed on a high brightness four line vacuum fluorescent screen;

The menu style panel operation mode conforms to people's computer operation habits;

When the data related to the belt scale is changed, the original data can be retained for querying to reduce human errors;

◆ Provide multi-level password protection to facilitate different users; Provide linear compensation to ensure the same accuracy of the belt scale between 25% and 100% of the rated load;

◆ Optional analog output for displaying material flow, weight, or speed;
