Belt Scales

The weight of the material on the belt is measured by a high-precision weighing sensor, and the running speed of the material is measured by a speed sensor.

The weighing bridge of the electronic belt scale is installed on the conveyor frame. When the material passes through the weighing bridge, the metering roller will directly act on the weighing sensor with the weight of the material on the belt, and the sensor will generate a voltage signal proportional to the material load.

The speed sensor is driven by the friction roller placed on the return belt. The friction roller rotates 360° under the action of the friction force of the belt. When the belt is running, the speed sensor generates a series of pulses. Each pulse represents a moving unit of the belt, and the frequency of the pulse is proportional to the belt speed. The weighing instrument receives signals from the weighing sensor and the speed sensor, and obtains an instantaneous flow value and cumulative weight value through integral calculation, and displays them separately.

The core weighing component of the product is a digital weighing sensor independently developed and produced by our company (imported sensor from Sequan, USA), which has high precision and reliable quality;

The core part of the speed measuring device adopts the Japanese Omron speed measuring encoder, with 360 pulses per cycle, more accurate speed measurement, double-wheeled trolley structure, and rubber coating process, which fits tightly to the belt to avoid throwing and slipping, with high precision and more stable performance;

The instrument is made of 304 stainless steel, with a large LCD screen and an external keyboard for direct operation, which is easy to use. The output signals include 4-20mA, 485 communication signals and ton pulse signals, which are suitable for various control systems such as DCS or PLC, and have strong versatility;

A data converter is configured to ensure that the sensor data can be instantly converted into anti-interference digital signals for transmission to ensure data stability;
